Second Life Ranker Character Guide: Every Named Cast

TL;DR: Second Life Ranker character guide, checked against AniList's own character database rather than a fan wiki: Yeon-woo Cha and the tower alias Cain he climbs under, his dead twin Jeong-woo, the One-Horned Tribe royals who become his closest allies, and Leonte, the ranker AniList confirms as one of Jeong-woo's five killers.

Search "Second Life Ranker characters" and the results are a Fandom wiki with inconsistent romanizations and a scattered Reddit thread or two. The review covers whether the dead-twin diary premise earns its 8.0/10. The reading guide covers where each season starts and how the pacing shifts across 219 chapters. Neither one puts a verified name next to every face in the Obelisk.

This is the Second Life Ranker cast explained the way it should have been from the start, sourced against AniList's character database rather than assembled from memory. For the full verdict on the diary mechanic and where Second Life Ranker earns and loses points, read the Second Life Ranker review. For the arc-by-arc breakdown of all three seasons and where to start reading, see the Second Life Ranker reading guide. This page exists to answer a narrower question: who is who, and what does AniList's own data actually confirm about them.

Key Takeaways

• Yeon-woo Cha is AniList's sole main-cast entry for Second Life Ranker, and the site's character data links him to the alias Cain, the name he climbs the Obelisk under before his identity becomes known to his closest allies.
• Jeong-woo Cha, Yeon-woo's younger twin, was one of the Tower's strongest and most famous high-rankers before five people betrayed and killed him. AniList names one of the five directly: Leonte.
• Edora, Phante, and their father Nayu (the Martial King) are the One-Horned Tribe's royal family, and AniList's bios cover their individual positions in more detail than most recap coverage bothers with.
• Sesha is confirmed on AniList as Yeon-woo's niece, and her reveal is one of the moments AniList's own bio for Yeon-woo marks as a turning point in how guarded he is with the people around him.
• This Second Life Ranker character list traces every name back to AniList media entry 109957, queried live this session rather than pulled from a fan wiki.

Second Life Ranker Character Guide: Yeon-woo Cha and the Alias Cain

Yeon-woo Cha is the only character AniList credits as series-main, and the bio holds more specific detail than the one-line "revenge-driven protagonist" summary most coverage settles for. He's 182 cm, a former special-forces soldier before the story starts, and he reawakens as what AniList's bio calls a "Dragon Human" after receiving power tied to Jeong-woo's pocket watch, the same watch that holds his brother's encrypted diary. That transformation is what makes him a player in the Obelisk's system at all. Without it, he doesn't climb the tower. He just grieves outside it.

The detail that separates this protagonist from a standard revenge lead is easy to miss if you're only reading for plot beats. AniList's bio describes him as a hard worker rather than a natural. He has to try over and over to solve a problem his brother would have solved on instinct, and he hides that effort on purpose. Jeong-woo did things effortlessly. Yeon-woo doesn't, and the diary he's climbing with belonged to someone whose talent he spent a lifetime standing next to.

Note: AniList's character data for Edora links her storyline to Yeon-woo under the name Cain, the alias he uses while climbing the Obelisk. Readers who've only seen "Yeon-woo" used across this site's review and reading guide should know both names point at the same person. The Tower doesn't know who Yeon-woo Cha is until he decides to let it.

That alias matters more than a naming footnote. Cain is how Edora, Phante, and most of the rankers around him first encounter Yeon-woo, before any of them know about the dead brother, the diary, or the betrayal driving him forward. AniList's own bio for Yeon-woo describes the moment his face and his real identity are revealed to allies including Phante and Edora as a genuine turning point: he becomes "considerably warmer and less cynical" once he stops treating the people around him with the same paranoia his brother's story taught him to default to.

One more thing before you meet him on the page: Yeon-woo has, per his own AniList bio, a very poor sense of imagination when it comes to naming things, with a habit of picking names a toddler would pick. He names a newborn phoenix "Chirpy." He tries "Growl" and "Roar" for a dragon. It reads as condescending until the bio clarifies he genuinely likes those names, a small, specific, unglamorous detail that most competing character rundowns skip because it doesn't fit the revenge-plot pitch.

Jeong-woo Cha and Sesha: the Family the Revenge Is Built Around

Jeong-woo Cha is Yeon-woo's younger twin, and AniList's bio for him complicates the "genius who died" framing most recaps reach for. He's described as weak and introverted growing up, someone who liked books and movies and succeeded at most things without needing to work hard for it, the opposite of the effort Yeon-woo puts in. He also left home specifically to find a cure for their mother's illness, a detail that reframes his time in the Obelisk as something closer to a desperate errand than a straightforward power quest.

By the time the story catches up to him, Jeong-woo is one of the strongest and most famous high-rankers the Tower has produced. That status is exactly what makes his death land as a betrayal rather than a loss to an enemy. AniList's data confirms he was killed by a group of five people, rankers he'd presumably trusted enough to team up with, not enemies fighting him head-on. One of the five, Leonte, gets his own confirmed entry below. The other four aren't individually named in AniList's current character database, and this guide isn't going to guess at filling them in.

Sesha is where the family stakes widen. AniList's own bio for Yeon-woo describes her plainly as his niece, and it marks the moment his face and his connection to her are revealed to Phante and Edora as the point where he starts genuinely trusting the people around him instead of treating everyone with his brother's paranoia. Sesha's own character entry adds one more detail without spelling out the full reveal: she's raised in the care of a guardian named Brahm, tied to a fuller backstory AniList's own page marks as spoiler content. This guide stops there and leaves the rest for the page itself.

Second Life Ranker Character Guide: the One-Horned Tribe Royals

Most of Yeon-woo's early allies come from one family, and AniList's bios give them enough individual detail to stop treating them as a single tribe-shaped block.

Edora is a member of the One-Horned Tribe's royal family, the daughter of the tribe's king and the younger sister of Phante. AniList describes her as calm and collected, someone who speaks politely and doesn't waste time on anything unnecessary, cold toward most people by default. That changes specifically around Yeon-woo. After meeting him under the alias Cain, AniList's bio confirms she develops romantic feelings for him, to the point of visibly blushing when someone brings up the two of them as a couple. It's a rare crack in a character otherwise described as guarded.

Nayu, credited on AniList as the Martial King, is the One-Horned Tribe's ruler and Edora and Phante's father. He's one of the Tower's Nine Kings, and the only one of them capable of rivaling someone called the Summer Queen in individual combat strength, which places him near the top of the Obelisk's entire power structure. AniList's bio calls him carefree, mischievous, and genuinely unpredictable to both his own tribe and outside rankers, harmless-seeming whimsy that turns out not to be harmless at all. The same bio notes he's just as capable of the tribe's characteristic bloodlust, usually saved for enemies and for keeping his own men in line.

Underneath the intimidation, though, he's a real father. He dotes on Edora, trains Phante hard enough that the training reads as borderline brutal, and teases both of them in ways AniList frames as affection rather than cruelty.

Phante is Nayu's son and the tribe member most likely to inherit the throne. AniList credits him to the Cheonglam family specifically, with his mother serving as the tribe's current Psychic Medium, a detail that ties his claim to a role beyond simple bloodline succession.

The One-Horned Tribe's internal politics run in the background of Yeon-woo's climb: who's next in line, how Nayu's unpredictability shapes tribe strategy, what Edora and Phante's rise means for their father's rule. None of it becomes the story's main focus. Tower of God builds an entire ensemble narrative out of exactly this kind of tower-politics detail; Second Life Ranker keeps it as texture around one family instead.

Tower Rivals, System Figures, and the Man Who Killed Jeong-woo

Not every entry on this Second Life Ranker allies and rivals list is family or romance. AniList's database also confirms a handful of tower-system figures and rivals worth knowing before you start reading.

Doyle is one of the Tower's confirmed super rookies, ranked 11th on the Tutorial's rankings before Yeon-woo ever started his own tutorial run. AniList describes him as extremely lazy, someone who doesn't care about much outside of sleeping, clever but still immature given his young age. He's less a villain than a benchmark, an early rookie already outperforming most climbers by the time Yeon-woo shows up with nothing but a dead man's notes.

Yul is a player who previously climbed the Tower, and AniList's bio frames him as a determined kid who's prone to cowering when bullied, the way most boys his age would, but capable of standing his ground once he's pushed too far. It's a small, specific characterization rather than a power-scaling entry, and that's exactly why it's easy to miss in coverage that only tracks who's strong.

Yvlke holds a system role rather than a personal one. AniList lists him as the Floor Guardian of Floor 0, the Tutorial floor, and one of the leaders among all the Tower's Floor Guardians. Think of him as the gatekeeper: the figure whose job is standing between new climbers and the rest of the Obelisk.

Leonte is this early cast's one confirmed named villain. AniList credits him as a high-ranker of Cheonghwado, dubbed the Fist God, and one of that clan's five leaders. He was previously a high-ranker and executive of a different organization called Arthia before defecting once he judged it was headed for destruction, and AniList states plainly that he was one of the five people who directly killed Jeong-woo Cha. Everything Yeon-woo is climbing toward eventually runs through a name like this one.

Second Life Ranker's cast stays smaller and more tightly wound around one family than a series like SSS-Class Suicide Hunter, which spreads its own tower-system rivals across a wider ensemble. Readers who want more manhwa built around this specific mix of tower setting, information advantage, and grief-driven revenge have options beyond Second Life Ranker itself, sorted by which specific element hooked you, in the manhwa like Second Life Ranker guide.

Step-by-Step

Here's roughly the order this cast enters the story, useful for lining up a name against wherever you currently are in the 219-chapter run.

1. Yeon-woo Cha, introduced from the opening chapters as a former soldier discovering his twin brother's death and the encrypted diary left behind.

2. Jeong-woo Cha, established through the diary and early flashbacks as the dead twin whose documentation of the Obelisk becomes Yeon-woo's map.

3. Cain, the alias Yeon-woo adopts once he actually enters the Tower, the name most other characters know him by before his real identity comes out.

4. Doyle, appearing early as one of the Tutorial's ranked super rookies, a benchmark for how fast Yeon-woo is climbing relative to the Tower's own talent pool.

5. Yvlke, entering as the Floor Guardian overseeing the Tutorial floor Yeon-woo has to clear first.

6. Yul, appearing among the players Yeon-woo crosses paths with during the earlier climb.

7. Edora and Phante, introduced together as the One-Horned Tribe's royal siblings, arriving as Yeon-woo's climb starts intersecting with tribe politics.

8. Nayu, entering as Edora and Phante's father, the Martial King, once the story pulls back to show the tribe's leadership.

9. Leonte, confirmed later in the story as one of the five rankers responsible for Jeong-woo's death, the point where the revenge plot gets a specific face attached to it.

10. Sesha, revealed as Yeon-woo's niece later in the run, alongside the moment his identity as Cain becomes known to his closest allies.

That order tracks roughly how the manhwa introduces this cast rather than a wiki's alphabetical listing, since several of these names only make sense once you know what part of the climb introduced them.

Common Character Mix-Ups

A few names in this cast get flattened or confused in fast recaps. Here's how to keep them straight before you start reading.

Yeon-woo Cha and Cain are the same person. This site's review and reading guide use "Yeon-woo" throughout, since that's the name most English-language coverage defaults to; AniList's character data confirms "Cain" as the alias he climbs under before his identity becomes known. Neither name is wrong. They just apply at different points in the story.

Second Life Ranker and Ranker Who Lives a Second Time are the same series under different English titles. AniList lists "The Ranker Who Lives Twice" and "Ranker Who Lives a Second Time" among the series' recorded synonyms alongside "Second Life Ranker," the title this site and Tapas's official English release both use.

Yeon-woo and Jeong-woo are easy to mix up on the page given how close the names look in English romanization. Yeon-woo is the surviving twin and the series protagonist; Jeong-woo is the dead younger twin whose diary sets the whole plot in motion. If a scene references "the diary," it's Jeong-woo's. If it references "the player" currently climbing the Tower, it's Yeon-woo.

The One-Horned Tribe's royal family and the Tower's Nine Kings aren't interchangeable either, even though Nayu belongs to both categories at once. Nayu is one of the Nine Kings because of his individual strength; the One-Horned Tribe is the political structure he rules over, with Edora and Phante positioned as his heirs inside it.

Second Life Ranker Character Guide: Tips for Reading This Cast

Track this Second Life Ranker character list by relationship to Yeon-woo first, tower rank second. A name's importance in a given chapter usually comes down to whether they're family, someone Cain has to win over, or someone tied to the five who killed Jeong-woo, not how high they've climbed.

Keep Cain and Yeon-woo mentally filed as the same person operating in two modes: guarded stranger to most of the cast, grieving brother underneath it. Watching for the moment a character learns his real name is a reliable way to track how much he actually trusts them.

Don't assume every early rival stays a rival. Doyle's introduction as a ranked super rookie reads like a setup for antagonism, and AniList's own bio leans into that with the lazy, immature framing. Whether that holds up as the story continues is exactly the kind of thing worth tracking as you read rather than assuming from a Tutorial-arc introduction.

Watch for Leonte specifically once the revenge plot narrows its scope. He's the one name in this early cast AniList confirms as directly responsible for Jeong-woo's death, which makes him a more load-bearing character than his early page count would suggest.

Frequently Asked Questions

Who is the protagonist of Second Life Ranker?

Yeon-woo Cha, AniList's sole main-cast entry for the series. He's a former special-forces soldier who reawakens as a "Dragon Human" after receiving power tied to his dead twin brother Jeong-woo's pocket watch, which is what turns him into a player able to climb the Obelisk at all.

Is Cain the same person as Yeon-woo in Second Life Ranker?

Yes. AniList's character data links Edora's storyline to Yeon-woo under the name Cain, the alias he climbs the Obelisk under before his real identity and his connection to Jeong-woo become known to his closest allies. This site's review and reading guide use "Yeon-woo" throughout; "Cain" is how most other characters know him for a large stretch of the story.

Who is Sesha in Second Life Ranker?

Sesha is confirmed on AniList as Yeon-woo's niece. His own character bio marks the reveal of his identity and his connection to her, alongside allies including Phante and Edora, as a genuine turning point: he becomes noticeably warmer and less guarded once he stops defaulting to the paranoia his brother's story taught him.

Who killed Jeong-woo Cha in Second Life Ranker?

AniList's character database confirms Jeong-woo, one of the Tower's strongest and most famous high-rankers, was killed by a group of five people. Leonte, a high-ranker of Cheonghwado known as the Fist God, is the one member of that group AniList names directly. The other four aren't individually confirmed in AniList's current character data.

Is Edora a love interest for Yeon-woo in Second Life Ranker?

Yes. AniList's bio describes Edora, a member of the One-Horned Tribe's royal family, as cold and businesslike toward most people, but notes she develops romantic feelings for Yeon-woo after meeting him under his alias Cain, to the point of visibly blushing when their relationship comes up in conversation.

What is the One-Horned Tribe in Second Life Ranker?

The One-Horned Tribe is the royal family and political structure ruled by Nayu, credited on AniList as the Martial King and one of the Tower's Nine Kings. His children, Edora and Phante, are positioned as his heirs, with Phante named as the tribe member most likely to inherit.

Is this Second Life Ranker character guide based on the manhwa or the web novel?

The manhwa. Every name and detail in this guide traces back to AniList's character database for the manga entry (media ID 109957), checked live rather than pulled from a fan wiki. Where a detail isn't confirmed there, this guide leaves it out rather than guessing.
