TL;DR: Eleceed character guide, verified against AniList and Wikipedia rather than a fan wiki: Jiwoo Seo, Kayden Break, the Awakened world's ranking system, and every named ally and rival at Frame standing in their way.
Search "Eleceed characters" and most results either repeat the same first-name-only summary WEBTOON's own series page gives, or lean on a Fandom wiki someone edited from memory. Neither confirms surnames, neither explains the ranking system the cast keeps referencing, and at least two of this site's own earlier Eleceed articles got the protagonist's surname wrong. This guide fixes that: every name below is checked against AniList's character database and cross-referenced with Wikipedia's dedicated Eleceed entry, not pulled from recall.
Key Takeaways
- Jiwoo Seo and Kayden Break are the confirmed names for Eleceed's two leads, per AniList and Wikipedia. Several existing recaps, including two on this site, use Jiwoo Choi and Kayden Week instead.
- Frame is the antagonist organization AniList's bios name most often. Confirmed executives: Muse (Alpha), Roist, Morthius, Vatore, and Earthquake.
- The Awakened world runs a tiered global ranking (Top 10, Top 50, Top 100) that's distinct from any single school or organization's internal ranks.
- Key allies span two circles: the World Awakened Academy (Garrith Luterain, Leah Eresby, Veramonte and Ian Patrick) and the Shinhwa Association (Ji-Yeong Yu, Ji-Seok Yu).
- The series title is itself a clue: Wikipedia confirms "Eleceed" is a portmanteau of Electricity and Speed, tracking Jiwoo's ability set as it evolves under Kayden's training.
- For the verdict on the series, see the Eleceed review. For where each of these characters enters the 400+ chapter run, see the Eleceed reading guide.
Eleceed Character Guide: Overview
Eleceed opens with a mismatch that the title itself half-explains. Jiwoo Seo is a high schooler who has hidden his cat-like reflexes and super speed his entire life, using them to quietly help strangers and rescue strays instead of drawing attention. Wikipedia's entry on the series confirms where the name comes from: "Eleceed" combines Electricity and Speed, the two halves of what Jiwoo's ability becomes once Kayden starts training him. It's a small detail, but it's the kind of thing that gets lost when a summary only covers plot.
The injured cat Jiwoo takes home turns out to be Kayden Break, the strongest unaffiliated Awakened alive, trapped in an undignified body after a mission went wrong. Kayden can't act on any of his old strength without Jiwoo's cooperation. Jiwoo suddenly has the most dangerous trainer in the world. Everything else in this cast, the Awakened Academy, the Shinhwa Association, Frame's executives, builds outward from that one mismatched partnership.
This guide doesn't repeat the Eleceed review's verdict on whether the series holds up, or the reading guide's arc-by-arc breakdown of the 400+ chapter run. It sits next to both, answering a narrower question: who is this specific name, and how do they connect to Jiwoo and Kayden.

Jiwoo Seo and Kayden Break: The Two Leads
Advertisement
AniList's character database lists exactly two MAIN-role entries for Eleceed, and they're the pairing the whole series runs on.
Jiwoo Seo (AniList also records the alternate romanization Ji-Woo Seo) is described as bright and kind to the point of going out of his way for people who don't ask for help. His defining ability is super speed, sourced from cat-like reflexes he's hidden for most of his life out of fear people would treat him differently if they knew. Before Kayden, AniList's bio notes he had no close friends for exactly that reason.
Kayden Break carries an alternate credit on AniList that reads as a small joke by the series itself: Casein Nitrate, an anagram of his real name. He's introduced as a secret agent on the run, stuck in a fat, aging housecat's body. AniList's description is specific about his standing: strong enough to overpower people trained by organizations that have spent years studying exactly how to fight him. None of that strength helps while he's a cat who can't open his own food.
Neither name matches what several existing recaps use. Fan wikis and at least two of this site's own earlier Eleceed pieces refer to the protagonist as Jiwoo Choi and to his mentor as Kayden Week. AniList's character database and Wikipedia's dedicated Eleceed entry both independently confirm Seo and Break as the correct surnames, so that's what this guide uses throughout.
The anime side confirms the same protagonist under a different name entirely. AniList's entry for the 2027 Dandelion Animation adaptation credits Junya Enoki as Jiwoo Seo's Japanese voice actor. He's known for voicing Yuji Itadori in Jujutsu Kaisen. That casting detail sits outside the manhwa's own character data. It's a useful independent confirmation that Seo, not Choi, is the name productions are actually building around.
Jiwoo Seo and Kayden Break, individually credited on AniList's character database under the surnames this guide uses throughout.
Key Allies: The Awakened Academy and the Shinhwa Association
Jiwoo and Kayden don't operate alone, and AniList names two distinct circles that back them.
At the World Awakened Academy, Garrith Luterain serves as headmaster. AniList credits her with an ability called Animal Communion. She fights alongside a mythical owl named Phoenix and is identified as the grandmother of a character named Cain Luterain. Leah Eresby is the Academy's student council president and one of its own top-10 ranked students. That's a school-level distinction, worth keeping separate from the Awakened world's global rankings (more on that below). Veramonte Patrick is confirmed as one of the world's strongest top-10 Awakened overall. He has two grandsons tied to the Academy: Ian Patrick, whose ability is Shadow Manipulation, and his older brother Jurion. Rounding out the Academy's staff, Seong-Ik Han is its current principal. He's also a former leader of a group called Baekho, once considered the strongest Awakened in the country.
The Shinhwa Association is a separate organization built around keeping the Awakened world hidden from ordinary people while training new Awakeners. Ji-Yeong Yu leads it; AniList describes her as a highly ranked Awakened in her own right, responsible for teaching basic ability control to new arrivals. Her younger brother, Ji-Seok Yu, is credited as one of the most powerful teenage Awakeners in South Korea, with AniList noting only a handful of teenage Awakeners nationwide can rival him. Two more Shinhwa-affiliated names round out the circle: Bo-Yeong Choi, a friend of a character named Jae-Hyeok Lee who's sent to the Academy on the Association's behalf, described as cheerful but privately cunning; and Cheol-Yeong Im, an instructor at the Academy who also chaperones a student named Halla.
These two circles, the Academy and Shinhwa, aren't confirmed anywhere in AniList's data as the same organization. They overlap in purpose (training and protecting Awakened) without a stated command structure linking them, which is worth keeping straight rather than flattening into one generic "good guys" group.
For readers who came to this cast through Eleceed's setup rather than its fights, this site's manhwa like Eleceed list sorts seven similar picks by which piece of that hidden-power, mentor-and-student structure hooked you.
Rivals and Antagonists: Frame's Confirmed Executives
Frame is the organization AniList's character bios name most consistently as the source of Eleceed's conflict, and five of its members have enough documented biography to matter by name.
Muse, also credited under the alternate name Alpha, is a top-level Frame executive and disciple of a figure named Suffrey Basseterre. Roist holds a comparable senior position under someone named Schneider. He's also noted as the brother-in-law of a character called Duke, whom he reportedly dismisses as a lucky upstart rather than a real peer. Neither Muse nor Roist has an explicit numeric world ranking confirmed in the available bio text, worth flagging since three other Frame names do.
Morthius, subordinate to a figure named Greg, is confirmed by AniList as a member of the world's top 50 Awakened. Vatore carries the same top-50 confirmation and a specific personal grudge. AniList's bio states a past fight with Kayden left a scar across his face, and he's noted as being particularly proud of his appearance. Earthquake, also a top Frame executive, is likewise confirmed top 50. His AniList entry notes he's killed later in the story by a character named Kartein, one of the few character deaths this guide can confirm from bio data alone.
A sixth name sits adjacent to Frame's activity without being a confirmed member. Loberne, whose ability is Hypnosis, was tasked with retrieving a figure AniList calls Dr. Delein from an organization called the Awakened Union. Loberne is currently imprisoned as of his most recent confirmed status. Dr. Delein's own role isn't detailed enough in available bio text to state anything further. This guide stops at what's confirmed: the name exists, and Loberne was sent after her.
One more name here stands apart from the rest of Frame's roster. Amyeong, also credited as Dark or Rui, is described as an assassin and Kayden's former apprentice. AniList's bio adds a second detail that changes how both leads read: she's identified as Jiwoo's mother. It's the most specific family connection confirmed anywhere in the available character data, and it's not something either the review or the reading guide spells out directly.
Left to right: Muse, Vatore, and Earthquake. Vatore and Earthquake are each individually confirmed at world top-50 strength on AniList; Muse's rank isn't specified.
The World Ranking System: Top 10, Top 50, and Top 100
A detail that gets lost in most Eleceed summaries: the Awakened world runs on an explicit, tiered global ranking. It's separate from whatever rank a character holds inside their own school or organization.
Veramonte Patrick is the clearest Top 10 confirmation in AniList's data, described specifically as a top-10 world Awakened rather than merely powerful. Morthius, Vatore, and Earthquake are each independently confirmed at Top 50, all three tied to Frame specifically. That's a useful pattern on its own. Frame's confirmed muscle clusters in the world's second ranking tier, while its top executives (Muse, Roist) hold organizational seniority without a matching numeric rank in the bio data available.
Leah Eresby's top-10 standing is a different, smaller scale entirely. She's ranked in the top 10 of the World Awakened Academy specifically, a school-level distinction, not a claim about where she'd place against Veramonte Patrick or Frame's top-50 roster. Mixing up an Academy-internal rank with a world rank is an easy way to overstate a character's actual standing. It's a distinction AniList's bios are careful to keep separate.

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 400+ chapter run.
- Jiwoo Seo, from the opening chapters, established as a hidden-ability high schooler who quietly helps strangers and strays.
- Kayden Break, entering within the first handful of chapters once Jiwoo takes home the injured cat that turns out to be the world's strongest unaffiliated Awakened.
- The Awakened Academy circle (Garrith Luterain, Leah Eresby, Veramonte and Ian Patrick, Seong-Ik Han), surfacing as Jiwoo's world expands past his and Kayden's two-person dynamic.
- The Shinhwa Association (Ji-Yeong Yu, Ji-Seok Yu, Bo-Yeong Choi, Cheol-Yeong Im), entering as the organized side of Korean Awakened society becomes relevant to Jiwoo's training.
- Frame's confirmed executives (Muse, Roist, Morthius, Vatore, Earthquake), arriving as the story's antagonist pressure shifts from individual threats to an organized rival group.
- Loberne, tied to Frame's activity through his assignment to retrieve Dr. Delein.
- Amyeong, entering later with the assassin backstory and the Jiwoo's-mother reveal that recontextualizes Kayden's own history as a mentor.
That order follows the manhwa's own pacing logic (two-person dynamic, then Academy, then Shinhwa, then Frame) rather than an alphabetical wiki listing. A few of these names, Amyeong especially, land with more weight discovered in order than spoiled upfront.
Eleceed Character Guide: Tips for Tracking the Cast
Track this cast by organization first, ability second. Nearly every named Awakened here belongs to one of three circles: the Awakened Academy, the Shinhwa Association, or Frame. Knowing which circle a name belongs to tells you more about their likely role in a given scene than their power level does.
Don't assume every top-ranked character is equally dangerous to Jiwoo specifically. Veramonte Patrick's Top 10 world standing and Morthius, Vatore, and Earthquake's Top 50 status describe their standing against the entire Awakened world, not a guaranteed threat level against this specific cast at this specific point in the story. Power rankings in Eleceed describe reputation more than they predict outcomes.
Keep family and mentorship ties separate from organizational ties. Amyeong is both Kayden's former apprentice and, per AniList, Jiwoo's mother, two relationships that don't overlap with any Frame or Academy affiliation at all. Treating every relationship in this cast as organizational is how a personal reveal ends up read as a faction twist instead.

Common Character Mix-Ups
Advertisement
Jiwoo Seo and Jiwoo Choi are the same person. Choi is an incorrect surname that circulates in fan summaries, including two earlier pieces on this site. AniList and Wikipedia both confirm Seo.
Kayden Break and Kayden Week are also the same character. Week isn't confirmed anywhere in AniList's data; Break is the name on record, alongside the anagram alternate credit Casein Nitrate.
The Awakened Academy and the Shinhwa Association get treated as interchangeable in casual recaps because both train Awakened individuals. AniList's bios don't confirm one commands the other. Garrith Luterain runs the Academy; Ji-Yeong Yu runs Shinhwa. Keep them as two separate circles that happen to share a general purpose.
Veramonte Patrick's Top 10 world rank and Leah Eresby's top-10 Academy rank sound identical but describe different scales entirely, one worldwide, one school-specific. Conflating them overstates whichever character is being discussed.
Frequently Asked Questions
Who is Jiwoo Seo in Eleceed?
Jiwoo Seo is Eleceed's protagonist, a high schooler with cat-like reflexes and super speed who spends his free time secretly rescuing people and stray animals. AniList's character database and Wikipedia's Eleceed entry both credit him under the surname Seo, not Choi, which is the name several fan recaps still use.
Who is Kayden Break in Eleceed?
Kayden Break is the strongest unaffiliated Awakened in the world, stuck in the body of an overweight housecat after a mission went wrong. He trains Jiwoo in exchange for help navigating a body he can't fully control. AniList lists an alternate name, Casein Nitrate, an anagram of his real one.
Who are Eleceed's main antagonists?
Frame is the organization AniList's character bios name most consistently as a source of conflict. Its confirmed executives include Muse (also called Alpha), Roist, Morthius, Vatore, and Earthquake. Vatore and Earthquake are both individually confirmed at world top-50 strength, and Vatore is stated to hold a personal grudge against Kayden.
What is the Awakened ranking system in Eleceed?
AniList's bios describe a tiered world ranking for Awakened individuals: Top 10, Top 50, and Top 100, tracked separately from any single organization's internal ranks. Veramonte Patrick is confirmed Top 10 worldwide, while Morthius, Vatore, and Earthquake are each confirmed Top 50. Leah Eresby's top-10 standing is scoped to the World Awakened Academy specifically, a smaller, separate ranking.
Are Jiwoo and Kayden's names spelled differently elsewhere?
Yes, and it's a genuine, checkable error rather than a stylistic choice. A number of recaps, including two of this site's own earlier Eleceed pieces, use Jiwoo Choi and Kayden Week. AniList's character database and the dedicated Eleceed Wikipedia page both confirm the correct names are Jiwoo Seo and Kayden Break.
Is Amyeong related to Jiwoo or Kayden?
AniList's bio for Amyeong, also credited as Dark or Rui, describes her as an assassin who was once Kayden's apprentice and identifies her as Jiwoo's mother. It's one of the more specific family connections confirmed anywhere in the cast data.
Is this Eleceed character guide based on the manhwa or the anime?
The manhwa. Every name in this guide traces to AniList's character list for the Eleceed manga entry, media ID 106929, cross-checked against Wikipedia. The 2027 anime, produced by Dandelion Animation Studio, has only confirmed a handful of voice cast pairings so far, covered separately in this site's Eleceed anime release date article.
