The Mimic characters list: every protagonist and key figure

Browse The Mimic characters list across all four books, comparing Yasu Masashige, Hiachi, Isamu Uchiumi, Shoin Kusunoki, and major supporting cast.

The Mimic characters list identifies the protagonists, playable figures, and major supporting roles across the four-book story, making it a useful reference for tracking the cast as each installment changes focus. Comparing characters book by book also clarifies which figures remain central, which are restricted by Story Mode, and which become important only through later revelations. Yasu Masashige, for example, is best understood in relation to the shifting conflicts rather than as an isolated profile, while the playable cast changes across the four books. Because some identities and alliances function as spoilers, reviewing the roster by book lets readers separate confirmed character information from story-specific developments before starting.

The Mimic characters list overview

The Mimic features a rotating cast of protagonists across its four books, with Yasu Masashige serving as the central figure of the opening story. Book One centers on Yasu and his classmates, while later books introduce new playable perspectives such as Hiachi and Isamu Uchiumi. Knowing which role leads each section helps players separate major characters from temporary classmates, teachers, suspects, and creatures.

The most reliable Book One roster comes from the Control’s Book character listing maintained by the community wiki. It identifies Yasu Masashige, Hiachi, Futaomote, Keiko Masashige, Shizu, and Biwaki as the canonical starting cast. Because later installments add and replace characters, this Book One list should be treated as a foundation rather than a complete four-book encyclopedia.

Later booksIsamu Uchiumi, Shoin KusunokiNew perspectives and escalating conflicts
Supporting rolesKeiko Masashige, Shizu, BiwakiFamily, classmates, witnesses, and connections
CreaturesVarious mimics and entitiesThreats encountered during investigation

A practical character guide starts by asking three questions: Who leads the current story, which supporting characters return across the four-book sequence, and how each figure functions in the school-based mystery? For example, Yasu Masashige anchors Book One, while Hiachi, Futaomote, Keiko Masashige, Shizu, and Biwaki help define its classroom and witness connections; later perspectives such as Isamu Uchiumi and Shoin Kusunoki shift attention toward new conflicts. Comparing these roles prevents a Book One appearance from being mistaken for evidence that a character is a permanent central protagonist in the broader The Mimic cast.

  • Does the figure drive the current book’s mystery? Protagonists receive major choices, revelations, and story focus.

  • Does the figure return across books? A returning character may provide continuity even when another player takes the lead.

  • Is the figure a person, suspect, or creature? This distinction matters because a complete The Mimic all characters overview includes both human roles and supernatural entities.

The four-book structure also matters. Readers who want the correct reading order can consult the overview of all four books and their sequence before comparing character arcs. Without that context, an early character may appear minor even when later books give that person greater significance.

The Mimic main characters and playable perspectives

The Mimic main characters are not controlled through a conventional roster-selection screen in the same way as many role-playing games. Instead, the experience presents story chapters through designated viewpoints, making the cast feel like a sequence of connected protagonist-led cases. The playable role changes by book, and Yasu remains the clearest entry point for new players.

Yasu Masashige appears to occupy the role of a student confronting strange events within and around his school. His position lets the story introduce the central mystery through an ordinary school environment before expanding into darker circumstances. Understanding Yasu’s importance is therefore more useful than asking simply who can be selected in a menu.

Yasu Masashige and Hiachi

Yasu is the anchor of the opening cast. The community Book One roster places him first, which supports treating him as the initial protagonist and narrative point of departure. His family connection, Keiko Masashige, also shows that the story is not limited to classroom encounters; relationships extend into a wider web of people connected to the central mystery.

Hiachi is the next most consequential Book One figure. Rather than treating him as a minor classmate, players should recognize that his presence links Yasu’s perspective to another major part of the first story. The pairing of Yasu’s central role and Hiachi’s expanding influence gives Book One its basic narrative structure.

Isamu Uchiumi and Shoin Kusunoki

Isamu Uchiumi and Shoin Kusunoki represent the strongest later-book additions to the character lineup. Their value lies in giving the story new centers of gravity rather than merely expanding the cast with more classmates. This distinction matters when comparing The Mimic playable characters, because each protagonist exposes different evidence, relationships, and consequences.

Players who prefer to understand the narrative structure before selecting viewpoints can use the chapter walkthrough and story sequence as a companion. It helps determine when the focus shifts away from Yasu and whether a character’s absence from the opening book is intentional.

Book One supporting cast and relationships

The supporting cast in Book One gives its school mystery much of its emotional and investigative weight. Futaomote, Keiko Masashige, Shizu, and Biwaki are the four figures named alongside Yasu and Hiachi in the community’s canonical starting list. Their relationships can be compared by the role each appears to serve in the story.

Supporting characterApparent connectionLikely narrative functionBest way to track the role
FutaomoteClose to Yasu’s school circlePeer who grounds the main groupWatch for shared reactions and private conversations
Keiko MasashigeConnected to Yasu’s familyPersonalizes the central mysteryNote how Yasu reacts to family-related developments
ShizuPart of the school communitySupports group interactions and information flowObserve who speaks with Shizu and when
BiwakiLinked to the early castAdds another perspective to unfolding eventsTrack Biwaki’s decisions and access to information

These roles should be described cautiously. The available community data verifies the names and their presence in Book One, but it does not establish every character’s exact occupation, alignment, or hidden allegiance. Apparent connection and likely narrative function are therefore interpretive labels based on their placement in the story, not confirmed mechanical claims.

Futaomote is especially important to track because his proximity to Yasu can make him seem like a stable ally. Shizu and Biwaki are more useful as relationship markers: their conversations may reveal how information travels through the group. Keiko’s family connection adds a different dimension because any event involving her changes the central protagonist’s personal stakes rather than merely advancing the school-wide plot.

A character-focused playthrough can record three details for every major role: Futaomote, Keiko Masashige, Shizu, and Biwaki should each be logged against Book One appearances, direct conversations, and access to separate locations. This creates a clearer comparison than a simple The Mimic all characters list—for example, Futaomote can be tagged whenever he speaks near Yasu Masashige and Hiachi, while Shizu or Biwaki can be marked whenever a scene suggests they learned something before the main group. Those entries help distinguish apparent connection from likely narrative function without presenting an uncertain allegiance as a confirmed fact.

  1. First appearance: where the character enters the narrative and who already knows their name.

  2. Private connection: whether the character interacts with Yasu, Hiachi, or another protagonist away from the main group.

  3. Information access: which locations and conversations the character seems able to reach.

For environmental context that helps interpret these encounters, the location guide covering the game’s schools and other maps is especially relevant. Knowing whether a conversation happens in a classroom, hallway, or off-campus setting can change how a character’s role is understood.

The Mimic story characters across the four books

The Mimic story characters divide into three broad camps: viewpoint leaders, supporting humans, and nonhuman threats. This framework makes the broader cast easier to remember because a character’s category often predicts what they can contribute. It also prevents entity names from being confused with major human protagonists when players revisit earlier chapters.

Character groupExamplesNarrative purposeSpoiler consideration
Viewpoint leadersYasu Masashige, Hiachi, Isamu Uchiumi, Shoin KusunokiCarry major chapters and personal stakesBook order determines when each becomes central
Supporting humansFutaomote, Keiko Masashige, Shizu, BiwakiProvide relationships, motives, and witnessesTheir motives may become clearer later
Mimic entitiesBook-specific creatures and threatsCreate danger and shape investigationsAppearance details may reveal future information

This division is especially helpful when tracking The Mimic all characters without following every minor mention from the beginning. Viewpoint leaders receive the most direct attention, supporting humans often reveal how information moves through a group, and creatures demonstrate how each book interprets the central supernatural threat.

The books also appear to vary in setting, which affects how character information is presented. A school-centered opening can support conversations between students and staff, while a later environment may provide more physical obstacles and isolated encounters. Readers should therefore connect the book-by-book progression guide with this character list instead of assuming every role receives equal screen time.

Community reports should also be treated as provisional when they concern identities or relationships that emerge after major reveals. Names are reliable when listed by the community roster, but interpretation of hidden motives can change as more story becomes accessible. Character identity is confirmed roster data; motive interpretations remain contextual until the relevant narrative reveals them.

A practical The Mimic character guide by play priority

Choosing whom to prioritize depends on whether a player values the opening mystery, later protagonist perspectives, relationships, or survival. The following guide organizes the cast by practical reading priority rather than ranking popularity. That approach avoids treating a major protagonist as less important merely because fewer scenes feature them.

Player priorityStart withThen followBest reason

Understand school relationshipsShizu, BiwakiFutaomote, HiachiMap how information passes through the cast
Prepare for creature encountersBook-specific entitiesCurrent-book protagonistsLearn which threats matter in each installment

For the safest first playthrough, focus on Yasu and the named Book One supporting cast. Delay detailed comparisons involving Isamu and Shoin until the narrative reaches their books, because spoilers can alter whether a first appearance seems insignificant. Readers focused on a complete roster can record names without researching each character’s fate in advance.

A second playthrough offers a different objective. Instead of following revelations chronologically, look for information that the first viewpoint could not access. Compare how Hiachi’s proximity to Yasu changes when seen from another protagonist’s perspective, and note which supporting characters appear only when trust, suspicion, or location shifts.

Creatures also deserve separate attention. The encyclopedia of monsters and mimic entities can help distinguish recurring enemies from book-specific threats. However, an entity should not be added to the list of main human characters just because it appears frequently. In The Mimic, threats shape the route of a protagonist, while characters shape the choices and relationships behind that route.

Frequently Asked Questions

Who is the main protagonist in The Mimic?

Yasu Masashige is the principal protagonist of the opening book and the clearest starting point for the story. The community’s Book One roster places him alongside Hiachi and the main supporting cast, while later books introduce other principal perspectives. Yasu should therefore be understood as the initial viewpoint, not necessarily the only playable lead across all four books.

How many playable characters are in The Mimic?

The Mimic uses several protagonist or viewpoint characters rather than one selectable character. Yasu Masashige leads the opening story, Hiachi is another major Book One figure, and Isamu Uchiumi and Shoin Kusunoki carry later perspectives. The most defensible count comes from the current book structure, since additional viewpoint roles may depend on game updates or story segmentation.

Are Futaomote, Shizu, and Biwaki playable?

Community Book One data identifies Futaomote, Shizu, and Biwaki as supporting characters rather than the principal viewpoint leads. They remain important because their conversations and relationships can expose information that Yasu and Hiachi do not initially share. Their presence in the roster should not be interpreted as proof that every named character can be directly controlled.

Does The Mimic Yasu Masashige story reveal more characters?

Yasu’s story introduces the initial school-centered network, including Keiko Masashige, Futaomote, Shizu, and Biwaki. Later chapters and books expand the cast with Isamu Uchiumi, Shoin Kusunoki, additional supporting figures, and entities. Because revelations can change the apparent importance of early characters, a spoiler-light character guide should focus first on the Book One roster.

Where can I find a complete character roster?

The most detailed starting roster currently available is the community-maintained Control’s Book characters page, which lists Yasu, Hiachi, Futaomote, Keiko, Shizu, and Biwaki. For later protagonists and book-specific figures, combine that list with the four-book sequence and the relevant chapter coverage, since the early roster does not represent every character in The Mimic all characters.
