ANOMALITH Game Main Characters and Voice Cast

ANOMALITH's main characters are Reona Minazuki, the 17-year-old Diver you play, her missing best friend Arisa Kato, and the staff of the government's Anomaly Zone Countermeasures Office: Yuiga Koda, Kyoka Sudo, Imari Fushimi and May Hibiya. Two further figures, Kaede Mori and an unnamed girl, sit outside the organisation.

Reona Minazuki

Reona is the protagonist: seventeen, a Diver for the Anomaly Zone Countermeasures Office, and the only survivor of her first mission. She joins the organisation to find Arisa, who vanished when a shopping mall turned into an Anomaly Zone.

Her backstory is deliberately bleak. She left a difficult home and was living on the streets when she met Arisa, and the friendship became the thing she rebuilt a life around. The game keeps the circumstances of her survival hidden behind a redacted block of text, which is the story's central mystery rather than a marketing tease.

Arisa Kato

Arisa is the friend the entire game is chasing. She and Reona met while Reona was homeless, became close despite coming from different backgrounds, and were separated when the mall they were visiting anomalised.

She is a presence rather than a party member: the story is structured around Reona's search, and Arisa's whereabouts are the thread that pulls the campaign forward. The marketing keeps her out of frame: she is the reason Reona dives, not a companion in the field.

Yuiga Koda

Yuiga is the Office's operator and Reona's remote support during a dive. She is the voice in the earpiece: the character who warns you about approaching Anomalies, calls out objectives and keeps the mission structure legible.

In a game with no co-op partner, the operator carries the role a second player would normally fill — not as a participant, but as the person reacting to what you do.

Kyoka Sudo

Kyoka founded the Anomaly Zone Countermeasures Office and runs it. Before that she was lost inside an Anomaly Zone for an extended period and walked out alive on her own, which is the credential that makes her the person sending other people in.

She is the authority figure in the story, and the one most likely to know more than she says — a standard shape for this genre, but one the game leans on deliberately.

Imari Fushimi and May Hibiya

Imari heads research and development. She turns the anomalous objects you retrieve into weapons and gear, which makes her the in-fiction explanation for the upgrade systems you use between dives.

May heads security. She was an elite Diver before moving behind a desk, and she now controls access to anomalous objects and the classified material around the zones. Where Imari explains your equipment, May explains what you are not being told.

Kaede Mori and the girl

Kaede is a mysterious figure Reona meets during a dive. Beyond that, the official material gives nothing away, which is presumably the point.

The unnamed girl briefly accompanies Reona and Arisa on the day the mall anomalised. She stopped speaking after watching her parents killed by Anomalies, and she is the story's clearest link between the personal and the cosmic halves of the plot.

Voice cast

Japanese is the only full-audio language listed on Steam, with Korean also carrying full audio support. English, Simplified Chinese and Traditional Chinese are subtitled rather than dubbed.

Who designed them

Character design is by MON, whose previous work includes the Nisio Isin Legends series. Scenario is by Romeo Tanaka, known for Humanity Has Declined and Stella of the End. Music is by Yuka Kitamura, whose credits include Elden Ring, Bloodborne, Sekiro and Dark Souls III.

That combination is the reason the game got attention before anyone played it: a light-novel-adjacent writer, an illustrator with a distinct style and a composer associated with FromSoftware is an unusual trio for a mid-budget survival shooter.

Who you actually spend time with

Most of the campaign is you and Reona, alone in a zone. The supporting cast lives at the base and in your ear: Yuiga as the operator, Kyoka as the chief who sends you out, Imari behind the equipment bench and May behind the locked door.

That structure matters for how the story lands. The relationships develop between dives rather than during them, which is why the reports and side missions carry so much of the character work.

Spoiler boundaries

Everything on this page comes from published character profiles: names, roles and voice actors. Nothing here reveals what happens to Arisa, what Reona's redacted survival actually was, or how the story ends.

If you want to go in clean, the demo covers the premise and stops there. The character profiles are safe to read; a wiki plot summary is not.

What the cast tells you about the tone

Seven named characters, one of whom is a child who has stopped speaking, is not a light cast. The premise — a mall full of people turned into Anomalies, a friend missing inside it — sets a grim register that the Showa-era nostalgia deliberately undercuts.

That combination is the game's identity: warm, familiar environments doing something wrong. The cast is built to make the wrongness personal rather than abstract.

How the cast is introduced in-game

Reona is the only character you control. Everyone else arrives through the base and through the radio: Yuiga during a dive, Kyoka and the rest between them, and the reports in between.

That means the cast is built for short, repeated contact rather than long scenes. Characters accumulate through side missions and report text more than through cutscenes, which is a deliberate choice for a game about being alone in a zone.

If you are deciding whether the story will hold you, the demo shows the structure but not the payoff. The character profiles here are the safe way to learn who matters before you play.

One line on the cast

Seven named characters, one silent child and a protagonist who spends most of the game alone. If that sounds thin, the reports and side missions are where the cast actually lives — the profiles here are the map, not the story.
