The currently documented Rain98 cast begins with Reina Amehara and the unnamed protagonist who shares her strange life in 1998 Tokyo. The public Demo contains other figures and voices as the story develops, but a trustworthy index should not assign names, relationships, or outcomes from a trailer cut or a discussion nickname alone.
This page stays spoiler-light and uses information exposed by the official Steam pages and public Demo premise. It treats “Angolmois” as Reina’s self-chosen identity, not a separate character.

The protagonist
Type: player viewpoint and Reina's companion.

The absence of a public name for the protagonist is meaningful. Use the term shown by the current build or “the protagonist” in general instructions. A custom name, localization choice, or preview author’s pronoun does not automatically become a universal canonical field.
Understand Reina without flattening her role
Official copy presents Reina as charming, mysterious, dangerous, and determined to see the world end. She shares a dark apartment with the protagonist, asks for help, travels through Shibuya, and participates in ordinary moments that contrast with the ritual. Her requests, reactions, and rare warmth are central to the player’s experience.
“Angolmois” connects to the apocalyptic identity she claims inside the story. It should appear as an alias on Reina’s card. Splitting the alias into its own biography creates a false extra cast member and separates a title from the person using it.
The Angel Passport gives the relationship a visible structure: special memories can produce stickers and move the ritual forward. That does not reduce Reina to a meter to maximize. Her dialogue, discomfort, boundaries, and scene context matter, and the public Demo does not publish a complete affection-value formula.
Read the protagonist as a viewpoint
The protagonist provides the player’s perspective on the shift from today’s Tokyo to 1998. Official descriptions focus on the shared days with Reina rather than supplying a full dossier. The uncertainty around how the time shift works, why the protagonist is present, and what the ritual will achieve belongs to the suspense.
For guide writing, describe actions rather than inventing personality. “The protagonist completes piecework” is supported by the playable loop. “The protagonist has a fixed profession, age, or secret power” requires explicit current evidence. Dialogue choices can express a response without proving one permanent personality across every branch.
Keep player identity and character identity separate. A Steam profile name, save-slot label, or player-selected response is not a cast fact. If the retail game later supplies a canonical name or profile, attach it to the base-game version and preserve the Demo-era record.
Use aliases and translations safely
When a localized version uses a different name order or transliteration, attach it as an alias with its language. Do not duplicate the entity. Voice actor Rio Tsuchiya belongs to Reina’s Japanese performance; it does not imply that every supported language has a separate full voice track. Steam lists full audio only for Japanese in the Demo language table.
Keep the cast index spoiler-safe
Character pages should answer the first useful questions—name, role, where the player meets them, product scope, and whether the information is official—before any chapter outcome. Put later revelations behind an explicit chapter warning. The Demo’s ending point in Chapter 2 is itself a scope boundary, not permission to reveal its final scene in an introductory card.
Avoid turning emotional or psychological interpretation into diagnosis. Rain98 contains difficult subjects and unsettling behavior, but an atmospheric description or a player’s reading does not establish a clinical fact. Use the developer’s mature-content notice and the scene’s own language.
Do not fill character gaps with extracted files, private test scripts, or hidden achievement names. Public availability of the Demo does not authorize material outside ordinary play and officially released media.
Resolve conflicting character claims
Start with the exact product and date. A 2025 or early-2026 show-floor build can establish that Reina appeared and that the Passport concept existed, while the October public Demo has greater weight for the playable order. An interview can explain design intent but cannot prove a secret revealed only in the finished story.
Next, separate a visible fact from an interpretation. A uniform, room, or line of dialogue can be described. Age, relationship, motive, and supernatural ability need a direct statement or an unambiguous scene. If two sources disagree, keep the field unresolved and tell the player which scopes conflict.
Finally, prefer a compact unknown over a speculative biography. Rain98 is designed around uncertainty, memory, and the line between reality and illusion. A correct character index should preserve those questions until the game answers them.
Continue with related context
Use the Angel Passport guide to understand the memory ritual without spoiling later character scenes. Use the Guides hub for a spoiler-light path through the public Demo, and Updates to learn when more Chapter 2 material becomes officially available.
The cast index will expand only when names and roles have direct public support. At present, Reina and the protagonist provide the reliable foundation: one central, named heroine with a documented alias and voice actor, and one deliberately under-defined viewpoint character transported into her rainy 1998 world.
