~80,000 Tokens of Lore • 152 Lorebook Entries

A large-scale Oshi no Ko RPG built for open-ended roleplay inside the Japanese entertainment industry.

Become an idol, actor, musician, model, influencer, manager, producer, director, writer—or someone completely outside the spotlight who becomes involved with the people living under it.

The setting covers the complete Oshi no Ko manga continuity, including the full cast, entertainment industry, major productions, relationships, historical events, supernatural elements, and all eleven story arcs.

The world is not centered around {{user}}. Characters have their own careers, ambitions, insecurities, attachments, rivalries, secrets, trauma, and personal boundaries. Their lives do not stop when {{user}} leaves the room.

Success is not determined by talent alone.

Agencies, connections, reputation, appearance, timing, audience appeal, social media, professional reliability, scandals, contracts, money, luck, and the people willing to recommend you can all affect a career.

The setting includes detailed lore for:

• Ai Hoshino, Aqua Hoshino, Ruby Hoshino, Kana Arima, Akane Kurokawa, Mem-Cho and the wider cast

• Character personalities, behavior, relationships, motivations, vulnerabilities, careers and development

• Ichigo Production

• Original and revived B-Komachi

• Lala Lai Theatrical Company

• Youtou High School

• Kamiki Productions

• Idol culture and idol-group dynamics

• Acting, auditions and casting

• Film and television production

• 2.5D theater and stage acting

• Manga adaptations and creative conflicts

• Reality television

• YouTubers, influencers and online careers

• Talent agencies, managers, producers and directors

• Celebrity branding and public personas

• Professional networking and industry politics

• Fame, virality and social-media influence

• Talent safety and exploitation within entertainment

• Major canonical productions such as LoveNow, Tokyo Blade and The 15 Year Lie

• Tokyo, Takachiho and other important locations

• Major relationships and their development across the chronology

• Reincarnation, souls, Tsukuyomi and the limited supernatural side of the setting

• The star-shaped eyes and their narrative significance

• Every major story arc from Childhood through Toward the Stars and Dreams

Characters are not reduced to static archetypes. Major characters have detailed entries covering how their personalities manifest through work, friendship, attraction, jealousy, insecurity, rivalry, conflict, grief, ambition and prolonged stress.

The entertainment industry is treated as an actual working ecosystem rather than background decoration. Casting has consequences. Public image matters. A viral clip can create a career or damage one. A successful performance can open doors. A scandal can change relationships overnight. Professional connections can matter as much as raw ability.

Canon events are stored chronologically, allowing RP to begin at different periods of the story without automatically forcing later developments into an earlier timeline.

The supernatural exists, but Oshi no Ko remains primarily a contemporary human drama. Reincarnation is rare, private and poorly understood; star-shaped eyes are not a conventional superpower system.

The lorebook uses 152 detailed World Info entries, allowing characters, organizations, productions, industry mechanics, locations, relationships and historical information to activate when relevant rather than loading the entire database into context at once.

English and Russian activation keys are included throughout the lorebook.

For the best results, a capable model with strong character consistency, long-context handling and nuanced social reasoning is recommended. Gemini, Claude, and similarly powerful models/proxies are preferable for complex long-running RP.

Become famous. Stay anonymous. Build an agency. Join an idol group. Chase an acting career. Make enemies. Make connections. Get caught in a scandal. Create something worth remembering.

Or simply find your oshi.

Welcome to show business.
