The game's protagonist comes from a fascinating background. Koishi is a satori—a youkai with the innate ability to read minds—who originally appeared as the extra boss of Touhou 11: Subterranean Animism . However, realizing her power made her hated, she made the extreme decision to close her "third eye" and shut off her own heart. This action sealed away her ability to read the minds of others but also made her own presence extremely faint. In essence, "Koishi is a contradictory character, born as a character without character traits".

For lore enthusiasts, this encounter stands out as a deeply respectful homage to her complex character origins. To help tailor future boss guides for your run, tell me:
