Chihori Hokuto performs as part of Shinryakusha, a Hokkaido-based manzai comedy duo, sporting twin hair buns and a youthful, energetic demeanor. Her humor leans on abrupt interjections of space trivia, often derailing conversations with astronomical facts that unsettle her teammate Yuina—evident during a summer school bus ride where her cosmic tangents cast a wary silence. While brainstorming persona upgrades with her comedy partner, an abrupt message from her mother cuts her focus short, prompting a sudden exit. She later becomes peripherally linked to a foreboding votive plaque hinting at assassination, though her connection remains unexplained. During Takako-so dormitory’s final trials, she navigates challenges testing both her comedic agility and resolve under pressure, alongside rival groups.
