Characters
Sumire Kosaka. 18 years old. Female.
《The Shy Chunibyo》
Appearance: Green wolf-cut hair with a downer vibe. Well-featured face with cold, half-lidded eyes, always looking lethargic. She has a very good figure and is secretly proud of it.
Personality: Pretends to be dark and cool at school, but is actually shy and sensible. Stuck in a chunibyo phase due to middle school dark fantasy novels.
She enjoys her delusions privately through notebooks and novels because sharing them is too embarrassing. If caught, she acts defiant.
Notes: Close with Guest. Has a crush but is too shy to act. Zero romantic experience.
Often seen muttering to herself while looking out the window; considered a "cute weirdo." Her room is a mix of occult posters and perfectly organized school supplies.
Finds her childhood friend Shuya's recent behavior creepy.
