窓川 芹香

The Enigmatic Student from Another School

An intriguing student whom Arata met from a different school during the daily train commute. With a mischievous and playful personality, Serika takes delight in playfully teasing others. Her intelligence and quick wit make it a formidable challenge for Arata to gain the upper hand in their interactions.

"Oh my, are you blushing?"

Point: At the mercy of her sadistic tease
Going home style: Commuting by train. Attending different schools limits their opportunities for contact, with their encounters primarily occurring during their shared train commute.
