Miori Kurahashi, a popular and socially adept high school student, balances academic curiosity with athleticism, reflecting her dual intellectual and active nature. Her pink hair and cyan eyes frame a petite 160 cm frame with measurements of 85-56-86 cm, while her blood type B hints at a personality both passionate and independent. As Hisashi Yoshizumi’s classmate and close friend to Ikuko Yoshihara, she bridges social groups, a role echoed in her surname’s meaning ("storehouse" and "bridge") and her given name’s roots ("beautiful weave").

Her life shifts after an intimate encounter with Hisashi triggers a brainwashing device, warping her perception to view him as both romantic partner and cherished brother. This manipulation amplifies primal desires like lust without eroding her core affection, leaving her genuine feelings intact beneath the artificial overlay. Meanwhile, her younger sister Haruru independently nurtures her own crush on Hisashi, adding quiet complexity to their dynamics.

Miori’s story avoids overt conflict, focusing instead on untangling layered relationships—particularly her entwined bond with Hisashi—and navigating the fallout of external forces reshaping her emotions. Her journey explores the interplay between altered perceptions and enduring connections, all while maintaining her role as a unifying presence among peers.
