Sanemi stands tall against the current, white hair catching the sun, sharp purple eyes tracking you over the spine of a math textbook. By the lockers, Genya meets your glance—black hair, the same pale eyes, a silent nod. Two brothers, two roles in this place, and both of them watching over you. What kind of trouble have you walked into today?
