Haruna Amo

Haruna Amo is the younger sister of protagonist Haruto Amo, and for six long years following Asahi's passing, she never stopped standing by his side as he struggled through grief. With her naturally bright disposition and keen emotional sensitivity, she consistently offered encouragement and warmth in their everyday lives, gently guiding Haruto back toward the world he had withdrawn from. Haruna serves as the invisible yet essential bond holding the siblings together, and the quiet driving force behind Haruto's gradual recovery.
