Souta Mizushino is a high school student who dreams of becoming a creator, yet is consumed by guilt after his friend Setsuna Shimazaki takes her own life—a tragedy he partly blames himself for due to a moment of jealousy. Trapped in a cycle of avoidance and inner turmoil, Souta gradually finds himself at the crossroads of reality and fiction. Through a long and painful journey of self-confrontation, he ultimately reclaims his identity as a creator, masterminding a crucial operation that reunites Setsuna with Altair across dimensional boundaries and prevents the annihilation of the world.
