Inei Hoshi, a college sophomore and talented basketball player, chooses silence over speech — a decision rooted in a past heartbreak that still echoes through his quiet life. When a spirited classmate named Azami reaches out to him, she drags Inei into a circle of friends whose names — Chura, Aneko, Yui, and Yasu — mirror the stages of grief themselves.

As Inei bonds with each of them, their personalities begin to reflect the emotional storms within him. What starts as a lighthearted college rom-com spirals into a deep battle for control — of his emotions, his past, and eventually, his reality.

But when Inei’s ex-girlfriend Rina reappears, his silence shatters. Their reunion rekindles old wounds and awakens new powers — martial arts fused with elemental energy, where emotion fuels strength. Torn between the ice of regret and the lightning of anger, Inei must confront Azami’s hidden motives and his own fractured heart.
