Ep. 4: Sakuragi risks his life to save friends while confronting his past trauma and guilt.

Uncovered is shocked that Sakuragi would endanger himself for others, as he believes self-reliance is the only option. Sakuragi reaches the cell but cannot open the door as the building collapses, knocking him down with fire. Outside, Uncovered finds the key and refuses to give it to Ishihara. He enters the building to rescue Sakuragi and the others. After escaping, Sakuragi knocks out Ishihara. At the hospital, Sakuragi reveals his admiration for his soldier father, who returned from the war broken. Sakuragi once told his father he lost respect for him, after which his father committed suicide. Sakuragi feels responsible for this death because he failed to understand his father's pain. He vows not to lose anyone else, considering the other boys his best friends. This confession strengthens the bond among the seven.
