With her madness at its peak, Rena holds her friends and schoolmates hostage and threatens to kill them all with a homemade bomb planted on the roof of the school. Working together with the police and his friends, Keiichi defuses the bomb. Keiichi and Rena have a final confrontation on the roof, Keiichi armed with Satoshi's bat and Rena with her cleaver. Rena gradually regains her sanity until she defeats Keiichi, though she is unable to bring herself to kill him. Rena reconciles with her friends. Though tragedy has been averted through Rena's atonement, the constant time loops have yet to lift; however, there is now hope for the future. (Source: Wikipedia)
