Saike Mata Shite mo

A middle school student named Saike Kuzushiro, who is unambitious and introverted, experiences a road accident that results in the death of his childhood friend, Mikan Karatachi. After expressing his grief to God, Saike falls and awakens the previous morning, on the day of the accident. He is left questioning whether events will unfold as before and if he can prevent Mikan's death. He also wonders about the nature of the power that has allowed him to relive the day. A one-shot titled "The Negatibrain" is included in Volume 3.
