サイケまたしても

Saike Kuzushiro, a reserved and unmotivated middle school student, lives a mundane life with his supportive childhood friend, Mikan Karatachi. After witnessing Mikan’s tragic accident, Saike, overwhelmed by despair, drowns in Mogura Pond and awakens with the ability to rewind time to the start of the day. Determined to save Mikan, he repeatedly relives the same day, using his newfound power to alter events. He encounters other ability users, including Eiji Hizu, who becomes an ally, and faces challenges from those seeking to exploit his time-looping ability. Saike’s journey transforms him from a passive loner into someone striving to protect others and find purpose. (Summary by Grok 3)
