Ep. 23: Kusuo menghadapi masa lalunya yang tidak biasa melalui berbagai upaya perjalanan waktu ke kelas dua.

23

Kusuo attempts multiple time travels to back when he was in second grade and when a student named Takashi had bullied Touma but young Kusuo had helped Touma in many ways (healing his wound, causing Takashi to spin around a bar, and causing a classroom mess), leading to Touma's suspicion that Kusuo was a psychic. However, the attempts either do not change the present situation, or have a butterfly effect leading to a post-apocalyptic world. He relents and tells Touma that he is indeed a psychic, and Touma thanks him for all his help. (Source: Wikipedia)
