Seishun Morishita is a student, an aspiring hero unlike his villainous siblings. The final child of the third greatest hero, he is the only light of his siblings' dark, cold worlds:

One, an S class criminal.

The other, a confused little girl.

Eager to bear the good news within the dysfunctional family, he attempts to join Yuuei. However, it soon seems, it's not his lucky day. Seishun is given a chance, an exchange student spot. Because, well, to tell the truth, Izuku isn't at school a lot.

Join Midoriya and the gang on a new adventure after their recent Mafia mission and learn the cold truth that lies behind, Seishun's strange submission.
