Tiny Summons, Ferocious and Adorable!

A nobody whose soul has transmigrated grows stronger little by little through one life-or-death battle after another, thanks to a fusion-summoning ability that can get him killed at any moment. He has loved and laughed, and he has cried, too. By the time he is covered in honors, he looks back and finds himself beyond the Three Realms. His former ambition to reach the very pinnacle of power has long since become a thing of the past. What does it mean to be the strongest? Just watch me show off, and you'll find out.
