To remember the past, and to keep going on (My Hero Academia Fan fiction)

Bakugou Katsuki remembers all his lifetimes. Each of them is different the last, but there are a few constants. The first is that he always meets Midoriya Izuku first, different names or otherwise. The second is that afterwards they meet the rest of the class members. The third is that their mentor is always an important hero or helper who is slowly dying or losing power. The fourth is that they all change the world. And the last is that he always remembers everyone, even though they always forget him.
