An Explosive New World (Bnha x KonoSuba)

Afterlife

The truest of Heroes are always sacrificing their lives for people they don't know. Their bodies always move before they can think. No matter what happens to them, they must protect the ones they are trying to save no matter what.

Even if it takes their life.

Shigaraki shooting black and red claw-like tendrils at Endeavor. Piercing through the Number one hero's body and forcefully activating his quirk. Showing the now charred human being that resembles nothing like a human at this point. That slowly emerges from the flames of Endeavor, and twisting his head towards the green-haired teen whose's arms are completely messed up.

More tendrils starting to immerge from the burnt villain, all of his attention was on the One for All quirk user. The most important thing about this war was taking the Quirk from the boy and finishing every last hero with a hero with it.

Shigaraki was pretty surprised to see that the boy had energy left in him. He was beating the shit out of Shigaraki after he nearly killed that old man that was always near All Might and presuming was told that his Grandma was close to him as well and the former wielder of One for All.

At this point, Shigaraki wanted to end this whole fight right here. The black and red tendrils shot at Izuku, the poor boy could do nothing. The teen doesn't have any new tricks, he could use float but it's too late, the tendrils are coming at him fast like a bullet. OFA is going to be taken if he doesn't do something quick.

Slowly raising his destroyed arm and his hands ready to flick the tendrils always. But one person sees this, an angry explosive blond.

Katsuki Bakugou

Watching his former child friend slowly about to be impaled by those tendrils. Memories started to flood the teen's mind, memories of Izuku always there telling him how cool he is to help him when he fell. The moment when Katsuki started to hate Izuku for 'looking down on him' More memories came, when he captured by the slime villain and when Izuku told him that his body moved on his own and he couldn't watch him die

Katsuki's eyes widen, this was like the slime villain, without thinking his body moved on his own. His hands rocketing explosions, moving as fast as he can. His heart was pumping so fast that he could have gotten a heart attack.

Katsuki was a couple of feet away from Izuku, the tendrils almost about to hit the poor teen. More memories flash through the blond teen's head once again. This time is when Izuku got into U.A., all the times he has gotten stronger, all the times he got past Katsuki, the time when Izuku told him his biggest secret how he obtains his quirk. The time Katsuki felt vulnerable for the first time when he thought he was the reason All Might retired and can't use his quirk anymore.

The times they had to fight villains together like on I-island or when they had to fight those four villains on an island with no licensed Heroes around.

All of these memories showing to Katsuki how much the friend he knew since his childhood. The person who he bullied for a decade. The person that made him push himself to his limits. Someone, he would never think in a million years that his pride that was stuck up his ass that he couldn't see that Izuku was a friend. A real friend, not a follower who just cares about popularity, but cares about their friend's feelings. Someone who really cared about them and was there for him, but Katsuki would push him down, but he would right back up.

Katsuki was alright what outcome that comes from this. The most important thing Katsuki wants to do is save his friend and make his friend's dream come true.

Izuku felt some kind of force shoving him away. At first, he thought it was float again, but what he saw was soul-crushing. His childhood friend, the person he looked up to was impaled by the tendrils.
