Chapter 11 : Genocider

Izuku : Vigilante ?

Toshinori : Yep. That's what i have been doing this whole time. 

Izuku : I see. So that is the way to slowly destroy this corrupted society. But why not go for a full on attack ?

Toshinori : Can't risk it. They may have something under their sleeves. An omnipotent weapon prehaps.

Izuku : That is true.

Toshinori : And by doing vigilante act, i can gather info about the hero quite easily. Though not everytime they will talk.

Izuku : That is indeed true.

Toshinori : Being a vigilante actually have alot of benefit. I can do what i want and raise my fame and relationship in the underworld. With that, i can recieve load of asset to various of things. Some even worth get your hands dirty on.

Izuku : I see.

Izuku and Toshinori is currently sitting in the cafe at midnight after everyone is asleep. Izuku is now thinking whenever he should be a vigilante or not.

Izuku : ... I think i'll become a vigilante.

Toshinori : Oh ok and i have a question about your quirk.

Izuku : Hmm ?

Toshinori : You nearly die once right ? You were slowly turning into nothingness but then how did you return ?

Izuku : ... I'll tell you what happen.

Flashback to when Izuku is slowly turning into nothingness.

Izuku : ... "I'll die like this ?... Tch, no way in hell i'll die like this... Move... MOVE !!!!!!!"

??? : You really are pathetic eh ?

Izuku : ... You are...

??? : Hello~... Me.

Izuku look at the voice and saw his younger self with a devilish smile.

Izuku : ... Of course it's you... What are you doing here ?

Y.Izuku : Isn't it obvious ? I can't let myself die can i ?

Izuku : Heh, your face is saying otherwise.

Y.Izuku : Hehhhh, but my face is like this because of you. I'm represent for your kindness and hatred. My face only show which side is overpowering the other side so it's normal for my face to look like this.

Izuku : I see... So what now ?

Y.Izuku : Well, i'll just show you your quirk true power. But be careful~. If you don't seal it carefully you might destroy every single world~.

Izuku : What do you mean by that ?

Y.Izuku : You know there are many world out there right ? Marvel, DC, SCP, WOD and a lot more.

Izuku : And ?

Y.Izuku : Idiot. If you just leave your power to let lose then those world will get destroyed because of the overwhelming power you produce.

Izuku : I see... So how many seal do i need ? There must be a correct amount right ?

Y.Izuku : There is. You need 72 seals to keep your power in check to be exact. Your power will be downgrade to low complex multiversal level but that is still enough. Now, let's awaken your true power.

Izuku : Ok.

Back to present.

Izuku : And after the awakening, my body reverse the effect of nothingness and fully heal immediately.
