The hero that gets stronger after every fight

Chapter 2- First dungeon

Nurse: hey you know that patient named izuku yagi I heard that he's quirkless

Nurse 2: are you sure he seems to have healed fast from the sludge villain he's also been running every day even though he just got put in here

Nurse: the doctor said in his file he's quirkless but maybe he has a stamina quirk or something that got over looked

Nurse 2: look he's running now

Nurse: he looks out of breath are you sure he's got a stamina quirk wait how many hours has he been running. . .

Izuku's POV

It's been four days since I woke up there are a few things I found out. First, the blue panels I've been seeing isn't a hallucination from almost dying even though no one else but me can see it.

Izuku: accept status recovery

When he said this his whole body began to glow in a heavenly gold colour

Magic that can heal your fatigue after exercising the fatigue that was nested in my whole body actually disappears like it was never there to begin with

Aside from that there is also stat points and these random box items you can increase one of your character stats at will as long as you have the points for it. I get stronger as I increase my characters stats of course increasing my level would do the same. Status , skills , item inventory , item storage. It's like a game.

Izuku: haha what is actually happening here

——————————————
~Mini time skip~

Izuku: can I take a leave for today

Nurse: yeah that should be fine but where are you going

Izuku: I have some business to take care of outside

—————————
~Another mini time skip~

Izuku: alright let's see if this really works

The random box that I get every time I do a daily quest normally gives me some useless items like bandages and pens and stuff but this seems a little different. A key that can open a dungeon could all of this be my quirk

Imagine that everyone hearing that the weak and worthless deku finally got a quirk they'd all laugh

Izuku: I'm confident in my abilities and if it gets too hard I'll run I've had a load of practice doing that in my life

Izuku reaches out key in hand and holds it out in front of musutafu subway station entrance the key glowed gold and a blinding blue portal appeared in its place

So he walked in.

Notification: you've entered the instant dungeon

And with that the portal sealed itself off trapping him inside

Izuku: no way the entrance got blocked ( a person walked past) , huh can these people not see me I guess these dungeons are like a different dimension

Izuku: Damm what do I do now if things got bad I was planning on running but I guess I can't do that if the entrance is blocked now

Another notification popped up
You cannot leave the dungeon either until the boss is defeated or you use a return crystal

Izuku: of course , you've got to be kidding me how the hell am I going to do this. . .

———————————————

As he adventured deeper down into the dungeon that eerie feeling and nervousness never left him every nerve in his body felt like it was on edge, his plan thwarted he could no longer run but what if he died here no one would be able to find his body he'd die alone, but I guess it's not the first time he almost died alone.
