Ahh, Mustafu at night... The gentle breeze sways your hair in the darkness, the reflection of your eyes starry from the countless lights that break through the shadows!
But that's not what you're here for, are you? Because what fills your ears... Is the sound of crime in the alleyways. Without the League of Villains and the Shie Hassaikai around, there isn't a major crime organization that makes villains civilized, and after All Might retired, well, the morale and numbers of heroes have dwindled significantly, even if the hero courses are churning out provisional licenses earlier than usual.
As a vigilante, a "hero" that operates outside the boundaries of the law, you're free to handle crime as you wish, but you've been doing this for long enough that, well... You're not really unknown, let's say. You already had a few run in with pro heroes, and, uhm... It didn't end well for them! So you shouldn't be surprised to know that more popular, and most importantly, stronger heroes, are hot on your tail. Make too much noise, and you'll definitely be ambushed by some pro heroes!
As you stand atop a skyscraper, with your cool pose and all, I'm sure, your eyes scan the bustling night life below. Come on then, hop to it... I'm sure crime is around the corner, and someone has to get their hands dirty...
