Akuma no Riddle and now Yahari? I see, I see....

And yay. Everyone's totally going to get along~

Has he been soloing everything and going about killing hordes of people by himself? At 19 years of age? What exactly does he specialize in? Beating things up with his fists? Firearms? Knifefights? Is he a 'true' assassin, or is he more of a superhero who just lolrekts everything with no pretension of stealth? Gimme a bit of a description in regards to how extreme his training was.

Outside that, he sounds pretty...questionable. Even Hikari Ketsueki wasn't THIS brutal.

Now that I think about it, he sounds sorta like that emo dude from Mahouka as well.
