there's someone i need to protect

"Refugee? Tch… you obviously don’t know who you are talking to… Hmph. Byakuya Togami. Heir to the Togami Conglomerate… and humanity- hmph. There’s a laugh. Humanity is always suffering. Because idiots don’t know well enough not to get themselves killed.”

Well, you obviously don't know the hell people go through around here. An heir? If you're an heir, then why aren't you at your company? Surely the security there is good? I don't see why you'd want to go around a place like this so casually. 

"All I want to do is swing around on the maneuver gear."

Sadly, yes. It'd be too dangerous otherwise.

Like what?

Like..large human beings...only different. 4 meters and taller. They eat humans alive. 

"I won't leave you behind."

Hmm...an extremely long time of military training, learning how to work the maneuver gear, learning how to fight titans, fight humans, and get the best score you can.

Central Europe? What could possibly harm you out there?

There are monsters out there that I have to fight.

Its not my place to teach you how. If you'd like to learn, you could always sign up for the military and join the Military Police or Scouting Legion...but its a lot of hard work.
