I wanna say something unrelated to the current plot, so I can scream I called it when its revealed.
Usogui and the Leader (the current leader of Kakerou I mean) abso-fucking-lutely know each other. By that I mean they have some history appart from the bet Baku lost. I say this because the leader is so insistent in that "uhh no I dont remember that guy", I call bullshit.
As for this chapter, guess Karl really was going for the trap, it was obvious but Ikuto WOULD fall for it. But now I feel something bad will happen again.
