Takayuki Furuichi has to take this one. He overreacts for some of the simplest things. A good example and my favorite line in the manga so far is when it said that Takayuki Furuichi ran like a bitch when Hilda and Aoi met after hilda lost her memory.
Being pervert he is always rejected and always overreacts everything that happens.
I guess i'll also go with Furuichi . He's indeed the character who likes to dramatize the most at about everything lol
