When life gives Ryohei a lemon, he will punch it with every strength he had while screaming "EXTREME!" at the top of his lungs.

Because according to Ryohei, an extreme man would always go straight and punch away everything that comes in his path.

Even if it meant having lemon juice to be sprayed all over until it hit his eyes, causing him to yell "EXTREME!" in pain.

And getting an earful from his sister afterwards.
