Emiya Shirou's Youth Has No Problems

I heard that anyone who uses a notebook as their cover is a big shot. Let's see if I can keep myself afloat.

I, Emiya Shirou, probably live in a gag manga world. My homeroom teacher, El-Melloi II, is unreliable, but that's not all. Rin Tohsaka, my club senior and president, is also a secret gag comedian. My childhood friend, a free-spirited, long-haired beauty with a huge bust, suddenly transfers back from overseas, and the first thing she does is start a wrestling club with her older sister... There's definitely something wrong with this world, right?
