This anime was perfect, and I know the word perfect is a little bland so ill go in a bit more with the detail.
From episode 1 I was hooked, anyone here knows what I'm talking about. Now I'm a big fan of art in anime and the character design, background detail etc, and the way they designed the anime with red line instead of black was very interesting at least to me. Anyway onto the actual plot. What can I say, cute, genius, loli imoto? Ive already heard enough but when you add an exciting protagonist(shiro) who leaves you on the edge of your seat every time he so much as breathes and he's someone who came in this mystical new world and did nothing but dominate these people at not only their own game but their own lives.
