Well, as you can see. I kinda like characters like Rikuo when they have split personalities one at night and the day xD So, if you guys like something like that you should really read this because that is kinda the whole purpose of this manga but not exactly the whole purpose but for me it is. Dun worry ^_^ there is a storyline in it so chill, this is not onlu related to psychological problem or stuff xP
And I have rewatch the anime three times, so trust me. ;)
