The lack of our main character just makes it so i can't wait to find out what he is doing.
I liked these past few chapters, they've been setting things up for a massive final confrontation. Shiro almost seems to have a sort of similar reason for his actions as Riku in that he sees Nene as a means to reuniting with a lost love.
Will be interesting to see if Nene really matures, becomes Amane and views Riku as a lover instead of the father Nene sees him as. Mostly though i just want to know what the hell happened with Amane in the past at the hospital.
