Lol, it certainly is.
Just finished playing every route. After finishing every route, you will unlock a "Kyouichi(Kaito)'s mode". And its awesome. Kaito definitely is the best.

Spoiler for His route:

I have to say that Ren(the cute pink hair girl who is always with Kaito) is just too adorable! She's the heroine of his route(though no h-scene), and her actions is too priceless. The heroines in the main routes cant be compared to her.

Also, Kaito not only had a child with Tae, but he also had a flashback of what it appears to be Reika's last moment..... I was so sad.....
