Finished Koi Choco
Mifuyu's route - surprisingly normal. The anime doesn't really spoil anything at all and it felt nearly as much as a "boy meets girl" route as Satsuki's. Her loyalty to Chisato is truly something and this route makes her attitude in Isara's route a lot more sense. I still didn't like her in it, but I understood.
Michiru's route - the last and hands down the cutest route. Sadly, the big plot twist is completely ruined by the anime killing off any feels it could have otherwise easily generated. However due to the very little focus Michiru got in the anime it more than makes up for it. You learn a whole lot about her that the anime didn't even barely cover.
Final assessment: This game is amazing. No wonder it was adapted into a anime. And the anime for the most part stays true to the game, though it obvious mixed up events from the different routes but that's unavoidable. Chisato's presence as the main heroine is felt on all the other girls route to the point where you actually feel bad for NOT choosing her. The only downside to this game is the lack of routes for Ai, Kii, Non-chan (though she does apparently get one in the PSP version) and Hazuki with the biggest lost being from no Hazuki route. Now it's time to hope the PSP version gets translated as I hunt down a link for the game.
