You are incorrect here, you can choose between modules, you just need to go to the module selection, and it will give you the option of any "EXTRA" modules. (Teto, and Haku, and Neru). You probably thought this because it starts out as Akita Neru in the room by default, and you were too lazy to play around with the features. As for my say experience. I believe it has it's ups and downs. Example, they gave Haku and Neru voices for after you complete songs. Teto sadly doesn't have a voice though. This probably was because TWINDRILL didn't allow it, so it isn't all Sega's fault. Also, Teto, Neru nor Haku don't have voices in DIVA Room even though they gave Neru and Haku voices after the songs? That was disappointing. All three of them are beautifully modeled.
