I think after some reflection this is my second favorite Uchikoshi game besides 999. I love what they did with the returning cast and every new cast member is awesome. The plot isn't as good as AI1 but it was still great, but I think the character writing more than makes up for it.
Also I don't know if 1 primed me for it or what but I minded the outrageously silly moments a lot less. I guess them
having an actual explanation for Mizuki being superhuman, as well as relying less on Porno mags as a power up device made it feel more grounded
