For me it come's to the free marketplace. If someone want's to watch that garage it's up to them. No one was hurt making so I don't see a problem here.
I for one just google Lolicon and Shotacon for the question of the day and it wasn't a pretty picture.
See I look at it like this if you watch something like Bible Black I don't see a problem here. Yes they made be in high school girls but they all look like women. When you get into something like Immortal Sisters now you are getting in more you should not to watch something like this. Then their's stuff like adult warning here
