But yeh it's rather safe, since it's not that kind of anime, tough when l was at home l never had a problem even watching Chobits or the like (back then) more so, my sister always said it's pure porn, but somehow she was somplace watching it as well, shes plain stupid, l dunno, maybe fathers genes, l dunno, or maybe they swapped her in the hospital (please) and my mom always liked watching anime l brought or DLed (ofc not hentai, she never even seen any lol) so l guess l was blessed with some understanding at home, now l can watch even in the bath on my lappy, since l live alone (ocasionally with my gf)
