So, repeated visits to /k/ caused me to google this "Upotte!!" thing (and discover that surprisingly, all episodes were not torrented in the usual haven of buccaneers).
So, the characters are still in middle school/junior high (bearing in mind that the age of consent is 13 in Japan) but the Finnish exchange student is already a psychotic lesbian stalker with rapist tendencies who faps in the middle of a firefight WTF DID I JUST WATCH
Only in Japan...
So, since this is from the makers of Strike Witches and Girls und Panzer, when can we expect animuh featuring kawaii but mentally unstable warship girls from them?
