Gate - Thus the JSDF Fought There!

Yeah its harem that involve dark elf, elf , some 900+ y.o loli apostle and loli expressionless nomad mage .. somethin like that

But dont worry it has very good story not just some panties seeking pervert 

I am watching the anime and it doesn't look like a harem, more like they are in love with him, but he is just otaku, he likes them and all, but he never does anything about that. It's like he thinks they are pretty, etc, but he still prefers mangas 

This isn't really a harem. It's just about a guy who has adventures in a fantasy world basically.
