I'm gonna be quick, don't watch it. I'm just writing a review seeing how high people rate this.
Story :
There is a war and that's pretty much it. Some dude r*pe another and at the end they kiss. I know in 2 episodes you have to be very quick but this is just bad.
Art :
They looked bad. The argument of it being old isn't one. I think they put some effort only in the r*pe scenes.
Sound :
Generic and bland. The H-scenes weren't hot because of its context and the seiyuu sounded like they didn't care.
Character :
Big blond german looking guy r*pes tough on the outside, fragile on the inside asian looking guy. Oh and the german guy is a softie at heart. That's all. I didn't understand these characters nor their actions. Like they kiss at the end but dude he r*ped you twice because he was angry.
Enjoyement :
It's more of a horror anime that it is Bl. It's wasn't the dumb fun of Papa to Kiss, it was only pain.
Overall :
Don't.
