I get a kick out of how everyone in the military, allied or axis, is bisexual or gay. Everyone, even the nameless background characters. Miller is the only hetero for miles.
Micheal is hilariously shameless & has no problem with things like public sex & screaming about his love life to anyone within hearing distance. & his little brother Kurt has his own hilarious relationship where despite his age & stature, is exquisitely bossy & perverted. (Think Draco Malfoy crossed over with Shuichi from Gravitation & the little chicken hawk from Looney Tunes). I'm glad a large chunk of the manga revolves around him, because ukes like him are a refreshing change from the usual. This kid knows what he wants & goes for it whole hog.
A few of the many shenanigans in this manga; Hans becomes a priest, soldiers use his confessional as a dating service to pass love letters to enemy soldiers. Big hulking Micheal, who seemed like the manliest thing in the world, finds himself being hit on like a woman, which triggers Hans' berserk button, then they screw in a church.
This series also makes humorous use of "engaged in battle" as a double entendre. I got a little confused when Harunobu showed up, because the German officer he seduces looks quite a bit like Micheal until he takes his hat off.
This series is most likely set during WW2, but there are no swastikas & the soldiers are never referred to as Nazis.
An annoying translation error on the Scanlator's part is that they keep saying "English" when they should be saying "German."
Okay, you need to know that this is kind of a series, but all the books have different titles. Read them in this order:
*Koutetsu no Daitenshi.
*Datenshi ni Sasageru Uta.
*Daitenshi: Harem Nights (62 page official doujinshi).
*Datenshi ni Sasageru Uta: Family Visit (18 page official doujinshi).
*Doutei Saizensen.
*Bed no Shita no Himitsu.
