* GeniusBonus: The name ''Otto Carius'' can be read in the German textbook under Taki's words. He was a German tank commander during UsefulNotes/WorldWarII who reputedly destroyed more than 150 tanks. It's pretty cool, even if the world of the manga isn't the real world so...
* IronWoobie: Taki's situation is gut-wrenching and his devotion to his country and his people is really admirable.
* JerkAssWoobie: Klaus's own situation is NOT easy (deserts from his country for Taki's love, is subjected to racism in Taki's homeland, already had massive troubles before this happened), but it REALLY doesn't justify how he treats Taki. (i.e, In the anime he outright ''rapes'' Taki.)
* {{Moe}}: Taki in the [[BonusMaterial omake]]. [[CatGirl Cat ears and tail]], huge eyes, a frilly [[NakedApron apron]], getting molested by tentacles and acting all caring and worried about Klaus and [[ThroughHisStomach making him food]]... No wonder Klaus [[BlackComedyRape reacted]] the way he did.
