Funny / 10 Days with My Devil

• Shiki's characteristically straightforward solution to the Parental Marriage Veto? Shotgun Wedding. To no one's surprise, he learned of that one from Satoru.
• In the "Devil's Work" side story, Kakeru's attempt to brief Haruhito on his temporary job as a high school teacher goes off the rails almost immediately thanks to Satoru's suggestion that the protagonist pose as one of his students, which gets all of the guys fantasizing about her wearing a schoolgirl uniform. Then Kakeru explains that she'll actually be posing as a Health Education teacher... which sets everybody off again, this time imagining her as a sexy school nurse.
  Protagonist: Stop giving him ideas, you guys!
• In Kakeru's sequel, he and the protagonist are splashed with an angel-made poison designed to harm demons. As the resident expert on angel weapons, Haruhito is brought in to assess the situation. It's quickly determined that Kakeru will be just fine, but as for the protagonist... Haruhito starts dithering, noting the significant differences between demons and humans, while Kakeru grows more and more agitated. Eventually, Haruhito cheerfully admits that since the poison was made for demons, it won't affect humans at all.
  Kakeru: Why didn't you tell us that first!?
  Haruhito: But you're so funny when you're desperate!
• In the "Black Valentine's Day" side story, Kakeru has some trouble wrapping his brain around the custom of giving chocolates, particularly once it gets into the distinction between obligatory chocolate and the heartfelt handmade chocolate given to the one you love.
  Kakeru: Wait, chocolates don't contain souls. This is confusing.
