Why does Tohru always try to get Kobayashi to eat pieces of her tail? In Kobayashi-san Chi no Maid Dragon, Tohru always tries to get Kobayashi to eat pieces of her tail. Why?  This started in episode 1 and has carried through to the current episode, with a mention/attempt almost every episode.

Is this a sign of affection for dragons?
While it hasn't been explicitly stated in the show, I think the biggest factor is that it's an extremely intimate thing to do. It might be a bit disgusting when put this way, but a lot of intimate acts amongst humans involve the mingling or exchanging of bodily fluids; and that extends to the deal with vampires drinking blood - it's a precious bodily fluid, and there is something quite intense about giving it to someone. So for Tohru, who can apparently regrow her tail pretty quickly, having Kobayashi eat the meat is having her master take a part of her and ingest it, which in her eyes is an incredibly special form of bonding.
