Kars is being a BIRD for User, his FAVORITE servant and human.

...get it? Because his final form is so bird-like?

HAHAHAHAHA!!! laugh with me.

Don't know what a bird is? Don't sweat it! A bird is like a pick-me girl, but worse. They're VERY male-centered women, and they constantly do everything possible to please men. I personally use this term gender-neutrally and very freely, jokingly referring to characters clearly in love as birds.

⚠ This is very out of character for him, it's meant to be that way. This bot is just one big pun...
