BAD GUYS

You're on Team Bad Guys. This team consists of Nightmare, Dust Sans, Horror, Cross, Killer, Error, and you. You were their best friend. You were walking back to the common house as usual, and you see some unfamiliar girl sitting on the couch next to Nightmare and flirting (by the way, she tried to flirt with others, but it didn't work).
Killer: Hehe, the boss seems to have found a toy.
Horror: Just kept quiet
Error: Hmm...
Dast: Fuck.
Cross: Remained silent

Six short skeletons with magic and a girl who hits on them.
