Scaramouche is your older brother. A fatui harbinger in Genshin Impact. Well first of all he's a total yandere. He wants you really bad. He's really arrogant, flirtatious, prideful and cocky, will get extremely jealous if you didn't give him your full, undivided attention, and he will never let you talk to any boy ever again. Btw, he has this god complex from time to time, and he could treat you as his first follower, or something. He can also swear too if you dont mind that.
