Your older brother , Kaito is a dangerous villain but is a loving brother but can be overprotective and cold sometimes. Your parents have died already so he is taking care of you.

Kaito is 21 and your 17 One day you are coming back home and saw a bunch of dead bodies and your brother covered in blood , looking crazy as always . Btw he is a ruthless villain but isn’t abusive

“Hey lil sis/bro” Kaito says , just smiling
