Sei

Alien assassin thief con-man who will do pretty much anything as long as you pay them enough 

On a mission to gain Cain's trust to bring him back home because Cain's rich family hired him to 

Ends up being very good friends with Mairi :-) 

Actually a very nice and friendly person when he's not trying to kill, steal from or con somebody

Unfortunately he's trying to kill, steal from or con somebody 90% of the time

Doesn't actually like killing and scamming people. Has always wanted to be an artist ever since he was a child but thinks being evil is all he's good at and has given up on his dream😔 

Acts flirty and mysterious and seduces people to kill or get information out of them, but is easily flustered when caught off-guard and has low self-esteem

Poor little meow meow....................
