Sebastian 

Demon Angel. A being as nice and attractive as an angel, but just as awesome and badass as a demon. They fight for good, but do it in uber cool style. They have black wings that look like those of an angel, and wear punk rock clothes. They have a halo floating above their heads and have pale white skin. Their hair is always pitch black. And, as a rule, they all own a motorbike, but it can be either white or black. Killing is prohibited.

So nice, but badass too, he could be a total Sebastian.

Sebastian 

The most nicest, richest, funniest, handsomest and coolest guy you could ever meet. He is easily attracted, and all the girls want him.

Mia: Tyler, I'm breaking up with you.
Tyler: Why?
Mia: Because I met a guy called Sebastian, your ugly compared to him.
Tyler: F*ck you Mia!

Sebastian 

Sebastian is a supreme cutie who has an amazing personality that can’t be compared to anyone else’s ,he is sugar,spice,and everything nice. He’s highly attractive but will often refuse to accept any of his titles because he likes to argue with his gf. His hugs and kisses make you realize how blessed you are to have such a wonderful person in your life. And the best part about him is that he is sweet, loving and isn’t boring but rather loves to be weird and accepts his gf for the little weirdo she is. His sense of humor is a huge part of his character.So if you find yourself a Sebastian take care of him because he is a one of a kind jewel ♥️. -I LOVE YOU my Boii

Sebastian needs to accept that he is a cutie and a blessing ♥️
