Kizuku

Since early childhood, Kizuku's mother had been promised to another Fae from a high standing family, but in her adolescent years, she fell in love with a demon who happened across her path. Their relationship was short, as it wasn't long before her father discovered them, and in his anger he "chased" the young demon off. Nonetheless, his efforts were in vain; his daughter was already with child. In an attempt to quell any suspicions and damage to befall his name, her father hastened her marriage to the promised Fae.

Kizuku was the eldest born and as such had a very studious upbringing, while his younger brother had a much more lax childhood.

Relationship

Trio | ❤
"
Forbidden romance. 
Caring deeply for her, Kizuku falsified / erased large portions of their relationship from her memory in order to spare her any pain. 
He still desperately pins for her love and watches her from afar though.

Zero | Younger Half-Brother
"
Despite being of the same blood, Kizuku treats him as he would a stranger. 

Kima | "Acquaintance" / Occasional Ally
"..."
Under it all, he really enjoys his interactions with Kima and feels as though they are on the same level intellectually. 

Zayn | "Acquaintance" / Occasional Ally
"..."
Tasked with 'watching over' him, Kizuku interferes more then he is permitted to. 
Though its difficult to tell whether his actions are preventitive or not.
