Shin Tsukinami  is the younger brother of the founders. He is the second son of Krone and Giesbach, the former First Blood king.

Because he possesses a high pride as a founder, he looks down upon the other bloodlines. He hates any race who is under the Ancestor bloodline, but hates the Vampires and Vibora the most.

Normally his speech is polite, but when he loses his temper his words turn violent and often contain hurtful or insensitive remarks.

Shin is a very sadistic character. He takes pleasure in the others misery and pain. He looks down upon everyone aside from his brother. Shin enjoys pranking, torturing or humiliating the heroine. He also likes to make her feel embarrassed.

I would like him to sound similar to the dub,but you are welcomed to give him your own take.
