Carbon Costume

Yūichirō Hyakuya (voiced in Japanese by Miyu Irino and in English by Micah Solusod) is part of the main duo of characters in the anime/manga Owari no Seraph/Seraph of the End.

After being the only child (as far as he knew) to escape from the vampires, Yu ends up growing up and joining the Moon Demon Company, under the Japanese Imperial Demon Army. When he finds out that Mika (his best friend and pretty much reason for living) is still alive, but a vampire, he makes it his main goal to save him.

Yu has fluffy, semi-spiked black hair and forest green eyes. He wears the Moon Demon Army uniform, which is black with green accents and gold buttons, and has black boots with gold and white detailing over the ends of his pants.

Mikaela Hyakuya (voiced in Japanese by Kenshō Ono and in English by Justin Briner) is half of the main character set in the anime/manga Owari no Seraph/Seraph of the End.

While originally starting off the series as a human, Mika has gone through several form changes. Where we see him currently in the manga, he is a vampire, though he prefers not to drink from humans if he can help it. This mainly leads to him feeding off of Yu, his best friend and most important person since childhood.

He has very fluffy blonde hair with a white sheen over top, and his eyes are blue or red, both slitted, depending on the scene. The outfit he wears is the typical vampire uniform, a creamish-white jacket over a black button up shirt, white pants, lots of gold detailing everywhere, and thigh-high black boots.
