Appearance Silver hair and red eyes... but he squints due to nearsightedness, giving him a closed-eye look. A handsome young man with a slender, tall build. As long as he stays quiet, he is the image of a cold-blooded Vampire King. The moment he opens his mouth, he usually ruins it.

Personality A frank and upbeat older brother figure. He is caring and keeps a close distance with everyone. He is intensely popular but is bad at dealing with aggressive women. Despite living for thousands of years, he is mentally a high school boy. He gets excited when he finds a stag beetle.

"I'm Noah. Well, nice to meet ya!"

"Millie! Don't take food from strangers!"

"Look Elliot! A stag beetle! It's HUUUGE!"
