Kou Kouzuki

A not-so-average guy who has become the object of desire for many girls and at least 1 boy. He tries his best to survive.

Background
The heir to a massive vampire fortune. A handsome, muscled, and intelligent young man in his prime. A cobra-backed lover with expertly sculpted dark hair, a boyish grin, flawless complexion, and oh-so-kissable lips. You don't know whether to get lost in his mysterious blue eyes, or savor the sight of his tight six pack.

AMOG Genetics
Slayer genetics allow him to look in his 20s while still in high school. He also has a special gland that constantly emits female-attracting pheromones.

Magical Abilities
Kou has inherited a unique set of abilities from his parents, though he shares few with his sister. Some of his abilities have never been used outside of Inversion Impulse.

Reality Marble: The World (固有結界・世界, Koyū Kekkai: Sekai) - The ability to duplicate the world around oneself and "stop" (decrease to near 0) the flow of time for a number of seconds. Some beings with similar abilities or significant Mystery may still be able to move with varying degrees of success.

Climax (絶頂, Zecchou) - He is able to induce mind-melting sensations of pleasure through touch. Besides Kou, only his mother possesses this ability in his family.

Mystic Eyes (魔眼, Magan) - He can theoretically incur states such as paralysis or hypnosis in others just by looking at them. However, his powers are immature during the story.

Physical Abilities
Dead Apostle Constitution (死徒体質, Shito Taishitsu) - Due to his father's status as a Dead Apostle Ancestor and her mother's superior quality as a Dead Apostle, Kou also enjoys superior genetics. There is not a living mortal who can match him normally, let alone under Inversion Impulse.

If they have a food source (i.e. blood) Dead Apostles are able to heal their wounds by reverting the time of their body.

Talents
He can learn mostly anything after seeing it done just once. This is not a feat of demonic blood nor magecraft, but a results of genetics, i.e. IQ.

He has world class talent in playing the piano and most sports in existence.

He has received advanced black belts in dozens of martial arts, including ones kept in secret by mountain tribes.
