Satoshi Yamanaka

Satoshi Yamanaka 「山中聡, Yamanaka Satoshi」 is a student at Second Shibuya High.

Appearance
Yamanaka has short, thick eyebrows with narrow eyes and pupils. He has a short, rough hair cut that is spiked in the front. He wears the standard student uniform with his collar, and he keeps the first two buttons and the last button of his jacket undone. Sometimes, he unbuttons the entire jacket. He does not keep his shirt tucked it, and he often swaggers around with his hands in his pockets.

Personality
Yamanaka takes advantage of people for selfish purposes and bullies others. He has no problems lying to or manipulating people, even offering them false promises like membership to the Moon Demon Company. He's a coward who tries to act intimidating. When a real danger presents itself, his bravado dissipates, and he becomes an immobile, trembling mess.

Given all that, he still cares about his friends and is willing to be humble enough to beg for help when they are in danger.

History
Yamanaka is a student at Second Shibuya High. He tells the other students that he is joining the famous vampire extermination unit called the Moon Demon Company in order to make them fear him. When Yoichi Saotome fails the application test to enter the Japanese Imperial Demon Army, he tries to become closer to Yamanaka in order to be allowed a retest.

Story
Yamanaka appears in chapter 2 after knocking Yoichi Saotome to the ground. He kicks Yoichi around to make him buy drinks for him and his buds until Yūichirō Hyakuya interferes. He and his friends ask Yu what he thinks he is doing. When Shinoa Hīragi mentions that Yu's suspension will be extended if he gets caught harming a civilian, Yamanaka manages to punch you. In the end, Yu goes with Yoichi to get their drinks.

A weakened vampire escapes from a lab and enters their classroom during this time. When Yu fights her, he orders Yamanaka to get an injured student out oft he room, but Yamanaka confesses to lying about being in the army and is too scared to move at all. Fortunately, Yu and Yoichi manage to fight the vampire. She takes Yu through a window outside, where she is exterminated by Lieutenant Colonel Guren Ichinose.

In the following chapter, Yamanaka and one of his friends chase down Yoichi, apologizing for picking on him after hearing he got into the Moon Demon Company. He asks Yu and Yoichi to help his friend Yuji, who entered the forbidden chamber at the school, which is one of the army's class-1 restricted zones, and has yet to return. Shinoa tells them that Yuji was probably arrested and may even be executed. She says they cannot save him.
