Kōken Yasaka

is a former member of the Fallen Angels.

Appearance
Yasaka is a tall, lean-built man with dark hair with dark eyes. His hair is neck-length and slicked back. He also has thin eyebrows, thick sideburns, and a developing beard growing around his face. However, sometime after his first day at Ishiyama High School, his sideburns have grown to the point where they curve inward towards his cheeks and he has shaved his facial stubble to grow a thin goatee instead.

He wears a dark, leather jacket left open with the sleeves rolled-up and his collar upturned. His jacket contains two breast pockets, one on either side of his chest. It contains numerous stud-like adornments on the exterior which is particularly notable on the collar and lapels of the jacket. Underneath, Yasaka wears one of his V-neck shirts which are either dark with a light-colored neckline or simply light-colored overall. Yasaka appears to wear dark gloves to compliment his thug-like outfit.

Yasaka wears dark sunglasses which are often adorned over his forehead, just above his hairline. He has two stud earrings on his right ear. He also has a distinctive, inverted diamond-shaped scar on his right cheek, which he apparently gained sometime after first attending Ishiyama.

Personality
It appears as though Yasaka is fond of smoking.

History
Yasaka originally attended Daten High School until he transferred over to Ishiyama High School.

Return to Ishiyama High School Arc
Yasaka arrives at Ishiyama High School on the first day of the new semester. He stands behind the school's entrance, smoking a cigarette, and telling himself about how every newcomer at the high school wants to reign at the top of the student hierarchy.

Several days later, Yasaka sits in an office-like room inside a building with two others. Outside, Himekawa waits to begin his fight with Tōjō. One of the people with Yasaka ask him whether he actually can trust someone with as shady of a history as Himekawa. While holding up his left hand, Yasaka states that he cannot but trails off as he prospers the idea of Himekawa taking down an opponent as powerful as Tōjō. He later smiles shortly after the event occurs.

Yasaka is then seen sitting at the head of a pool table alongside several of the other Fallen Angels, waiting for Himekawa to arrive, which he eventually does. Yasaka then calls for Takamiya to start talking and sits in while the first-year speaks, grunting noticeably from afar. Afterwards, he notices a commotion outside the classroom and watches, unfazed, as Oga appears. Yasaka takes no action whatsoever during Oga's brief moment with them and also says nothing when Himekawa concludes what they should do against him.

Quotes

 * (To himself): "There's only one seat at the top of Ishiyama... and all the up-and-coming powers want it."

Trivia

 * Although Yasaka is the most powerful member of the Fallen Angels after Takamiya, making him the first-year's strongest subordinate, he is often mistaken to be Takamiya himself, proven in many other delinquents' own depictions of the former head.
