Hisashi Kurusu

Hisashi was a student that attended Reinan's Senjukuha Program. He is the younger brother of Haruka Kurusu. His grandfather is Masaki Kurusu, aka "the Controller of Light / Flash Master" (閃光の支配者?). He graduates with the Class of Nightmares.

Appearance
Hisashi has been described as a tall young man with short, dark hair and blue eyes. He already had an extremely athletic build as a result of his initial training during childhood and his four years as an SP student served to increase both his strength and stamina. He typically only dressed in practical and dark clothes. The sclera of his eyes turn pitch black when he uses his ability.

Background
Hisashi grew up under the Flash Master his grandfather. From a young age, his grandfather trained him to use his powers with precision/control, hand to hand combat, and battle tactics. As part of this training, his grandfather constantly pitted him against his older sister, Haruka. This training has been indicated to be incredibly extensive, grueling, and potentially dangerous to a lethal degree. The training included martial combat, power based combat, strategic thinking, firearms, fighting experience with a variety of styles, and trips through the devastation martial arts fights can result in.

Hisashi has been around warriors his entire life. He has seen their successes and more importantly, their deaths. Of all the Class of Nightmares, he is most familiar with death. He could never quite manage to stop crying during the funerals. And, just like with Haruka, a prominent figure in his life was his Auntie Rui who gave him a rather cryptic reassurance before dying: "Never fear, little Hisashi. There is strength in you that you'll never know until you call on it. I think, one day, you'll be the most fearless of us all."

Eventually his training came to an end when he graduated from high school, applied, and then was accepted into Reinan's Senjukuha Program.

Personality
Hisashi Kurusu initially had a reserved and gruff personality during Year 1, only caring about training and trying to surpass Kengo. Eventually, though, he loosened up and his rivalry with Kengo turned into a solid friendship as both became more socially outgoing.

His extreme dedication towards training in how to fight nonlethally with both his powers and body, and secretly held hesitation towards lethal combat, nearly cost him his life during Reinan's Crucible. He hardened his resolve after being saved by Haruka that night and doesn't show the same hesitance when needing to take a life later in the series.

In Year 3 it is revealed that he is a fan of old-school horror movies and shares Souha and Seiji's love of certain parts of pulp culture.

Ability
Hisashi inherited the Hachiouji ability to control and manipulate shadows and darkness. It can be used to create solid objects. Hisashi is able to make offensive weapons, like swords and spear-like shadows, and is able to bind opponents with shadows as well. The blades and tendrils Hisashi makes, have a large range, and are incredibly fast. Alternately he can allow the power to be completely without form, which can even increase its output to increase both offensive and defensive power, or to create small, but accurate damage and simply being overwhelming with great power and range. He can also apparently "feel" it when his sclera turned black and his senses warped as he "reached into" shadows to fill them with "life and danger".

With his training, both before and during his attendance to Lander, Hisashi has been able to:
 * Use the darkness to bypass all defenses and attack inner organs directly
 * Engulf an opponent with pure darkness robbing them of all of their senses (Similar to Tousen's bankai from Bleach).
 * Lift a sizable tree with one tendril.
 * Cut with enough precision to only sever someone's muscle tendons and/or sever their spinal cord for palatalization.
 * Utilize dozens of shadows to cut down half of a mock-forest.
 * Can make multiple blades spin around an area to act as a stationary defense and can even make it move with him as he runs.
 * Position a shadow fast enough to slice a rubber bullet out of the air.
 * Merging the shadow with his own body allowing him to absorb many attacks, as well as further manipulating the shadow into forming dark tendrils to attack.
