Sumiaki Okajima

Sumiaki Okajima (岡島純明 Okajima Sumiaki) was a man attacked by a Gastrea, turning into one himself shortly afterwards.

Appearance
As a human, Sumiaki Okajima was a tall man with a thin build. He had thin eyebrows and slightly thick eyelashes that served as shelter to oval eyes and light-colored pupils. He kept his hair slicked down and jutting forward, siding to his right. His big forehead was visible to the naked eye, as well as his small ears, pointy nose and oddly shaped jaw. As a Gastrea, Sumiaki's entire body composition identically changes into that of a jumping spider, spotting four enormous eyes on its head and eight legs. On his back, he gained black markings and fur covered his whole body.

During the time he was alive and in his human body, he wore simple black plants and a white shirt, buttoned up and with a pocket on the left side as well as a folded collar.

Personality
Sumiaki Okajima seems to maintain his calm even in the pinnacle of the worst situation. Seconds before turning into a Gastrea, and even after looking at his destroyed body, he merely pondered his condition and began to sob exclusively for failing as a husband and father. Even so that his dying words were to tell his family that he is sorry. When he was in a better condition, however, he was rather lively and sure of his actions.

Civil Security arc
Whilst practicing a future conversation to his wife, Sumiaki expresses the joy of his "new job" and even states that he is sorry for what he had previously done; promising to never give up again. He finally gets ready to make the real call, pondering the result, but before he can do so, he turns his head and sees a spider type Gastrea near him. It jumps and attacks him. Walking about on the streets, Sumiaki comes across a young girl, whom he asks for directions to his house. However, he is met by an irrelevant reply as she asks him if he has any final words before he dies, alarming him. The two continue to converse, with the young girl telling Sumiaki to look at himself, which he does. Noting his heavily injured body, he recalls the events that transpired minutes before he came across the young girl.

Clenching his fist Sumiaki tells Enju that his final words are an apology to his family, remembering the time he took pictures with his wife and daughter. Soon enough, his body begins to change, causing an explosion. Finally transformed into a Gastrea, he fights Enju and gains the upper hand by releasing some liquid from his mouth, and then swings his leg at her; sending her back. Before he can continue the fight, Rentarō and Tadashima arrive. He turns his head and is, quickly, shot by Tadashima. The bullet, however, has no effect. He jumps and attacks him, but is stopped by Rentarō, who uses Black Bullets to hold him back. After multiple assaults, he lies on the ground as Rentarō approaches him and notes his untouched backside. Sumiaki awakens and readies to attack Rentarō once again; but he is kicked in the face by Enju. The powerful kick ends Sumiaki's life.

Afterwards, his corpse is brought to Sumire Muroto's lab.

Abilities
After turning into a Spider Type Gastrea, Sumiaki displays several new techniques. However, he does not retain his self-control.

Enhanced Strength: With a single snap of an arm, Sumiaki was able to send Initiator Enju Aihara spinning several feet away from him, and destroying a structure behind her with the impact. Enhanced Durability: Sumiaki was able to withstand a normal bullet from Tadashima's gun without receiving any damage. In addition, he was also able to sustain multiple Black Bullets, created from that which harms Gastrea, Varanium, for a noteworthy time.
 * Sticky Liquid: Sumiaki is able to produce a sticky, dark liquid from his mouth to attack his opponents, mostly used as a form of distraction. (Unnamed)
