Wrath

Wrath, formerly known as Sasajima Kyouya (笹島京也), is one of the student reincarnations. After reincarnation, he found himself reborn as a goblin in a goblin village. He has the special Weapon Creation skill and is currently the commander of the Demon Lord's Eight Demon Army.

Appearance
Pre-reincarnation Kyouya was described to have a shorter than average height.

As an Oni, Wrath has red eyes and multi-layered hair colors of silver and dark green. He looks similar to that of a human, however, he has a pair of horns sticking out of his forehead and fang-like teeth. He is also taller than an average human.

Wrath wears a Japanese-military style outfit made by Shiraori.

Oni Race
Oni are a unique humanoid monster species, evolved from an Ogre General. Evolving into an Oni raises the individual's level of Taboo, while decreasing their size to that of a standard human. Oni are solitary individuals, unlike ogres, and do not form communities or raiding parties with other ogres.

Personality
On Earth, Kyouya was a self-righteous, kind high school boy who could not stand bullies, often standing up to them for his own view of what is "right," even if it resulted in violence. He was nicknamed "imp" by his peers in junior-high due to his constant use of violence and small stature. In high-school he was able to endure the minor bullying and become friends with Shunsuke and Kanata, and often played games with them together. After being reincarnated as a goblin, he was getting comfortable with his new life when disaster struck and he went through many hardships, to the point that his personality and worldview completely changed.

During his enslavement under Buirims, Kyouya went through inhumane treatment and was forced to constantly make weapons using his unique skill, all while seething in fury towards his captors. He eventually reaches a threshold of rage, resulting in him changing his name to Wrath, the name of the ruler skill that he gained as a result of holding onto his rage for years on end. It takes a long time for him to regain his composure with the help of Shiraori, Ariel, and Sophia.

During the effects of the Wrath skill he will turn into a furious rampaging monster, abandoning common sense and the ability to control his actions. He describes it as becoming a bystander in his own body. As a benefit, though, the Ruler Skill Wrath raises the user's stats and abilities to the absolute highest values allowed by the System, surpassing even Ariel. He tries as much as possible to refrain from using this skill, as he is unable to regain control without intervention from outside.

When Wrath is under control, he usually has a calm and composed attitude; he always keeps an open mind during conversation and remains empathetic to others' situations, even still, he does not waver in his own world view. He also commands a powerful presence, forcing others to acknowledge him with little effort. Shun describes him as an unstoppable blade when they are first reunited. Unlike when he was Kyouya, he knows that sacrifices are unavoidable to achieve his goals.
