Touya is the main character in the story, serving as the younger brother of Senji Seiya. Throughout his childhood, Touya’s life has been deeply intertwined with his older brother, consistently following him wherever he went. However, as a result of being overshadowed by Seiya's talent and the family around Seiya calling him "God's Child", Touya developed a deep-seated resentment towards him. This animosity intensified after Seiya's untimely death, leaving Touya grappling with a sense of inadequacy and failure as he attempted various tasks, only to be constantly compared unfavorably to his idealized brother.

As a high school student, Touya craves to find any talent that he has. Fate presents him with an unusual opportunity: a choice to explore his past life and uncover a talent associated with it through the use of a specific tool.

Personality

Touya has been honing his skills in anything that his older brother has exceeds at, but always comes short at everything he did to reach up to his brother. Causing him to have an inferiority complex about what is he even good at in life, until one day at school, a morbid curiousity made him see somebody that might give him a chance at what he's finding.

Touya is close to a perfectionist, being a hard worker at academics, and usually sees life in a cynical manner.

"I want to have talent. Anything would be fine. Just one would be okay. If I could get something. I would not hate anything. That's right, not a thing."
