Nogami Kirito

He currently lives in Saitama with his mother and older brother, Tokia, at their family home. Unfortunately, his father passed away in an accident when he was still a baby, so he has no memories of him. During his school years, he worked part-time jobs along with his brother to support their livelihood. Like his brother, he initially had no plans to go to university and wanted to start working right after high school. However, his mother and Tokia convinced him that he should pursue a college education. Eventually, he decided to enroll in university. Even during his time at university, he continued to look for part-time jobs with higher hourly wages to support his tuition fees. (Though he had low attendance and barely managed to graduate with passing grades.)
