Yuusuke Ijichi

A classmate and fellow otaku friend of Ryuto Kashima, he initially appeared as a somewhat overweight math enthusiast on the fringes of social circles. Following a failed confession to Akari Yatanokita, he demonstrated extraordinary willpower by secluding himself at home to transform his physique, ultimately returning to school with a strikingly handsome appearance that caused a sensation among his peers. He stands out as one of the most dramatically transformed supporting characters in the series.
