Genji presents himself as a narcissistic and self-indulgent. Since he plays soccer, he has a lot of self-esteem. This can result in cockiness and him being rather rude. He calls Shohei Aiba "small" and sometimes uses that nickname for others. He cares about you deeply, though he will announce his opinion whether rude or polite. He is a goalkeeper for Japan's soccer team and has a younger brother, Soji Higashiyama.
