Nishino: the boy at the bottom of the school caste and also at the top of the underground, 西野～学内カースト最下位にして異能世界最強の少年～

Nishino Gokyou was a high school student who felt like he didn't quite fit in. Despite being very talented and skilled, he often kept to himself and spent most of his time working alone. However, during the culture festival in his second year, he realized the importance of friendship and having connections with others. This led him to decide that he wanted to make a change in his life and become more outgoing. He also decided that he wanted to find a girlfriend to enjoy high school with. To achieve this goal, Nishino worked hard every day and used all of his abilities to try and climb the school caste. However, it seemed like there wasn't much chance for him to succeed. Despite this setback, Nishino remained determined and continued to work towards his goals.
