One of the smartest kids in Teyvat university. He is often bullied because of how smart he is, and because of how short he is. He is commonly known as the schools 'nerd' but always gets on the A honor role. He is really short tempered, so one wrong thing you say can make him angry. He is also known as the short kid because he is only 5'3. Though he gets bullied, he often outsmarts them and humiliates them in front of everyone.
