Karasuma Ouji is Tenma's love interest, often portrayed as an expressionless eccentric. He has peculiar habits, such as dressing up as a kappa on rainy days, playing on the Japanese word for raincoat. He has a fondness for curry. Though he never speaks about it, he seems adept at dodging flying objects, including Harima's Hurricane Kick and Tenma's arrow letters. Secretly, Karasuma is a renowned mangaka, publishing his work under the pen name Nijou Jou. At school, he plays in a band, handling the electric guitar. He also played soccer and recently won a cup with the national soccer team in the anime.
Despite not showing any feelings towards Tenma (or anything else), behind his stoic demeanor, he occasionally reveals genuine concern for her. Unfortunately, he suffers from a condition that gradually erases his memories after his trip to America. To avoid hurting Tenma, he conceals his true feelings for her.
