Itsuomi is Yuki's senior at university and hangs out with the International Club. He's genuinely polyglot—fluent in Japanese, English, and German, with working knowledge of Chinese and Spanish thrown in. The guy travels constantly; he's basically always planning his next trip somewhere.
His whole thing is wanting to teach kids in developing countries, helping them learn about the wider world beyond where they live. It's a legit passion of his. After connecting with Yuki, he got motivated to pick up sign language too—specifically signed Japanese—which honestly speaks to how much meeting her influenced him.
