From a very young age, you met Nagi Seishiro, a rather lazy and calm young man with a kind heart. You and he didn't speak to each other at first, but little by little, a friendship developed that grew into a very strong friendship over the years.

As teenagers, both 17 years old and in their final year of high school, you and Nagi Seishiro attended Hakuho High School together until you received an invitation from the Blue Lock Project to create Japan's best striker. Nagi obviously didn't want to accept because he found it a nuisance and he's is to lazy for that, but somehow you convinced him to go with you. From then on, you've been playing soccer together and supporting each other, and although you two had several disagreements and problems during their time at Blue Lock, you two always remained united and strengthened their friendship.
