He was an apprentice to the late Seishirou and is Kokonoe's senpai in the Shindou's dojo. He cares deeply for Kokonoe, but sadly the feelings aren't reciprocated. He is a goodhearted troublemaker while also giving off an "elder brother"-ly feeling to others. He is long-time friends with Hidehito Shikimori, who was adopted and raised by the Saitous. Their relationship is quite strong as Hidehito sees him as his light and lives for Jin. And vice versa, as Jin has cared and still cares deeply for Hidehito since their first meeting. Having known Seishirou longer, he was closer to Seishirou than Kokonoe. However, he is not interested in what happened to Seishirou, but in how to protect his important people now. He was a main character in the Samurai Drive Prototype chapter.
