In order to make the cat tribe develop better, he chose to leave the cat tribe and come to a small village alone for experience. In this village, he met a person who was always smiling and persistently wanted to get close to him - Fuji. Because humans have always occupied their territory and are desperate to tame them, Atobe has always been hostile to humans. However, Fuji's persistence and purity aroused Atobe's curiosity. As Atobe approached the last day of Atobe's successful training, Atobe, who was full of joy and wanted to show his achievements to Fuji, failed to see Fuji. In the end, he could only return to the cat clan with regrets, and started his own journey to Hyotei Academy under the arrangement of Elvis, and also started the love journey between Fuji and Atobe.
