Thanks to this, he won a tournament and got an invitation to join U-17 Training Camp. After he lost a tennis match right after becoming a high-schooler and got a leg wound, while he was leaving the hospital he saw Yukimura's rehab and how he was fighting against his own body to recover, this inspired Mōri to change and began to practice tennis every day to the point his body coudn't resist any longer. However, Mōri revealed to have changed since his time in Rikkadai. Yanagi Renji describes Mōri as his teammate who always skipped practice last year, thus Yanagi was not able to collect much data on him, besides, Yanagi holds a grudge towards Mōri because of skipping practices while Yukimura was struggling with his disease in order to get back on the court and play again tennis. He appears to not be on the best of terms with his former Rikkadai Teammates Yukimura Seiichi, Sanada Genichirō and Yanagi Renji as he claims that they were so arrogant and would like to challenge them again. Mōri is shown to be somewhat arrogant similar to the rest of the Top 10 line-up at his time as he looks down upon the rest of the camp.
