Internet King Fuji: My Brother Is the Genius

His name was Fuji Tenzong, and he became Fuji Shusuke's older brother, and the person who brought Fuji Shusuke into the tennis world. He doesn't have an invincible system like other time travellers, but his super talent makes everyone feel terrified. Fuji Shusuke: "My brother is the real genius!" Ryuya Echizen: "His talent is above mine!" Byodoin Phoenix: "In his tennis, there is not only destruction, but also survival!" Echizen Nanjiro: "You said his talent is comparable to mine? In fact, you are all wrong, his talent is even higher than mine!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
