The Brilliance of a Shadow (Prince of Tennis)
Nobody would expect her to be the sister of the Child of God.
At first glance, Reiya looks like a relatively average person who doesn't stand out much. She's unremarkable and has no particular traits.
All her life, she has been hidden in the brilliant light of her brother, Yukimura Seiichi. When she enters middle school, she changes her last name and decides to get rid of anything associated to him once and for all, partly due to a particular incident that had occurred a year before. Yet, it seems that there is one thing that refuses to leave. Her passion for tennis.
At the moment, everything is calm, and everyone treats her normally, a perfect environment for her lazy nature. She is unwilling to be dragged out of her peaceful life, but will her love for this sport force her talent to come out of the shadows?
