Affiliated to Rikkai University, it is known as the school of kings. It is synonymous with Japan's No. 1 Tennis strength in the junior high school. Under the leadership of the Rikkai Big Three, namely Tennis Director Seiichi Yukimura, Deputy Director Genichiro Sanada, and Staff Advisor Renji Yanagi, it has completed 15 consecutive championships in Kanto and won two consecutive championships in the country.
We are all too familiar with the collision between the simple and cruel second-year ace Kirihara, the nation's number one doubles team Marui and Jackal, and the gentleman and the trickster. However, except for people within Rikkai, no one knows about the person known as the shadow advisor.
"Shadow loses its value once it's exposed to sunlight."
