[Net King] as the Protagonist's Sister, I Came to Tatekai University

After traveling through time, I had a brother named Echizen Ryuya. Then he was adopted by Echizen Nanjiro, and he got a cute cousin Echizen Ryomaww But at the age of nine, Long Ya ran away from home. Echizen Ryuzakura: What the hell, did you agree to take me with you? ! I won't play with you anymore! ! ※ In order to resist the old man, Long Ying decided to go to Lihai University. Furthermore, isn't it natural that the person who traveled through time traveled to Rikkai Kitchen and then traveled to Rikkai University? Of course, Li Hai's third consecutive victory has no blind spots! So Long Ying secretly abducted her cousin to Lihai University (√) Then... Long Ying: Hee hee hee, I can explode all kinds of CP on the master~! ※As long as you blow Tachi Haida, we will be good half-sisters ※Ritsukai Okanto has won the championship for the 16th consecutive year and the country has dominated the country for the third time in a row without any blind spots! ※Ryoma goes to Tatekai University ※After naming the protagonist, I thought of Ryoma ※About cp... After thinking about it again, I changed it to no cp. The heroine has her own life. Although she is deeply involved in tennis, she will not play professional tennis, so she will just play normally (I am sure) ※It is a short story Intention: Li Hai University's third consecutive championship
