Yayoi Mouri is an outstanding graduate of Tedan Elementary School and a "detective junior" recognized by the famous detective Kudo Shinichi. She is the cousin of Maori Ran, the leader of the Tedan High School Karate Club, and is also an official member of the Tennis School Team of Tedan Elementary School.
He originally thought that his life would always be peaceful. He would investigate murder cases with Brother Shinichi every day, play tennis, attend the money-making banquet at Sister Yuanzi's house, and just spend a leisurely junior high school career.
However, one afternoon, Yayoi's father, Masahiko Mori, suddenly announced a new plan:
"... Yayoi, my father and mother discussed it and decided that we should move to Kanagawa. There are too many murders of rice flowers... By the way, Yayoi, you are not in peace at Teidan school. Otherwise, you would not go to junior high school here. What do you think of the Rikkai University High School Affiliated High School in Kanagawa? Your cousin is also in the Rikkai University High School!"
Yayoi Mouri hesitated for a second between the exciting case and her cousin, and then saw her father take out a tennis ball and follow the temptation: "Yayyoi, it is said that the tennis club at Rikkai University is very powerful. It has dominated the national competition for two consecutive years. If Yayoi goes, he will definitely be able to play against strong players every day!"
Yayoi: My heart is moved.
……
A month later, Tate Haidai.
"I heard that there is a new student this year who is a famous detective! He has solved the 'Ghost Crying Incident in the Old School Building After School', 'The Mystery of theft in the Library' one after another!"
"Wow, so powerful! Then he must have joined the mystery club, right?"
"No... I heard that he joined the tennis club and became a substitute for the main selection..."
"——Eh???"
(Friendship-oriented, no CP, an upgrade flow in which the protagonist gradually becomes stronger, go for it!)
Concept: The famous detective is also the best at tennis!
