As the Son of a God, I Just Want to Play Tennis

[After discussing it with my editor, this novel will go premium this Friday, December 19, 2025, starting with Chapter 24. There will be a 10,000-character update on launch day, followed by daily updates after that. (This is a correction from March. Since I need to prepare for the civil service exam, the CET-6, and my thesis, daily updates won't be possible. I'll only be able to update according to the rankings.)] [Chapter comments are open with no restrictions. Discussions are welcome.] [Since I'm revising the novel, some comments and chapter comments may no longer match the current content. I don't recommend reading Chapters 47-52 or 136-144. The former were revised once but are still poorly written, and the plot later veers off course. The latter have the same problem: the plot strays, and a perfectly good school festival performance somehow turns into a shonen battle anime?!] What does it feel like to be casually abandoned by your own blood relatives? Kirishima Masaki is the best person to answer. Fortunately, the great onmyoji hailed as the "White Fox Prince" a thousand years ago gave him a new home, and his childhood friend Byodoin, as bright as the sun, showed him the way. But as a genius who learned everything quickly, Kirishima Masaki had long been troubled by a deeper sense of emptiness. Reaching the top of any field was so easy that the summit itself had lost all meaning. That changed when his childhood friend Byodoin introduced him to tennis. The sport became different because of the people in it: there were companions who stood beside him, and challengers who set his heart racing. In the finals of the National Tournament, he met Rikkai's "Child of God," the opponent fate had chosen for him. To win, he broke through the taboos within his own body, and was swept away by a demonic sword into the Warring States period five hundred years in the past, where he uncovered his astonishing destiny as the son of a demon god. After regaining a healthy yokai body and gaining unfathomable power, he entered the U-17 training camp. Everyone respected the absolute strength of the number one, yet no one saw the truth hidden within the gentle new arrival. The World Cup stage is slowly being set. A battle that no longer needs to be concealed is about to begin. ※ This is an ensemble coming-of-age story, with a slightly pampered protagonist. The main plot is about competitive tennis and making peace with oneself, with a focus on the bonds between the protagonist, his childhood friend, his adoptive father, and his companions. ※ Kirishima Masaki's growth in strength: Early on, approximately equal to Yukimura; later, stronger than Byodoin. ※ From the time Byodoin joins the team until the protagonist graduates, Makino Fuji wins four consecutive national championships. Rikkai is the Kanto champion and finishes second and first nationally. (In the protagonist's first year of high school, Rikkai is disqualified after Seigaku reports a substitute player's identity. Makino Fuji finishes second that year.) ※ The protagonist defeats Yukimura at the National Tournament, but Yukimura's illness is discovered early and successfully treated (in his second year of middle school). ※ Includes side pairings such as TsukiSaa and KimiAtsu, but they don't take up much of the story. The ending separates Sesshomaru and Rin, while Inuyasha and Kagome live in the modern era. ※ Shuten Doji and Ibaraki Doji are based on Japanese mythology, with many original additions. The timeline has been changed. ※ Please don't scrutinize every detail too closely. I hope you enjoy reading. ※ I'll update this section whenever I think of or write anything else. My other ongoing novel is A Little Crow's Travel Diary. My name is Little Crow. They say I'm a replica blade of Higekiri, one of the Genji family's treasures. But now I'm a Saniwa in the Time Government of another world, and a lone soul lost among countless worlds. Before I became a sword, however, I was Minamoto no Asahi, a Heian-era girl destined to become the strongest miko, and the kindred spirit and fiancée of Minamoto no Yorimitsu. To suppress the evil god of legend, I, who died young, willingly became a blade and offered myself to Yamata no Orochi. From then on, the gods of Takamagahara called me "Yatagarasu," while the Minamoto clan called me "Little Crow." I've traveled through fragments of worlds, touched the traces of time, and drawn the attention of countless worlds. Salvation, miracles, obsessions... But all I want is to return home. #The child I raised seems to have turned out wrong. Wait, I didn't raise him. He's the counterpart of a child from my own world. Never mind, then.# #I just want to go home. Why does it feel like more and more people are falling for me?# #Mom, love me again! That was something my counterpart did, not me. Don't hit me!# ※ Characters may be out of character. ※ This is not a canon-compliant story. This is my take on Little Crow, with plenty of original settings. ※ I stick to the principle of one Honmaru per Saniwa. ※ Planned worlds include man-eating demons, the Holy Grail War, and more. Coming soon: A fanfic of the same type: Niou Masaharu, no pairing, Niou-kun from Germany. Rikkai has 16+3 players and the German team wins ten consecutive championships. Touken Ranbu otome: The Saniwa Is Still Avoiding Romantic Debts Today, about falling in love with swords and their former masters. Theme: True strength comes from understanding and protecting our bonds with the world, not from power we are born with.
