Surviving at Rikkai Through Tennis While Cosplaying Oda Sakunosuke

[Currently updating: “Can a Succubus Really Not Play Tennis?” Reading guide and content warnings at the bottom.] Hey, boy cosplaying as Oda Sakunosuke, can you see the countdown to your death right in front of you? In this tennis world, if you want to survive, you have to work hard at tennis. After three days of playing tennis: Ha, it's just tennis. I'm the U12 national singles champion! After three weeks of playing tennis: I-it's just tennis, isn't it? If I practice more, I'll definitely learn some techniques! After three months of playing tennis: No, System! You call this tennis??? What kind of tennis has sparks and lightning flying everywhere?! Oda Sakunosuke, a new member of Rikkai University's tennis club, shows off his extreme work ethic on his very first day. [Training sheet: Swing your racket 500 times] Oda Sakunosuke: 500? No, it has to be 1,000! [Training sheet: Run 50 laps] Oda Sakunosuke: At least 100! Kirishima, refusing to lose and working just as hard, lies battered on the ground: How much do you love tennis, anyway?! Oda Sakunosuke replies: I love it as much as my life. System: Congratulations, daily tasks completed ×2. Life points +1. Oda Sakunosuke: Great. I've lived another day. When his opponent sees him on the court: Ha, a new face. You're going down. Oda Sakunosuke, expressionless as he takes the court and beats his opponent without conceding a single point: Not unless I die. System: Congratulations on your first victory. Achievement unlocked: Making Your Debut. Life points +1. Reader advisory: 1. A cosplayer transmigrates into the story. This is not the original Oda from Bungo Stray Dogs, and his personality is different. 2. The story mainly focuses on The Prince of Tennis. Characters from Bungo Stray Dogs, Detective Conan, and other series may appear or pass through, but won't get involved in their series' plots. The main story is about playing tennis and staying alive. 3. Three thousand words updated daily at 9 p.m. If an update is missed, there will be an announcement. 4. No canon research. The story is full of original headcanons. OOC warnings, repeated for emphasis! Theme: Cherish life.
