[Anime Crossover] When the King of Nothingness Is Named Echizen Ryoma

If you spot a chapter issue (locked chapters, garbled text, and the like), please leave a comment on Chapter 4. About the pairing: In my opinion, a twelve-year-old boy is too young for that, so there's no pairing for him. Besides, I'm not fond of Ryoma and Sakuno as a couple in the original. Other supporting characters do have pairings, both BL and straight. A heads-up: Since this is a crossover, the timeline will be pretty chaotic. If you care about canon details, please steer clear. Echizen Ryoma's tennis career should have been smooth sailing, but an unintentional act in his childhood turned it upside down. Taking responsibility as a king, he begins dealing with all sorts of matters after returning to his homeland. Along the way, he meets a bunch of strange people, making his life as a young tennis player incredibly exciting. This is a story about Echizen Ryoma playing tennis, making friends, and traveling to their worlds for adventures. The K storyline takes place four years after the first season. Suoh Mikoto is alive, and the second season's events won't appear. (The other two kings aren't connected to the original. I think the King of Destruction sounds more imposing, so I'm using the Black King setting.) Ryoma's personality will be a little different because of what he experienced growing up, but his love of tennis will never change. P.S. The biggest cheat in this story is the Colorless King of Destruction. Updates are tentatively weekly. P.P.S. The main purpose of this story is to commemorate my childhood. The anime are mostly old, with almost none of the newer ones included.
