[Crossover] In the End, I Saved Kanagawa

My school's tennis club has a banner that says: "Victory after victory is destiny." I like victory after victory. I don't like destiny. I'm Yagami Mikoto, though the Chinese characters on all my documents spell my name as Yagami Mikoto. I'm an ordinary Colorless King, living in Kanagawa with my ordinary twin brother, Yagami Light. I met Sister Kobayashi first, but the monks from Byakuenin tricked me into joining the Shinkakushu. Anyway, after living in Kanagawa for six years, I ended up saving Kanagawa along the way, all while being an ordinary high school girl. Reader's Guide: 1. The heroine's first-person perspective, no CP. 2. The heroine is a crazy, overpowered character. 3. Mainly Prince of Tennis, with K as a backdrop. DN is basically nonexistent. 4. Original characters appear, lots of original settings, and the timeline has been thoroughly scrambled. 5. Some characters are out of character, especially Yagami Light. 6. The author updates whenever possible. That's all. If anything bothers you, please click the X and escape right away. Thanks for your cooperation.
