[The Prince of Tennis X Katekyo Hitman Reborn] Sister, Come Home with Me

※※※※※※※※※※※※※※※※※※ This is the story of a younger brother who follows his big sister to another world with their friends, only to discover that she has a boyfriend and do everything he can to stop them! Tsuna: Sis, wake up! We're not even from the same world as him. You two can never work out! Even if the person you have a crush on doesn't like you, we can settle for Hibari-senpai instead! Kotone: Kyoya Hibari? Even if he has the face I like, I could never truly fall for him. Tsuna: Then please keep liking Hibari-senpai's face, forget this Atobe guy, and come home with me. Hibari: Herbivore, what nonsense are you babbling about? Tsuna: H-H-Hibari-senpai?! I'm sorry! Sis, pick Yamamoto instead, or Gokudera-kun would be fine too. Kotone: Tsuna, selling out your friends in front of them like that will make them cry. But now that you mention it, I think I might actually like him a little. Tsuna: Nooo! Atobe: Sawada Kotone! How much longer are you all going to ignore me, the great Atobe?! Also known as: #How to Fall in Love When We're from Different Worlds# #The Days I Tried to Stop My Sister from Dating a Rich Guy# ☆ Reader's Note ☆ ○ The story's settings roughly go Prince of Tennis - Katekyo Hitman Reborn! - Prince of Tennis. It doesn't involve the main plot. ○ Everything serves the story, so there will be plenty of things that don't make sense. If you're the type to nitpick, please don't read. ○ The current direction may well turn into a comedy. ○ My goal is to write an adorable Atobe! Note: The characters may be OOC. ○ I came up with this idea nine years ago, and recently drafted an outline, so I'm bringing it back to life. My writing is as bad as ever, so please click the X if it bothers you. ○ Finally, I hope you enjoy reading.
