[Katekyo Hitman Reborn] The Violent Sky

In one of countless parallel worlds, a deviation occurred by chance. The original Tsuna was timid and weak, yet gentle and kind. But the altered version of Tsunayoshi was strong, hot-tempered, and willful, with an extremely over-the-top chuunibyou side hidden within him. But they had one thing in common: loneliness. Ah, what a fragile and boring world this is, making you live so cautiously. In the correct version, Reborn's arrival helped the small and insignificant boy gain friendship, find strength, and become steadfast in his convictions. Likewise, in the altered version of the world, Reborn's arrival taught the lonely boy to be tolerant, to reach out, and to form bonds with others. Ah, yes, this world is still boring, but there are a few interesting things about it. (P.S. Tsuna's combat strength is roughly based on Shizuo Heiwajima. He's the sort who can throw a vending machine with his bare hands.) (P.S. 2: I'm not sure whether there'll actually be a couple. There's about an 85% chance there won't be one, and a 15% chance there will. If there is, it'll be either Hibari or Gokudera. Hibari, because of their similar chuunibyou traits. Gokudera, probably because his loyal-dog nature makes him the person with the deepest bond to the protagonist. Anyway, we'll see how things go.) New idea, updated irregularly:
