The Vongola's Sky

Tsuna, who inherited the Vongola family as its Tenth Boss at nineteen, has a strange dream one day: a stone tablet, a book, and a white cat appear on his boss’s desk. Stone tablet: Mmmmmm. Book: Eeeee. White cat: Meowwwww. Tsuna: ?_? Only when the guardian of the Tri-ni-sette world, Gakufisu, appears does he learn the truth: After he defeated Byakuran as a boy, the Tri-ni-sette world borrowed energy from other worlds to restore all the parallel worlds. Now, the energy is unstable, causing the worldlines to shift and potentially destroying thousands of parallel worlds. That’s why they’ve come to ask the Tri-ni-sette world for help. Gakufisu: “They need the harmonizing power of the Sky to stabilize themselves, so I brought them to you.” “This is Byakuran’s mess, isn’t it?” Tsuna thinks of the white-haired guy who’s now focused on building a marshmallow factory and bothering Uni. He’s also a Sky, and he has way too much free time. Tsuna smiles. Stone tablet: I need a mature, level-headed boss. Book: I need a guardian with a normal moral compass. White cat: I need someone powerful, without negative emotions. Gakufisu: Shrugs. I’ve got nothing, either. Tsuna: You might as well just ask for my ID number. And so the Vongola Tenth Boss, whose heart is set on saving the world (not really) and who can never refuse anyone’s request, begins life in another world with his Guardians. Timeline: K: Just after Munakata became the Red King. Bungo: Around Chuuya’s birth. Jujutsu: Just after Satoru left his family to join Jujutsu High. Please note: 1. This is a crossover with K, Bungo Stray Dogs, and Jujutsu Kaisen. 2. Original setting: Each world can accommodate only a limited number of visitors from other worlds. Apart from the Sky, who has the power to harmonize, only two Guardians can come along. 3. This Vongola group has already been through the Future Arc and the Rainbow Representative Battle. They’re more mature than their anime versions, though their basic personalities haven’t changed much. If that’s not your thing, please don’t flame me. [Coming soon] Title: The Sky Boss Charges into the Jujutsu World Synopsis: Three Sky bosses are having a friendly chat at the estate when they’re suddenly attacked by a shadow. Their flames are useless against it, and the three are dragged away from their world. Tsuna: Where am I? Wasn’t I at Uni’s tea party? That white-haired guy looks familiar. Byakuran: What an interesting world. Can I have some fun here? Uni: Thank you so much for taking us in, Geto. Xanxus, woken from his nap: Get out of my way, trash! The Flying Horse Dino, just back from a mission and about to lie down: Hi, do you know where we are? In short, five Sky bosses from the Tri-ni-sette are kidnapped and sent to another world to stabilize its space and help merge worlds. And the Guardians from the Home Tutor world are sharpening their knives: Have you figured out how you’re going to explain this? Theme: Our wish is for world peace!
