Katekyo Hitman Reborn

Basically, it's going to be a parody. Except for a few changes. Like the strongest Famiglia is going to be Rinnegato followed Vongola, Shimon and Diavolo are equal in strength and all three are part of the Trinisette (think of the Trinisette as a physical item). The Famiglias of the Trinisette are the Rinnegato (the keepers), Vongola, Shimon and Diavolo (the three sets of ring bearers) and the Protectors (they protect the balance of the world).

Vongola is the Sky (Guardians are Sky, Storm, Sun, Rain, Mist, Cloud, Blizzard, Tornado, Lightning and Rainbow Sky), Shimon is Earth (Earth, Ocean, Forest, Desert, Swamp, Metal, Volcano, Glacier, Mountain and Rainbow Earth) and Diavolo is Space (Space, Planet, Star, Moon, Nova, Aurora, Asteroid, Meteor, Comet and Rainbow Space). Rinnegato would have thirteen core members (Rainbow, Rainbow Sky, Rainbow Earth, Rainbow Space and the nine remaining members would have three Flames each: a Sky Flame and the corresponding Space and Earth Flame). The Rainbow Flames are exclusive to these four Famiglias only.

Sawada Family:

Sawada Takayori: Vongola Decimo, son of Sawada Ieyoshi and Sawada Hikari

Sawada Tsukiyoshi: One of the three Bosses of CEDEF, has a Space Flame, adopted daughter of Sawada Ieyasu and Sawada Nana

Sawada Tsunayoshi: Second of the three Bosses, Sky Flame and firstborn of Sawada Ieyasu and Sawada Nana

Sawada Tsuruyoshi: Third of the three Bosses, Earth Flame and adopted son of Sawada Ieyasu and Sawada Nana

Sawada Teishiro: Candidate for Vongola Decimo, son of Sawada Iemitsu and Sawada Yuina

Sawada Teiryuki: Lawyer of Vongola Decimo, daughter of Sawada Iemitsu and Sawada Yuina

Story starts when Takayori is seven. There may/may not be a time skip.

Think of Rainbow Sky/Rainbow Space/Rainbow Earth as having nine cores, one for each Flame in Sky/Space/Earth Flames types. Rainbow would therefore have 27 cores.

Characters are canon unless it’s one of the OC Flames or OC Famiglias.
