The young Rainbow

Due to Kawahira wanting the Arcobaleno's to get along, he makes them forget who they are and get the mind of toddlers, then sending them off to a random location. Said place happens to be Namimori where they threaten a 15 year old Tsuna to take care of them until they get their memories back. Unknown to them, they asked the one and only hacker 27 and assassin Cielo for help.

Luce and Yuni are not included here or only briefly as they had a vision that made them think they should not involve themselves. Hopeful that the vision will fulfill itself so the lone sky will no longer be left in the dark.
