"Tsuna, that world will be destroyed if something isn't done and if things continue like they are now, he will destroy this one as well as all the other dimensions. Everything my other self has done has failed to stop him. If I send you there I know you can stop him from bring that world to destruction," said Byakuran, looking implorable to Tsuna, the Decimo of Vongola for eight years.

Tsuna, a small male with the softest looking light brown hair and mothering eyes the color of milk chocolate, sat in a chair with a desk full of papers in front of him.

"Byakuran, I understand that this is something I should do. It's just that I don't want to leave my family behind," explained Tsuna.

"I know and I don't want you to do this either but this world, your alternate self isn't going to become strong enough to help that world. He will need a sky like you to pull him out of the dark future he is leading the worlds into; we can't let all the worlds be destroyed by him," said Byakuran in a dead serious voice uncharacteristic to his silly, sly attitude that he always shows.

Tsuna gave a sigh and said, "Byakuran, what will happen to this world if I leave? The world that Ghost came from was destroyed when he left and he wasn't exactly human when he got here."

"You will not be taking your other self place while he's alive or being a new person in that world, but you will be reborn. So, you will be human and live in that world naturally."

Tsuna just sighed and repeated the question he has been dreading to know the answer since Byakuran asked him to go to another world; "What will happen to this world, once I leave?"

"...I can't change that aspect of moving someone between dimensions; It will be like what happened to Ghost's world."

"I thought so..."

"Someday you will meet the me of that world and he will have all my memories from this world," said Byakuran, trying to counsel the brunette he has come to see as his sky.

Once again sighing, the Vongola Decimo looked up with a burning resolve in his eyes and said the words that he would later say was the best thing he had done for all the parallel worlds and for himself... After all he never wanted to be Decimo in the first place.

"I'll do it."
