Werewolf Lord Through The Multiverse

Werewolf Lord Through The Multiverse (Start In Twilight),

MC dies and reincarnates in Twilight with a mission from ROB. Destroy the volturi. If he completes his mission, he can travel to the worlds he actually wants to travel to like Fairy Tail and maybe One Piece later.
This is my first fan-fiction, so constructive critisism is welcome.
There will be NO harem, so don't ask for it. MC will be with Alice, and she will join him on his travels.
