The main characters are likely to be the ones from the original Twilight series, like Bella, Edward, and Jacob.

It's possible that the main characters are a group of outcasts in the Naruto world. They are the shifters, and the dark moon is their only chance to gain acceptance or prove their worth. Among them could be a young ninja who has a special connection to the dark moon and can control the shifting abilities of the group better than others. There might also be a villainous character who wants to use the power of the shifters during the dark moon for his own evil purposes.
A werewolf might be a great main character. He is cursed and during the blood moon twilight, he has to struggle to keep his humanity while also protecting his pack from hunters who are more active during this time.
