Special Note: This book has already reached 600,000 words, so there's no need to worry about it being abandoned. The confirmed worlds it will involve are *One Piece*, *Battle Through the Heavens*, *Naruto*, *Hunter x Hunter*, and *Berserk*. Other worlds are yet to be determined. The beginning is a bit slow-paced, and all the main characters are the protagonist's fathers.
