The World of Substitutes: My Substitute Is Nagato

I like Joj's Stand, One Piece's Devil Fruit, Naruto's Bloodline Limit, Gourmet's Prisoner's Gourmet Cells, Death's Zanpakutō, Full-time Hunter's moves… Not across all realms. There are manuscripts saved, 30+ An ark of civilization, one-tenth the size of Blue Star, appeared out of thin air and fell from the sky. The impact caused large-scale crustal movement on Blue Star. Countless cities and humans were destroyed, and the number of people was only one-tenth of the original number. Along with the fall of the ship, there were countless black stones carrying alien viruses. The virus infected all living things on Blue Star. Some people could not bear it and mutated into monsters, while others awakened the ability called avatar. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
