Mc is Sekiro. He will have Sekiro's memories and skills as he is Sekiro. There will be prosthetic tools hidden throughout the elemental nations. Upgrade materials will also be hidden everywhere. He will be given a gourd from Lady Emma, who will be a healer in this world. Kuro will exist, but he won't be a significant character. The sculptor will exist; he will be an ex-Kage-level ninja who has become a sculptor now. All bosses from the game will be present in this world, and Sekiro has to beat them again to enhance Attack power. Mid Bosses will also be present so he can increase vitality. He can choose to spare, either. There will be no fast travel or sculptors idol. He has to sacrifice prayer beads to any statue of Buddha. Dragon rot will be present in this world if he dies more than the number of resurrects before resting. The people suffering from Dragon Rot will be the ones he has met or has a connection with. To remove that, he will have to complete Emma's 'quest'. The time period at which he is inserted has not yet been decided. It will probably be after a Ninja War. This fic is still under development. Prosthetic tools will not have a limited use. The prosthetic is a divine armament containing all the prosthetic tools that the sculptor has installed. They will become available when he finds them and asks the sculptor to attach them. Since this is a different world, yes, he can prevent the demon of hatred.
