The perfect ending in the Sekiro game is Dragon’s Return. For specific ending conditions, please refer to this article’s list of conditions for achieving the perfect ending of Sekiro. So what are the triggering conditions for Sekiro’s perfect ending? Please read on for specific strategies!
1. The perfect ending in the game is Dragon's Return. First, you need to get persimmons, fresh persimmons (obtained by killing the White Snake) and dried persimmons (obtained from the White Shrine). You need to ask for rice many times until you become like a child. Feed her ordinary persimmons. Ordinary persimmons can be bought at the shop in front of the training path in Xianfeng Temple, and they can also be dropped by the monkeys in Xianfeng Temple. After eating the persimmons, she will give you Kuro's rice (one seems to be enough). Give the rice to the prince to make peony cakes, eat them in front of the prince, and go back to thank the son of Bian Ruo.
2. You need to defeat the spiritual monk who broke the precepts (in the Aquatic Village) to obtain diving skills, and get the Insect Sutra under a lake in Xianfeng Temple. Give the Insect Scripture to the Son of Bianruo, then refresh the map, go to the Hall of Illusion, and talk to the Son of Bianruo. She will ask you to find Master Xianfeng's Book of Return of the Dragon, which is a purple monk in the cave behind the main hall (note that this book will only be available when she asks you to find it). It needs to be completed before defeating Sakura Dragon.
