Batman and Shimizu killed Doomsday after Superman’s Kryptonite weakness left it vulnerable, but Shimizu discovered that its cells were still multiplying and that it was adapting to the radiation.

After the Hashira agreed to Kagaya’s plan to kill Muzan, Shimizu tested and injected a serum that transformed him into a demon-like life form without the usual weaknesses. He survived sunlight, gained greatly increased strength and Chakra, and discovered that his new blood-related ability let him teleport to a drop of his blood.

The Corps celebrated Shimizu’s succession as Lord Master, while he left for Tokyo to help Shinobu Kocho prepare for childbirth; the story then shifted to Shimizu’s renovated home in the Naruto World.

• Shimizu swallowed Chiyo’s Ration Pills as his body transformed overnight, greatly increasing his vitality and Chakra reserves.
• After carefully adapting to his new strength, Shimizu went to the training grounds to test it and met Pakura, who asked what was wrong.

• Pakura told Shimizu she had awakened Scorch Release and asked to spar.
• Shimizu took Pakura to the unfinished training grounds beside the Emerald of the Wind and opened its barrier.

• After several hours, Pakura sat panting while Shimizu said he had used only a little Chakra.

Shimizu taught Sunagakure ninjas five Breathing Styles, a broadly accessible Nintaijutsu, and the Third Kazekage recognized how much Shimizu’s contributions strengthened his claim to become Fourth Kazekage. The chapter left Shimizu summoned to help preserve the Breathing Styles and plan how to cultivate practitioners.

• Shimizu demonstrated five Breathing Styles and gave Sunagakure ninjas textbooks, ordering them to keep the techniques secret.
• A Special Jonin told the Third Kazekage that the Breathing Styles were a powerful, widely accessible secret art that could greatly benefit sword-wielding Jonin.

• The Third Kazekage summoned Shimizu to record the Breathing Styles in the Secret Scroll of Sand and plan how to cultivate talent for the system.

Shimizu and the Third Kazekage established a tiered plan to train and protect Sunagakure’s Breathing Style practitioners. At the Puppet Force, Sasori described a promising but incomplete method for creating Human Puppets that retained their living abilities, and proposed using a captured Uzumaki with the Mind’s Eye of the Kagura as a relay for remote puppet control.

• The Third Kazekage agreed that Shimizu would train the current group for a year before Sunagakure established a permanent Swordsmanship Improvement Class and a broader selection system.
• Shimizu left the Kazekage’s Office Building and returned to the Puppet Force, where Sasori reproached him for neglecting his work.
