Chapter 204 (Online)

Carrying the title Fully Recovered, this chapter marks the start of the Supreme Hero Arc and follows Suiryu after his release from the hospital. On the way out he runs into the Great Giant Anteater menacing bystanders and takes the creature apart without difficulty. His first instinct is to sign up with the Hero Association, since that is where Saitama can be found. That plan falls apart the moment he watches Wavygyaza casually crush the Emperor Giant Anteater.

Wavygyaza declares that her time away has left her reborn far stronger, and that she now intends to work as a Neo idol who also handles hero duties. Swayed, Suiryu switches targets and decides to slip into the Neo Heroes instead, boasting that he can come and go from the group whenever he likes. Back at the hospital, Suiko is annoyed to learn that Suiryu checked out without a word to her. Once inside Neo Heroes Headquarters, Suiryu is directed to the exam hall and handed a battle suit, which he promptly breaks. The damage leaves him on the hook, obligated to work for the organization until the cost is paid off. There he crosses paths with Metal Bat, Sekingar, and McCoy, the last of whom is patched in remotely. McCoy tells Metal Bat that Suiryu is set to take up a Neo leader role.

The chapter's Japanese title is ぜんかい (Zenkai). It first ran on August 22, 2024, then saw a republished release on June 19, 2025, and puts Suiryu and Saitama on the cover. The material draws in part from webcomic chapters 125 and 126.
