- In the Viz Media Volume Release, there have been some changes in the chapter numbering:
- The original Chapter 32 also featured a full-color page, which was made black-and-white in the volume.
- Chapter 33 originally featured a flipbook animation that simulated a camera swooping down on Saitama within the Dark Matter Thieves' spacecraft. This was shortened in the volume release.
- Chapter 34 featured an additional double-page spread of Boros encountering Saitama after the latter defeated Geryuganshoop.
