Trivia

 * In the first release on Monthly Comic Alive November 2017 issue, the chapter has 22-page length. However, in ' and later, ' releases, it has 28 pages, which combined with 6-page mini chapter, labelled Room. 4.5, which was released in the next magazine issue along with Room. 5. This heavily implies the latter releases have the full content of the chapter due to its unfinished storyline, but was split into two parts under unknown circumstances.
