Rooms and Modes
Librarian mainly revolves around one two-floor library plus a post-completion Special Stage. The useful distinction is not enemy rooms; it is whether you are doing the main 3,072-book cleanup or the post-clear ultimate-skill objective.
| Room / Mode | Use it for | Route advice |
|---|---|---|
| Main Library | The main two-floor cleanup space containing all 31 shelf sections, the 3,072 books, the four keys, and the chests. | Treat it as two maps: first floor for 1A-1N and second floor for 2A-2Q. |
| Special Stage | Post-completion mode tied to Overtime Avoider and the ultimate skill. | Enter after the main clear and use the ultimate skill; do not route it like another manual main-library cleanup. |
