Appearances
- Pre-Lunatics (mentioned only)
Nomenclature
- Kurogane river (Pre-Lunatics)
Notes
- The Kurogane river wasn’t identified by name until Pre-Lunatics was published in 2016. On its own, the name was unremarkable, however, the Kurogane Kingdom was instrumental in the plot of dance in the dark, a manga which SUDA51 and Syuji Takeya had previously launched in 2015.
