A gas mask with excellent performance that prevents even odors that cover the entire city. At the same time, high-level technology was used to make breathing easier, but it is regrettable that after the cause of the odor has been removed, there is no need to use it.

[iRO Description]
A high-performance gas mask that even blocks out the stench affecting the entire city. Unnecessarily advanced technology is used to facilitate easy breathing. It's a shame that this mask will no longer be as useful as it is now once the cause of the stench is removed.
