Mira Cerulean

Mira Cerulean (ミラ Mira) is one the five Domekeepers of the Neo Octarian Army and a user of various water-based weaponry. She is the monitor of the Water Dome and a minor antagonist of Inkling Uprising. She the final Domekeeper encountered by the NSS, and is fought by Petra Yeager.

Mira takes advantage of the Inklings' (and Octolings') weakness to water, and created a new fighting style based off water, which she likes to call "Lethal Hydration". She commissioned various inventors and designers to make special weapons to make use of the liquid and weaponize it, though only one accepted as the rest deemed it far too dangerous. She later requested armor to protect her from water in the event of an unforeseen accident. Because of this fascination, Valda assigned Mira as the Water Dome's Domekeeper.
