Charybdis

The Charybdis is a monster that lives fixed to the bottom of the sea in a nesting hole like an acorn barnacle. They don’t turn into something and set a trap, but due to their nature, they are classified as a kind of Mimic. It is said that there is another dimension conjured from the magic that extends inside their nesting holes in the same way as other Mimics. Condensed mamono mana is contained within their bodies, so they occasionally release it through holes in their exoskeletons. Due to this, air bubbles often rise from their nesting holes.
