Dear Hikaru,
This is a species of Marionia which I am calling Marionia sp. 2 on the Forum. it belongs to the family Tritoniidae, many of which eat soft-corals. They are often found on soft corals and their colour and gills make them quite camouflaged. This species is not uncommon in the Indo-West Pacific but there are a number of names given to similar animals and until we sort out how many species there are it is probably best not to use the names.
Best wishes,
Bill Rudman
