Mana-eater (Vanity Pet)

A rparasitic starving creature that acts much like an unborn infant, following around it's owner and in constant need of attention or it will give up on survival and die.
These creatures are very rarely found and often obtained out at sea in the midsts of mass fishing expedites.
It's reported that this pesky little creature gnaws away at its owner's energy and, despite how it may act, this creature will never grow out of its feined infancy stage - making them a very unpopular pet even with their rarity. Tatsukoi have noted a striking similarity to Beastblood Moonstones... But the correlation between the two is still unknown...
