Redesign of an older character, Taro.
She was an extremely greedy cat in her mortal life; tricking and stealing from every owner she had.
Then one day she was tracked down and killed by a vengeful previous master and she became a preta. Now she has an insatiable demonic appetite and has to eat/absorb energy constantly otherwise she will grow too weak to keep this form and will revert to a spirt/wisp-like shape, left to drift around aimlessly until she regains her strength again.
