Meowliangmaru is a young but cool-headed ninja who assassinates his targets by swallowing them whole.
Meowliangmaru is always hungry and never full, but he is able to carry out his duties as a ninja by licking the "black pill that satisfies hunger" that he carries with him.
Meowliangmaru is a voracious eater who never gets full and can swallow human and shikigami whole.
When a Meowliangmaru swallows a human or shikigami whole, its stomach expands to accommodate the swallow, making it unable to stand, and it sits down and strokes its stomach in satisfaction.
Meowliangmaru may vomit out any creatures it swallows that it is unable to digest, but it may also digest them completely.
