Is this garlic? The inflorescence and the vampire-castle point this way. Is Kuma a werebear?
Edit: It's Allium ursinum (German: Bärlauch), one of the english names being bear garlic or bear leek. The bear reference is found in other languages too. Folk lore says, that bears consume the bulbs after hibernation. That explains Kuma with a leek leaf on her head!
