Have
A narwhal and a moon is all you have. Imagine one of each under your arms.
You don't have anything else. This is it. All you have.
ゆう, う
あ
None
Everything you have (except the narwhal and the moon) were taken from you by a roving gang of youths (ゆう).
They came and took your things. Now they have all your stuff, and you only have the moon and a narwhal. You don't have much anymore, but at least you have these things still.
