A wing is something you must not do anything with. Wings are fragile (think bird's wings and butterfly's wings) and sometimes dangerous (like the wings of a plane) and you must not touch them, or even go near them! You MUST NOT. You. MUST. NOT.

Apart from staying away from wings, the other thing you must not do is eat mochi (もち). Okay, they're not fragile or dangerous, but I love mochi and I don't want you eating them.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up whatever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
