The added charm of this game is that there's this big chute (しゅ) at the end. It's so charming because you love chutes.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up what ever 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.
