Run Alongside
There's a tsunami coming, so you put your fins on, open your mouth wide, and try to run alongside it.
えん
そ
None
You're able to run alongside the tsunami for about ten seconds before everything ends (えん).
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.
