A tsunami is coming, and you want to walk over it, so you have to ford it. You don’t walk across a tsunami, you wade across it.

Your ability to ford this tsunami impresses everyone who witnesses it, especially the Shougun (しょう). Now that you've taught him a tsunami can be forded, he's going to start sending his troops through them instead of waiting for them to pass.
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.
