Intercept
You're riding your scooter toward your yurt as fast as you can because someone is trying to get in there to boil your water and you want to intercept them.

さえぎ
None
This person you intercept turns out to be a shaman (しゃ). The shaman was just about to open the door to your yurt when you crash right into them.
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.
