Alternate
When your scooter has a fault, you need to get an alternate. Hopefully your insurance will cover it too.

The alternate scooter is made entirely of 鉄 (てつ). It's hard and cold and not very comfortable when you sit on it. That's why you chose to keep it as an alternate and not as your everyday scooter.
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.
