Bee
On the insect signpost there is a single sign that says bee.
ほう
はち
None
Thanks to the insect signpost you find the bee. You make it just in time to see the bee hatch (はち) from its egg.
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.
