Spring has passed and the hot summer is coming.
Yukkuri Marisa energetically jumps in the forest while gathering food, something they call "hunting".
This is for her children who was just born in the spring, her beloved wife Reimu, and one more thing.
Soon, the couple will have a big duty waiting for them.
Rainy season is coming in early summer.
For yukkuri, water is their enemy.
If they're drenched for a long time, their body will melt and they take it easy forever (dead). To avoid that, during the rainy season, yukkuri confine themselves in their nest to hide from the rain. This is one of the yukkuri's habits; it's called "rain confinement".
