Kogasa-san, Kogasa-san! There's an interesting river over there!

Hwuh?

A muddy tributary joins up with the clear main current...

...but despite merging, the two don't mix. Instead, they flow along separated.

Really!

Why don't we go see it?

There's still a little rain falling, but...

Sure, let's go!♡

We're going to go check out the irrigation ditch out back for a bit!♡

Please don't raise flags like that...
