You really were lucky to find it at Kourindou.

Although, if left like that, it probably would've been used to scam more unsuspecting fools.

Something this pure will easily get abused for people's desires, so it might've become corrupted over time.

Oh!

In other words... You bought that pot exactly so you could release the bird?
