Why are the rabbit girls so mad at Clownpiece? Not too familiar with Touhou, please explain to me!
The motif of the American national flag adorning her clothes is actually a deliberate provocation to the Lunarians, who associate the flag planted on the moon by humans during the Apollo mission.
But I don't know why Tewi is here.
(Clownpiece herself is a provocation to the Americans with her spellscard like Fake Apollo/Apollo Hoax Theory by the way)
