This anko is discusses the yukkuri mindset of those who can't take it easy e.g. Reimu can't sing well, Alice can't coordinate well, Patchouli's rule isn't easy, etc.
Of course, then there's Meiling who can't speak, which is important to how yukkuris greet each other.
Story-wise, the Meiling kills a Reimu, causing the Patchouli to die of shock. The remainder Marisa, Chen and Myon try to stab it, but Meiling's Ki training not only prevents the piercing, but she releases a Ki shock that numbs them.
Then she smashes the Marisa into the air, and it explodes into paste.
Two humans are watching, and they comment on Meiling's strength, which surpasses even Remiryas and Flans. However, cleaning up is a problem.
