A new demon against Muzan, an ally for some, a personal enemy for others. Yushiro isn't happy, he hates having to share space with another demon, and on top of that the new ally believes themself worthy enough to speak to Lady Tamayo! Unacceptable.

You feel a look of pure hatred on the back of your neck as you try to study some medicinal plants that Lady Tamayo entrusted you with.
