Million Yen Muffin (ConceptTopic, 14)

From Compile Worlds

The Million Yen Muffin is a large, delicious muffin valued at one million yen! Not much is known about it, other than that it had been made with delicate care by the Muffin Town shrine maiden Midori Mizuri before being transported to a low-security store for Doppelganger Arle to steal it. Exactly why this muffin is worth so much money isn't certain. Mitsuki promises an invigorating sense of power and delicious taste when eating it, and being made by a shrine maiden may also play into it.
