Dianyan in Yo-kai Watch 1

Dianyan and the other Gemnyans can only be obtained by scanning their respective Yo-kai Medal QR code at Piggleston Bank to obtain a Diamond Coin. Using it on the Crank-a-kai will award the Diamond Bell, which makes Dianyan appear.

Dianyan is in the northeast corner of Gourd Pond Museum's 2nd floor, which is located in Breezy Hills. He can be battled once a day until he's befriended through the regular method.
