Impass evolves from Noway starting at level 29. As of Yo-kai Watch 3, he now evolves from Noway when fused with a Granite Stone.
As an evolution of Noway, Impass is a white wall with a extended bottom part covered in stones. He has a navy blue roof with two golden ornaments and wears grey zori sandals. Impass seem to have the same facial features and long arms as his pre evolution.
Like Noway, Impass will always refuse commands. However, unlike Noway, reverse psychology does not work on Impass.
In the 2nd season of the Mr. Nyanpachi series, Impass is shown to be Noway's father. He constantly points out to Mr. Nyanpachi the troubles happening to Noway, such as anonymous doodles on Noway's back.
