Klein didn't directly teleport back to 160 Böklund Street. Instead, he went to sea with Enuni, found a secluded spot, and chanted the honorific name of The Fool.
Then, he took four steps counterclockwise and went above the gray fog. With a beckon, he summoned a paper figurine.
Immediately after that, he picked up one of the Cards of Blasphemy on the long bronze table in front of him, and he placed it inside his body.
Klein suddenly had an additional dark red robe. This appearance seemed to look like rust and settled gunpowder that had been stained by copious amounts of blood. As for his face, it was covered by a dark gold mask. The patterns on its were ancient and set off a contrasting appearance with the crown he wore that was embedded with gems that sparkled red, blue, and green.
This was a change that the Red Priest card brought about.
