Ake evolves into Payn when fused with a Buff Weight.
Ake is a diminutive Yo-kai with a gray-colored body with thin arms and legs and a large green-colored round head. His eyes are squinty and have purple star-shaped markings around them, with the left-one being larger than the right-one. A permanent bared scowl is his default expression.
Hot-tempered, Ake was fond of making humans miserable through his ability.
Ake can make people's shoulders stiff by repeatedly hitting on them.
Ake appears inside the Old Mansion in Blossom Heights.

Ake makes his debut in EP022, along with Payn. The duo tries to make Nate's shoulders stiff, but to no avail. Payn then cheers Ake with an "old-master" speech, and the two resume their try, without success. They give Nate their medals shortly thereafter.
Based on the meaning of his Japanese name, Ake could be based on the Obariyon, a youkai from Niigata that likes to ambush people along roads by jumping out from bushes and onto their backs, crying out its own name (which is Niigata dialect for "gimme a piggyback ride!"). He will then become heavier and heavier until the victim collapses, or chew on their hair and generally annoy them. One source tells of a particularly strong man who managed to carry the ever-heavier youkai all the way to his house and throw him against a rock in his garden, shattering his body and scattering a pile of gold coins onto the ground. Alternatively, the gold coins will instead be a gift from the youkai himself if the victim puts up with his pestering all the way to their home.
"Ake" is a corruption of ache.
"Katanori-kozō" translates as "shoulder-riding youngster", while playing on katakori (肩凝り, "stiff shoulders")
