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 squinted 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 is fond of making humans miserable through his ability.
Ake can make people's shoulders stiff by repeatedly hitting on them.
Ake sees Payn as his model to follow, and he is willing to listen to his speeches with passion.

In the anime
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.
Etymology
"Ake" is a corruption of ache.
"Katanori-kozō" translates as "shoulder-riding youngster," while playing on katakori (肩凝), "stiff shoulders").
"Algio" is a corruption of algia (Pain related to body parts like shoulders or knees).
"Autschi" is a cuter version of "Autsch" (ouch), so it could be literally translated with "Ouchie."
Origin
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.
Trivia
Ake's "random" nicknames are: "Brakey," "Edwin," "Gumball," and "Starman."
Out of the different-looking Yo-kai that were first shown at the Level-5 World 2011 trailer of Yo-kai Watch, Ake was the only one to not have its design changed.
