Turbo Granny is a yokai that acts cruel, sadistic, and is extremely foul-mouthed. She is also rather somewhat vulgar, as she offered Okarun a chance to suckle on her breasts in exchange for consuming his family jewels. Since she possesses impressive running power, Turbo Granny takes great pride in her speed and refuses to be underestimated.

When challenged to prove herself, she is not above using trickery to get her way, having been deceitful with Okarun and Momo in their game of tag by counting irregularly. Despite her negative attitude, she is revealed to have a compassionate side, as Seiko stated that Turbo Granny would most commonly wander off to spirits of girls who died tragically in order to comfort them, which was the reason as to why she fused with the Earthbound Spirit Crab within Shono City.
