Momo Ayase has mentioned her grandmother multiple times in the first two chapters of Dandadan. A spirit medium, Momo’s grandmother Hoshiko has a youthful appearance considering her age. She sports glasses, hoop earnings, and a high ponytail. Her style also suggest she deliberately seeks to appear younger. This includes wearing her a revealing sweater that displays her cleavage. When she works as a professional medium named Dodoria Santa, she wears a grotesque masks and a hooded black cloak. Her looks and body are hidden from view. Whether she hides her appearance to create a persona or assumes she won’t be taken seriously as a woman.

Dandadan Chapter 3,” A Clash of the Grannies, Huh?” open with Hoshiko telling the fortune of a young idol. She predicts his age is 27, he claims he’s 20. She predicts he love curry and have a wife and kids. He basically claims she a fraud. Hoshiko arrives home just in time to prevent Turbo-Granny from eating Momo. Armed with a bat, she challenges Turbo-Granny , who quickly appears behind her. Turbo-Granny is set on fire and becomes trapped in a barrier circle created by Hoshiko. The barrier will ignite the demon if it passes over the line. In combination with her “charm nails” she’s able to use her barriers to both protect herself and trap Turbo-Granny . Despite Turbo-Granny mentioning that Ken would die if Hoshiko sets her on fire, Hoshiko doesn’t seem to care.

Gotta play tag with Turbo-Granny

Momo wakes concerned for Okarun (Ken). She finds her grandmother watching Bakatono, and assumes she killed Okarun. Hoshiko leads her granddaughter to believe she killed Okarun. Hoshiko hasn’t seen Momo since she gain psychic powers and is clearly bitter over Momo’s previous dismissing of her psychic powers. When her grandmother tells her were Okarun is Momo rushes to find him eating in the shrine. She relived. After informing her grandmother that she has powers now, her grandmother reveals more information on the Turbo-Granny . Formerly called “100 KM/H Granny,” she used to terrorized Japan and Hoshiko investigated her inside the tunnel.

Hoshiko claims she couldn’t even get close to the tunnel due to strength of the presence. She explains that bound spirits “stay in a place they have some sort of strong attachment,” and are “strongest in their territory.” It’s foolish to take on a bound spirit inside their territory. According to Hoshiko, the bound spirit has fused with the Turbo-Granny. Even though her grandmother has warned her, Momo is still determined to rescue Okarun. Hoshiko tells her she will need to “play tag” with Turbo-Granny. It’s especially important that she get Turbo-Granny to leave the bound spirits territory. Once weaken, Turbo-Granny can be defeated more easily. Before that confrontation both Momo and Okarun need to get stronger. At the end of the chapter, we see that idol from earlier, Shouma-San is actually 27, has a love child, therefore proving Hoshiko is correct.
