Seiko Ayase's Plofile

■Official Profile
Momo's grandmother. Known as the spiritual medium Santaria Dodoria. A powerful figure capable of placing protective barriers, she offers advice to Momo and her friends.

■Seiko Ayase Overview
Seiko Ayase is the grandmother and guardian of Momo Ayase. She works as a spiritual medium under the name Dodoria Santa. Despite being a grandmother, she has a youthful appearance and proudly considers herself a “beauty witch.” Although her language is rough and direct, she has a warm heart and fiercely protects her granddaughter, Momo. It’s implied that she once beat up Momo’s ex-boyfriend in Episode 1, suggesting she drives away any man who tries to win over her granddaughter.

Seiko takes care of Okarun after he is cursed by Turbo Granny, and she seems to get along well with Turbo Granny, who now resides in the form of a maneki-neko (lucky cat statue). The two even go to the public bath together.

Seiko has a tendency to feed the younger characters, and whenever the chaos settles down, she often prepares meals like crab hot pot or hosts a barbecue party, serving up her delicious cooking.

What Are Seiko’s Superpowers?

Seiko calls herself a “fake medium,” but her skills are the real deal. She has been known to accurately guess the real age and personal circumstances of celebrities who fake their background, and she uses protective wards to shield her home from supernatural threats. Her reputation as a powerful medium is well-established in the spiritual community. She has even faced off against Turbo Granny on her own and occasionally travels as far as Hokkaido for exorcism work, leaving her home unattended.

Seiko’s abilities rely on borrowing power from the local guardian deity (land god), which means she cannot use her powers outside of the specific area. Because of this, she needs to make extensive preparations and perform rituals to pay her respects whenever she travels for work.

Who is Seiko's Voice Actor in the Dandadan Anime?

Seiko is voiced by Nana Mizuki, a renowned voice actress known for her roles in popular anime. Some of her notable characters include Hinata Hyuga in Naruto and Fate Testarossa in Magical Girl Lyrical Nanoha. In addition to her successful voice acting career, Mizuki is also an accomplished singer.

Seiko and Momo’s Relationship

Seiko Ayase and Momo Ayase are grandmother and granddaughter. While the story does not mention Momo’s parents, it appears that Seiko has raised Momo on her own since she was a child..

As a practicing spiritual medium, Seiko put Momo through special training, referring to it as “protective rituals (JP: Omajainai).” Although young Momo found this embarrassing, she later realized that the training was meant to protect her and was a key factor in awakening her psychic abilities.

Their relationship is a mix of strict discipline and deep affection. While Seiko treats Momo sternly, she cares for her deeply and always keeps a watchful eye on her growth. In return, Momo values Seiko’s teachings and strives to meet her expectations, showing her respect and appreciation.

Seiko and Okarun’s Relationship

The relationship between Seiko Ayase and Okarun (Ken Takakura) was built through her granddaughter, Momo Ayase. Over time, Seiko becomes a reliable figure for Okarun.

Early in the story, Okarun falls under the curse of Turbo Granny and loses control of himself. Seiko, using her extensive knowledge and skills as a spiritual medium, steps in to save him. She uses powerful warding techniques to restrain Okarun and successfully seals away Turbo Granny’s curse.

In gratitude for her help, Okarun tries to repay Seiko with the money he earned from his newspaper delivery job, intending to cover the costs of living and the clothes she provided him. However, Seiko declines the offer, saying, “What good would it do to repay me, you fool? If you feel indebted for the help you received, then repay that debt by helping someone else in need (JP: Otagaisama.) That’s what we call ‘mutual support.’” These words leave a lasting impression on Okarun.

Seiko and jiji’s Relationship

Jiji is Momo’s childhood friend, but he had never met Seiko before the events of *Dandadan*. As the story progresses, they meet for the first time. Jiji openly compliments Seiko, calling her "beautiful," and Seiko shows a rare moment of genuine happiness at his praise.

After Jiji becomes possessed by Evil Eye, Seiko steps in to address his spiritual issues using her expertise as a medium. During this process, Seiko recognizes Jiji’s spiritual talent and potential, and she takes on a mentor-like role, guiding and supporting his growth.

Seiko and Turbo Granny's Relationship

The relationship between Seiko Ayase and Turbo Granny has evolved significantly as the story of Dandadan progresses.

Early in the story, Turbo Granny possesses Okarun (Ken Takakura), putting him in a dangerous situation. At this point, Seiko uses her skills as a spiritual medium to separate Turbo Granny from Okarun and successfully seals her away. During this phase, Seiko and Turbo Granny are clearly in an antagonistic relationship.

Later, however, Seiko invites Turbo Granny into her home, and they begin living together. Seiko frequently cooks for Turbo Granny, gradually winning her over through her cooking. Over time, the two develop a close friendship, even fighting together as allies and coming to trust each other.

Today, Seiko and Turbo Granny share a relationship akin to that of family. In particular, the bonus episodes included at the end of the manga volumes showcase their everyday interactions, which have been well-received by readers for their heartwarming and humorous dynamic.
