ABOUT Seiko / 01—06

01First appearance and background

Seiko appears in the early chapters of Yukinobu Tatsu’s manga, which began in 2021. Working as the medium Santa Dodoria, she can protect her home with a barrier. Her youthful appearance contrasts with her role as Momo’s grandmother; her place in the story rests on experience, giving Momo and Okarun someone to turn to when the supernatural stops making sense.

02Personality and appeal

Seiko speaks sharply and has the skill to back up her confidence. That combination gives her role as an elder a distinctive edge. As a reading of her character, her appeal lies in trust that does not depend on soothing words: she may be difficult company, yet her judgment carries weight. Her abrasive manner and genuine competence belong to the same memorable personality.

03Story journey

[Spoilers: anime episodes 3–5] After Seiko intervenes in Okarun’s curse crisis, Momo and Okarun head to the tunnel for a chase against Turbo Granny. A huge crab-shaped bound spirit complicates the confrontation, and victory does not resolve every consequence of the curse. Seiko’s training prepares them for the encounter, while the test of working together in the moment belongs to the two young leads.

04Relationships

[Mild spoilers: later in anime season 1] Momo is her granddaughter, while Okarun receives her help and guidance because of his curse. Momo’s childhood friend Jiji also seeks Seiko out after encountering a spirit in his new home. These connections make her both a family elder and a shared point of reference for young people dealing with unfamiliar supernatural problems.

05Versions and visual identity

The visual reference here is her everyday design from the 2024 TV anime: silver-white hair tied high with a red band, red glasses, a blue jacket with white sleeves, a pale yellow buttoned knit mini dress, a long dark shawl and light-colored slides. The shawl’s burgundy lining echoes the glasses. Her tall hairstyle and broad silhouette project authority, while the sandals keep the look casually domestic. Page illustrations are unofficial AI-generated fan art based on the anime design.

06Fan interpretations

Original fan reading for this page: Seiko’s barrier can be read as a tangible shape for “home.” There is an adult who understands the supernatural inside it, yet outside the door the youngsters still have to run, decide and cooperate. She gives the story somewhere to ask for help. Set beside the pressure of her training, that security makes her a reassuring elder who also asks others to grow.
