Lizzo has gone full anime for Halloween 2026, dressing as Seiko Ayase — the grandmother character from the hit anime series Dandadan. The singer’s costume was featured in W magazine’s roundup of the year’s best celebrity looks, updated on October 28, and it delighted fans of the series, who recognised the homage instantly. Seiko Ayase, known in Dandadan as the spirit medium grandmother with formidable powers and a no-nonsense attitude, is a fan-favourite character — tough, stylish and deeply protective of her family. Lizzo’s take on the character continues her long tradition of ambitious Halloween transformations, which have previously included everything from Baby Yoda to a mozzarella stick. This year, she chose a character with cult credibility rather than mainstream obviousness, and anime fans rewarded her for it.
Anime takes centre stage this Halloween
Lizzo’s costume reflects how thoroughly anime has entered the celebrity Halloween mainstream. Dandadan, with its mix of supernatural action, comedy and family bonds, has become one of the most talked-about series of recent years, and Seiko’s blend of glamour and grit makes her a natural costume choice for a performer of Lizzo’s confidence. The look also fits the pattern of Halloween 2026, in which stars have favoured specific, character-driven references over generic spooky outfits. From Uchis’ film homage to Bailey’s cartoon recreation, the season’s best costumes have been the ones that show their wearer’s taste — and Lizzo’s Seiko is among the most knowing of them all. For fans, the message was clear: Lizzo does not just wear a costume, she commits to it. Seiko Ayase would surely approve — and would probably have something sharp to say about it, too.
