Those who are aware of the story of Dandadan agree that at first glance, two important characters in the show, Granny Seiko and Turbo Granny, have distinct personalities and are quite handful themselves. Therefore, the most logical dynamic should not be them being friends or even getting along peacefully.
One is a blunt, food-obsessed, TV-loving medium who believes in yokai but not aliens; the other is a foul-mouthed, speed-obsessed spirit who once threatened to devour Okarun’s family jewels. Even when they met for the first time, both of them were hostile towards each other as Seiko was performing an exorcism. And yet, according to the latest chapter in Dandadan, we are made privy to a conversation between these two ladies.
It’s becoming increasingly clear that these two old ladies might actually be real friends. The kind that care for each other and have an understanding to have each other's backs. While the conversation shown between them is incredibly short, it threw readers off the loop because no one saw this dynamic being formed.

Turbo Granny entered the story as a full-blown antagonist, a spiritual parasite feeding off fear, trickery, and teenage hormones. Seiko, being the seasoned medium she is, handled her like any nasty yokai: stern exorcism, no nonsense, no sympathy. But something interesting happened after she was defeated.
Seiko didn’t throw her out; rather, she was taken in and made sure to feel welcomed. It’s the most “Seiko” thing ever in Dandadan. She is shown to talk roughly, act unfazed, but quietly care about everyone under her roof, even if it is a terrifying yokai cat with an unfiltered mouth. Over time, this living arrangement turned into something that wasn’t just tolerable, it was domestic.
Turbo Granny in Danddan eventually is shown to be lounging around the house. Seiko is cooking takoyaki at high speed. She is even shown complaining endlessly, yet eating everything. They argue like old pals but refuse to part ways. And neither will ever admit they enjoy each other’s company. This is peak Dandadan energy, as no one in this story has been open about their feelings.
The truth is that they are already best friends in Dandadan

Even with conflicting beliefs, conflicting personalities, and a history built on curses and chases, Granny Seiko and Turbo Granny have something special. Their bond is what happens when:
- Two stubborn women refuse to show vulnerability
- But quietly choose each other anyway
Fans have been calling their relationship sisterhood, sismance, bromance, or even describing it as the funniest friendship in manga. But what matters in the end is that it’s real. And the more we see them, the more obvious it becomes: these two would risk everything for each other, even if they complain the whole way.
Final thoughts
Granny Seiko and Turbo Granny in Dandadan share a dynamic that’s comedic, emotional, and strangely intimate, something only two chaotic old ladies in a paranormal comedy like series could pull off. They’re not romantic nor rivals, and they are definitely far more than simple allies. At their core, they’re two lonely adults who’ve stumbled into an unexpectedly deep companionship while protecting the next generation in the way they know best.
Turbo Granny doesn’t do dramatic speeches, and Seiko can’t express gratitude if her life depended on it, yet when it truly matters, like Turbo Granny casually showing up to check on Seiko, where they talk like old friends, they move in perfect sync, acting like true partners. This is Dandadan at its finest: heartwarming chaos disguised as comedy.
