The Weight of Being a Teenager in Dandadan

Momo’s age matters because Dandadan constantly throws adult-level danger at a teenage girl who should be worrying about school, friends, and romance. Instead, she is dealing with aliens, spirits, curses, urban legends, and threats that ordinary people cannot even process.

Unlike many action heroines, Momo does not begin as someone who wants to become a fighter. She is dragged into danger through a bizarre argument with Ken Takakura, also known as Okarun. What makes her special is how quickly she adapts.

Momo’s powers awaken under extreme pressure, but the story does not make her fearless in a shallow way. She gets scared, angry, embarrassed, and overwhelmed. Then she acts anyway. That is what makes her courage feel human.

When readers ask how old is momo ayase, the answer gives more weight to her journey. She is not a grown exorcist with years of training. She is a teenage girl forced to learn through danger, instinct, and emotional resilience.

Who Is Momo Ayase in Dandadan?

Momo Ayase is one of the two central protagonists of Dandadan. She believes in ghosts and yokai but rejects the idea of aliens. Okarun is the opposite: he believes in UFOs and aliens but does not believe in ghosts. Their argument becomes the spark that pulls both of them into the supernatural world.

Momo comes from a family connected to spiritual power. Her grandmother, Seiko Ayase, is a spirit medium, and Momo’s own ability to sense and use spiritual power becomes one of the core forces of the series.

Her relationship with Ken Takakura starts from conflict, teasing, and disbelief. Over time, it becomes one of the emotional centers of the story. They trust each other because they survive the impossible together.

What Happened to Momo Ayase’s Parents?

Momo is shown living with her grandmother Seiko, and her parents are not central figures in the early story. The manga does not fully frame her parents as the main emotional mystery in the same way it does with some other supernatural secrets.

What matters most is how this family setup shapes Momo. Living with Seiko gives her a direct connection to spiritual belief, even though Momo has complicated feelings about that world at first.

Momo’s personality also makes more sense through this background. She is independent, sharp-tongued, emotionally guarded, and mature in ways that feel older than her age. She can be reckless, but she is rarely helpless.

This is one reason Momo is easy to empathize with even when Dandadan becomes wild or absurd. Beneath the aliens, yokai, jokes, and battles, she still feels like a girl trying to protect the people she cares about.

Momo Ayase and Ken Takakura: Same Age, Opposite Worlds

Momo and Ken Takakura are close in age and attend the same school, but their worldviews could not be more different at the start. Momo believes in ghosts but not aliens. Okarun believes in aliens but not ghosts.

That contrast is the foundation of their chemistry. Their first connection is not romantic softness. It is argument, curiosity, and mutual disbelief. Then the supernatural proves both of them right in the worst possible way.

Their dynamic works because both characters grow through each other. Momo becomes more open to ideas outside her comfort zone. Okarun becomes braver, more expressive, and more willing to stand beside someone instead of hiding behind loneliness.

Momo’s feelings for Ken develop slowly because they are built through action. He shows up. He tries. He protects others even when he is terrified. That is why her opinion of him changes from annoyance to genuine admiration.

Momo Ayase’s Age Across the Story

Format	Momo’s Age	Context
Chapter 1	Likely 16 to 17	First meeting with Okarun and the bet that starts everything
Early manga arcs	Likely 16 to 17	Awakening powers, facing aliens, helping with Turbo Granny’s curse
Mid-series arcs	Teenage range	Threats expand, friendships deepen, powers become more controlled
Later manga arcs	Teenage range	Momo becomes more decisive and more reliable in battle
Anime Season 1	Likely 16 to 17	Covers early material and introduces her core personality

Watching Momo grow from Chapter 1 onward is one of the most satisfying parts of Dandadan. She does not become powerful by losing her personality. She stays loud, emotional, stubborn, funny, and deeply caring.

Is Dandadan Manga Still Ongoing?

Yes, Dandadan is still ongoing. The manga is written and illustrated by Yukinobu Tatsu and is serialized on Shueisha’s Shonen Jump+ platform.

The series has continued to release new chapters, and the manga has already moved far beyond the material covered by the anime. That means anime-only fans still have a lot of story ahead if they choose to read the manga.

The anime also continues to grow. Season 1 aired in 2024, Season 2 aired in 2025, and Season 3 has been announced for 2027. That makes now a good time to catch up before more of Momo and Okarun’s story gets adapted.
