Read the full guide below to learn what happened to momo ayase parents, with canon-safe details and the latest updates from ComicK.

Does Momo Ayase have parents?

The story shows she has lived with her grandmother, Seiko Ayase, since she was young.

Manga flashbacks reinforce this by depicting Momo’s childhood with Seiko while her parents remain absent and never appear.

What happened to Momo Ayase parents​?

In Dandadan, the only clearly established fact is that Momo’s parents are not part of her life, and she has been raised by her grandmother, Seiko (Hoshiko) Ayase, since she was young.

Several reputable anime write-ups describe Momo as a girl who “has no parents” and is being raised by her grandmother

Explicitly stated in the story

In the core narrative, Momo’s background is communicated in a short, blunt line: she says she doesn’t have parents.

Importantly, that phrasing is deliberately open-ended: it does not automatically confirm whether they died, left, or are estranged—unless a specific localization makes it explicit.

Raised by her grandmother

The manga/anime repeatedly positions Seiko Ayase as Momo’s guardian and primary caregiver, which is why Seiko is the “family authority” in Momo’s daily life and why the home environment revolves around Seiko’s rules and spiritual practices.

Flashback context commonly focuses on Momo’s childhood with Seiko, while her parents remain off-stage.

Mystery remains

The story has not provided confirmed specifics such as: how they died (if deceased), when they disappeared, who they were, or what role they may play in larger supernatural/alien lore.

This “missing backstory” fits Dandadan’s broader approach: It uses mystery + emotional gaps to reinforce themes like found family and character-driven bonds formed under extreme paranormal stress.

Dub/localization note

Some English-language discussion points to certain localizations (and the English dub, per widely repeated summaries) that make the line more explicit (e.g., “my parents are dead”).

However, the commonly cited framing is that the original statement is ambiguous and the dub may clarify it more directly.

Theories exist, but they are not canon

Fans speculate about everything from neglect/estrangement to supernatural involvement, but these remain unconfirmed until the manga/anime provides explicit evidence (names, flashback reveal, or direct exposition)

The canon-safe takeaway is that Momo’s parents are absent and unexplained, and the story keeps their fate intentionally vague, What happened to Momo Ayase parents.

Where are Momo’s parents?

In Dandadan, Momo Ayase’s parents are not shown or involved in her day-to-day life, and the story keeps their situation intentionally unclear.

Multiple widely read character guides agree on the same core point: Momo has been living with her grandmother, Seiko Ayase, in the absence of her parents, but the series does not publicly lay out a confirmed timeline, cause, or names.

What the story makes clear:

• Parents are “off-stage”: They do not appear in the household or present-time scenes, and official-style profiles treat them as absent rather than active characters.
• Backstory is minimal by design: Most summaries explicitly say it’s unclear what happened, which is why the topic keeps trending.

Who raised Momo Ayase?

Momo Ayase was raised by her grandmother, Seiko Ayase, who functions as her guardian, caregiver, and primary family authority throughout the story.

Profile coverage repeatedly describes Seiko as the one who raised Momo “on her own” in the absence of Momo’s parents, and relationship summaries note that Momo has lived with Seiko since childhood.

Seiko’s role in Momo’s upbringing:

• Primary caregiver: Seiko is portrayed as the adult who runs the household and supports Momo through everyday life.
• Spiritual mentor/protector: Seiko’s background as a spirit medium shapes Momo’s childhood.

Seiko Ayase raised Momo from a young age, and the series keeps the parent backstory vague, so readers asking What happened to Momo Ayase parents are ultimately bumping into an intentional mystery rather than a fully explained canon event.
