Suika’s age depends on which “Suika” you mean, because there are a few popular ones in anime and games.

Main possibilities

1. Suika from Dr. Stone (the girl with the melon helmet)

In the Dr. Stone timeline, Suika is about 9 years old when she first appears in the story.

Later flash‑forwards and fan timeline reconstructions put her in her mid‑teens (around 15–18) by the end of the manga era, depending on how you count the years she spent petrified.

Because petrification freezes biological aging in Dr. Stone, some fans also distinguish between her “physical age” (mid‑teens) and the number of years that have passed in the world.

2. Suika Ibuki from Touhou

Suika Ibuki is an oni from the Touhou Project, so she is not a normal human and her “age” is more mythic than literal.

Fans often connect her to the legendary oni Shuten‑Dōji, whose story is placed around the 9th century, which would make Suika well over 1,000 years old in lore terms.

In fan discussions, people usually just treat her as an ancient, ageless heavy drinker rather than giving a precise number.

3. Other or fan / VTuber “Suika”

There are also “Suika” characters in fan games, AI chat characters, and VTuber circles, where age is either not given or completely fictional and creator‑dependent.

In these cases, you have to check that specific creator’s bio or FAQ to know the intended age (if they state one at all).

Quick answer style (for your post)

If your post is about Dr. Stone:

  • You can safely say: “Suika starts the story around 9 years old and is in her mid‑teens (roughly 15–18) by the latest parts of the timeline, depending on how you count the petrification years.”

If it’s about Touhou’s Suika Ibuki:

  • You can say: “Lore‑wise Suika is an ancient oni, often linked to legends from around the 9th century, so she’s well over a thousand years old, even if she looks like a small girl.”

If you tell me which Suika (Dr. Stone, Touhou, VTuber, etc.), I can rewrite this as a short, SEO‑friendly “Quick Scoop” blurb tailored exactly to your post format.
