Suika is introduced as a little kid, and most fans and reference sites put her at about 9 years old when Senku first arrives in Ishigami Village in Dr. Stone.

Quick answer

  • When Senku first meets her in Ishigami Village: Suika is around 9 years old.
  • A bit later in the story (around the Pegasus-building part of the manga/anime): she’s about 11–12 years old.
  • After the big multi‑year timeskip (when the world is petrified again and she revives Senku): her chronological age is around 15–18 , but her body is usually described by fans as more like mid‑teens (because some of that time she was petrified and not aging physically).

So if your question is just “how old is Suika Dr Stone?” in the early series, the best short answer is:

She’s about 9 years old when we first know her in Dr. Stone.

Why there’s confusion about her age

Fans argue a lot about Suika’s age because of:

  • The series’ timeline (years after the petrification event).
  • The extra time she spends petrified during the later arcs.
  • The big timeskip where she lives alone and slowly figures out how to recreate the revival fluid over several years.

Some discussions point out that you can call her chronologically around 18 by very late story events, but physically she’s clearly portrayed as a young/mid‑teen, not an adult.

What the community usually goes with

From fan timelines and forum breakdowns:

  • Born around “year 5730” in the story’s in‑universe calendar.
  • Age 9 when Senku arrives at Ishigami Village in year 5739.
  • Around 11 during the Pegasus‑building period (around year 5741) and roughly 11–12 soon after.

These numbers are assembled from timeline clues rather than a single explicit line where the manga says “Suika is X years old,” which is why you’ll see small differences (11 vs 12 vs “early teen”) in forum and Q&A answers.

Mini FAQ

Q: Is Suika ever officially stated to be 11?
Some Q&A and trivia sites say she’s “around 11” as a rounded figure for her early adventures with Senku’s crew, but this is more an estimate than a hard canon birthday line.

Q: Is she really 18 at the end?
Chronologically, counting all the years that pass, she can be argued to be around 18, but because part of that time she’s petrified, many fans say she’s only physically around 15–16.
