Dr. Stone Wiki

Suika (スイカ) is a descendant of modern humans and an inhabitant of Ishigami Village. She's one of the main protagonists of Dr. Stone.

Suika initially was ostracized for her clumsiness and constant usage of a watermelon helmet due to her nearsightedness, she quickly makes friends with Senku, who doesn't judge her immediately by her appearance and later helps her regain normal sight through lens.

Suika later serves as a scout for the Kingdom of Science, being proficient in stealth.[11]

As of the New Stone World Arc, Suika has switched to becoming a scientist with Senku as her mentor.


Suika Icons

Suika is a young girl of short stature with blonde hair in a bowl cut, being described as cute by many of the other characters. Kohaku especially considers Suika adorable, and says so on several occasions.

She has to wear a helmet made from a melon rind to help her see better because she has a disease called "blurry sickness", or in modern terms, near-sightedness. Senku created a pair of glass lens in her helmet to help her eyesight. She wears a dark-blue poncho that reaches to above her knees and wrists, and she has a large white rope attached to her neck like a necklace, which is common for her tribe, especially for girls. Her shoes, unlike most of the villagers' shoes, are flat as she does not have the strength or agility to use the heeled part yet.[12]

When Yuzuriha created a shop, Suika wore a modern-time dress.[13]

After being revived in South America, she uses her blood to carve the same E=MC2 that Senku has onto her poncho as a symbol of trust that she has in her friend and mentor.

During the timeskip while the rest of the world was petrified, Suika aged and her appearance changed considerably. She is now taller, with her hair having grown longer with two stands resembling a watermelon stem. Her face slightly resembles Kohaku's, but Suika's lips are a bit fuller. She wears a similar outfit to the one she wore in her younger years but more fitting for her age, including the heeled villager shoes.[14] Her poncho is the same one from before, but the dye has faded to a lighter shade, and her shoes are a combination of what Senku wears and the village's design.[15] She still wears the lower half of her watermelon as the top half broke during the battle against Stanley's crew.


Suika is a caring, inquisitive individual with a talent for spying.[11] She seems to be a little shy mostly because people saw her as weird for wearing a watermelon over her head (revealed to be because she has bad eyesight, and looking through the watermelon allows her to see a little better due to the pinhole effect). She's become one of Senku's closest allies ever since. She's moved when Senku doesn't ask her about the watermelon she wears or calls her weird for wearing it[16] (though it was most likely because he doesn't care).

Once Senku makes glass lens for her using the watermelon head, she's grateful for him fixing her eyesight, and declines to get more "normal practical" glasses, opting to keep her watermelon helmet. She's shown to be brave as she purposely leads the Tsukasa Empire troops away from the village by using herself as bait. She also enjoys helping Senku and her friends. For example, when Senku needs volunteers to spin thread, she immediately volunteers herself and the other kids, stating that she would prove they could be useful.

As a kid, Suika is curious and enjoys exploring. Also, she occasionally doesn't understand some of the more "adult" topics discussed such as wondering what the village sisters mean when they say boyfriend or wondering what a harem is.[17] Nonetheless, she has proven to be intelligent as she managed to understand Gen's path and his message based on some flowers he left behind. Similarly, she is observant enough to understand that Kinro has the same bad eyesight problem she has after she watched him fight for only a few minutes.

Suika is quick to make friends and is incredibly kind. She immediately becomes friends with Mirai and states how happy she is to have a female friend her age. She also wants to be of help to others and dislikes it when she can't help others. She is also very compassionate as she saved Charlotte (an enemy soldier) from dying of a poisonous bite, despite putting herself in danger of being captured.

Suika seems to have a fondness of animals, like having a pet dog named Chalk, and bonding with a pig that Francois planned to use as an entrée, to which Senku and Francois relented and allowed her to keep it as a pet, much to her joy.

Suika has proven to be very capable as she was able to gather food for herself in Brazil for several years. She is also very determined as she overcame consistent failures of creating the revival formula until she was able to revive Senku.[18]

Abilities and Equipment[]

  • Stealth Master: Suika is trusted by Senku and his friends to let her go on scouting. She is able to roll herself inside the melon hat, allowing her to recon deep into enemy territory undetected. Suika is able to slip past through hostile units when she snuck past Tsukasa's men and gave Gen the knife that he used to sabotage Hyoga's spear, attempted to retrieve the mobile lab from Perseus after the whole crew, with the exception of her and Ginro, are petrified by Kirisame. She is highly dependable when it comes to scouting. Senku even placed her with Tsukasa, Hyoga, and Ukyo to infiltrate Xeno's castle.
    • Due to growing up and having her melon broken, Suika can no longer perform this skill.
  • Knowledge of Forests and Animals: Suika is stated by Francois to be the foremost expert of the forests and animals surrounding Ishigami Village. Because of this, she was able to foraging the jungles of Brazil and survive for years, in spite of being alone. This showcases great survival skills for Suika and proof of good instincts.[18][19]
  • Intelligence: Suika is intelligent and observant, quickly deducing Kinro was losing the fight against Magma because he is nearsighted like her and he couldn't judge the proper distance to attack him. The greatest display of her intelligence is that she used all of the lessons taught to her by her friends to overcome being alone in brazil. She was even capable of re-creating the revival formula after years of consistent failures before she was finally successful.[20]
  • Amateur Doctor: Suika was taught basic medicine by Senku. She is knowledgeable enough to help Charlotte when she was bitten by an spider from the Amazon.
  • Speed: Since Suika got her glasses she is able to be quite quick which comes in very handy for stealth and especially for outsmarting enemies, as shown when she confronted Tsukasa's soldiers. While not as fast as other characters, she has shown to be speedy enough to get back from being tied up by Mantle to witness the match between Kinro and Magma. She was also speedy enough to outrun adults such as Tsukasa's soldiers, Hyoga, and Homura. Her speed ability proved invaluable when it came to rescuing the science lab from the ship after it was overrun by the Petrification Kingdom.
  • Luck: In contrast to Senku and how much bad luck he has, Suika is noted to have amazing luck when it comes to certain feats, as shown when she successfully found tungsten among Chrome's rock collection and when she discovered the Medusa floating in the water.
  • Crafting and Building: During Suika's survival in Brazil, she is capable of building a hut on top of the medusa tower along with a boat used to gather the bird droppings just off the shore. She is also able to craft herself clothing such as shoes, as well as a shield which is shown on her back after Senku has been revived.

  • Suika's name is the Japanese word for watermelon.
    • This comes from the watermelon Suika wears over her head, which comes from a plant of the species Citrullus lanatus, bearing a melon-like fruit.
    • It's unknown if Suika had a different name before donning her helmet as everyone in her village is typically named after minerals and Chrome comments that "Suika" may be a nickname.[21]
  • Suika is one of the most popular characters in the series, ranking in the top ten in every popularity poll she is in.
  • Suika tends to refer to herself in the third person in the manga. However, after growing up, she seems to have outgrown this habit.
  • Suika's melon helmet used to have faint stripes, but after rolling around so much they got rubbed off.[22]
  • Suika's melon has gone through several iterations through the series, at one point the stem and leaf was purposefully replaced with a horn shaped leaf to aid her hearing while eavesdropping on conversations while hidden. [23]
    • Subtle changes to the melon's design can even be seen at Suika's introduction in Chapter 21 in contrast to her original appearance as pictured in Chapter 17 with the rest of the villagers. This original appearance had smaller eye holes, a smaller stem and a differently shaped leaf. The crack in the melon also originates from the middle, above her mouth rather than on the side of it.
  • Kaseki was the one who made her original watermelon helmet.[4]
