Science is family
Family, by scientific definition, refers to people who share a connection to you. Whether by blood, DNA or marriage.
There is also the unscientific definition. Family refers to people you feel the closest to. A friend. A lover. A mentor. The people you share with your lowest, and highest moments.
Family is treasure, according to the great historical pirate, Edward Newgate.
Dr Stone as a manga, is more than just about the Science. It also focuses on the connections between people, which makes for some really beautiful writing.
For example:
(i) To You, 3000 years from now
9 chapters into Dr Stone, we get a glimpse of Senku's backstory with his father, Byakuya Ishigami. Ever since he was a little boy, Senku has been fascinated by Science. Even making it his dream to go to space one day. His father realized his son's passion, and since that day, he has done everything in his power to support his son's dream.
Even going as far as establishing a village for his son 3 millenia into the future, so his son wouldn't be lonely when he revived from the stone casing:
In his dying days, Byakuya spent them collecting platinum from the river bed, so that the petrification formula would be completed by his son.
So that by the end of it all, humanity would be revived
(ii) Heat Heart
Kaseki is the resident old character/sage of the Dr Stone verse.
As a resident of Ishigami village, he is the craftsman of the village, having designed things such as the bridge leading up to the village, Kohaku's shield and even Kinrou and Ginrou's spears. Though, in all his years working at the village, he has never had a kindred spirit. Someone who he could really share his passion of craftsmanship with. That is, until Science was introduced as a concept to him.
(iii) A Sister's love
Kohaku, the lead female character of Dr Stone has a sister called Ruri. Though, for as long as she could remember, Ruri has constantly been sick and bedridden, which has caused Kohaku to watch out for her sister.
She purposefully misbehaves, all so that her sister will be made the village shamaness, and have a reason to live on.
Of course, Ruri does get saved later through Science, and the two sisters managed to work things out with their father. Additionally, Ruri does manage to grow closer to her love interest through Science as well
(iv) Tsukasa Shishio
Initially an antagonist, before eventually becoming an antagonist, he has some of the best character interactions in the series. Like with Senku:
And his sister, Mirai. The reason why he became a pro wrestler was to raise money for her surgery, since she was brain dead. His little sister also loved the little lady mermaid, so he wanted to make her happy by collecting sea shells for her.
Even after fighting with Senku, reconciliation between the two was possible:
Of course, just like with adventure, there is the flip side of the coin when it comes to family. Family is always there to support your dreams, no matter how bizarre they are. Yes, even if your dreams are as minuscule as taking over a village:
Or quite literally, taking over the world
