I think a lot about the designs of Senku's inventions. Depending on the level of technology available to him, the materials and finishing touches can change quite a bit. (If you're curious, Senku's at level 3 in this volume, which would be early industrial revolution.) But the most important factor is Senku's heart. What's he thinking? How much consideration does he give the villagers and their lives? I try to imagine his feelings and put them into the designs.

For instance, take Tsukasa's freezer apparatus shown above.

No matter how long the voyage takes— despite the passing seasons and earthquakes and changes to the waterfall— Tsukasa's device has to maintain a constant temperature, so that's how I designed it.

"Even while I'm away, Tsukasa will remain safe."

That sentiment of Senku's went into this design.

The Dr. Stone anime has begun! And it's all thanks to your support. The anime is so fun that I find myself watching it over and over and over.

The image above shows an ad from the city streets back when the anime was screened in the U.S.

I guess you never know where Senku is going to pop up at this point.

Get excited!
