An extravagant spinoff drawn by none other than Boichi Sensei!

My only job was supervising character dialogue, and it was a task I performed with gusto.

Anyhow, this is a completely original tale from Boichi Sensei. Sort of a "What if?!" story that takes place in an alternate universe, separate from the main Dr. Stone series. And within that grandiose plot is Rei the robot, who makes for a valiant and adorable hero! I got to enjoy this as a reader, just like you. Hopefully they'll make merchandise!

The time spent putting together this spinoff felt short to me, but it was still intense and meaningful. It was my first work in Shonen Jump where I was also in charge of writing the story, and it's also Shonen Jump's first sci-fi series that makes use of hard sci-fi rules and principles. It even contains chapters without any humans.

What's more, it's the product of consulting with a real-life astronaut who actually rode in a Soyuz module and visited the International Space Station.

I'm beyond grateful to everyone who made this challenge possible, including the editorial department, my editor and of course Inagaki Sensei.

And naturally, I'm grateful from the bottom of my heart and then some to the readers who gave me a change to work on something so moving and full of joy. I've gotten so much support from all of you!

I have to confess, I feel the same way about you readers as Rei does about Byakuya. I hereby dedicate this work to those with the spirit to draw, those with patient souls and everyone with feelings buried deep inside their hearts.
