Dr. Stone Reboot: Byakya spin-off manga series focusing on Senku’s dad Byakuya has been announced and will launch next week on Weekly Shonen Jump. The spin-off series will only run for 9 chapters and will be written and illustrated by Dr. Stone illustrator Boichi.
For those Dr. Stone fans wondering if you need to be up to date with the main manga series in order to read this spin-off series…you do not. The series will stand on its own but will supplement the main series of Dr. Stone’s main continuity.
