Enen no Shouboutai, Dr. Stone Recommendations
Both Dr. Stone & Fire Force have amazing OST's and character designs. Both require the same time investment and are high intensity Shonen shows with intriguing plots. These series also complement each other being watched together weekly as they have different strengths but enough similarities that fans of one will likely also enjoy the other. The change of pace between these shows can be refreshing while they still appeal to the same target demographic.
Permanent change. Dr Stone and Fire Force both follow characters that go through a drastic change from what was their regular life order, into a new craze of a world.
Once stable lives of MCs Senku and Shinra have been turned upside down by some uncontrollable phenomenon. Dr Stone has humanity become stone statues. Fire Force is Shinra's family perishing in a house fire.
Both are good shounen anime with Dr Stone using science and brains for the base of enjoyment, Fire Force using action.
