Chrome (クロム Kuromu) is the alleged sorcerer and future scientist of Ishigami Village. Originally a rival, he grew close to Senku as the de-petrified human taught him the art of science. He is one of the protagonists of the series. Having been fascinated with nature's resources since a young age, Chrome was always interested in experimenting with different materials despite having little to no knowledge about humanity's achievements and compounded scientific knowledge over thousands of years.[16] As part of the Kingdom of Science, Chrome serves as the unofficial right hand of Senku; this trust is what makes him one of the Five Wise Commanders. He is also the only post-petrification human among them. Gifted in both natural science and inventing, Chrome tends to alternate between making chemicals with Senku and building with Kaseki.
