Ukyo Saionji

Ukyo Saionji is a key character in the anime Dr. Stone, originally a modern-era survivor revived by Tsukasa Shishio. He starts as a high-ranking member and scout/head lookout in the Tsukasa Empire, where his exceptional hearing (honed from his pre-petrification job as a Japan Maritime Self-Defense Force submarine sonar operator) makes him invaluable for detection and reconnaissance.

In the anime adaptation, Ukyo is portrayed as a slim, toned young man of average height with short white (or silver) hair, blue-green eyes, and round, boyish facial features that often carry a calm, laid-back expression. He typically wears casual post-stone world clothing like a baggy orange top (sometimes with a paper cap in some depictions) and fitted pants.

Personality-wise, he's pacifistic and strongly prefers non-violent solutions, often advocating against unnecessary bloodshed and leaning toward clever tricks (like those from Gen) instead of force. He's rational, intelligent, kind-hearted, and highly reliable—eventually defecting to join Senku's Kingdom of Science as one of the Five Wise Commanders, where he handles intel gathering, security, surveillance, and serves as the group's "ears" thanks to his superhuman auditory skills. He also becomes skilled with a bow and arrow in the stone world.

Overall, Ukyo stands out as the level-headed, conscience-driven strategist who balances the group's more aggressive members while providing crucial support through observation and precision.
