Thegis

Thegis (ジーギス) is the test proctor for the Kingdom of Blumund's Free Guild branch. He was originally an adventurer in the combat division, but was forced to retire due to losing his leg. Thegis was in charge of Rimuru's adventurer test, approving the latter's certification as an adventurer after having seen his passing with flying colors. He eventually regained his leg after receiving a full potion from Rimuru, allowing him to continue his adventure activities.

Trivia

 * Thegis is one of the few characters whose appearance was completely omitted from the anime as Rimuru's trip to Blumund was skipped.
