Apart from the initial episode, when the first monster bled all over Bell, all subsequent monsters killed in this series all die rather bloodlessly.
Bell Cranel is known as little rookie due to how fast he achieved the second level faster than any adventure including the Sword Princess Ais Wallenstein.
Author Fujino Omori said that he doesn't want Bell's age to change. So the series takes place within one year.
Based on a Japanese light novel series written by Fujino Omori and illustrated by Suzuhito Yasuda. SB Creative has published nineteen volumes since January 2013 under their GA Bunko imprint.
The series adapts the first 5 novels of Fujino Omori's light novel series of the same title.
