When Merlin was a child, his teacher thought that as the successor of Radiance, besides learning to cast spells with his hands, he also needed to learn to cast spells with his toes to truly be considered all-powerful. Thus, he forced Merlin to only use his toes to cast spells during school hours in the church. At that time, Merlin, who was still an excellent student, had to take off his shoes every time he was selected to demonstrate on stage...
That day, all the little girls who had a crush on Merlin found out—
The heartthrob had smelly feet.
Under such wonderful childhood influences, Merlin designed the Stitched Life Toe Worm!
The smaller toe worm represented Merlin as a child, while the larger one represented him as a young man—his teacher, even after Merlin had grown up, still wouldn't allow him to use his hands against the Esoteric Sect Followers!
