One of two "agents" from the Magic Academy sent with a report about the Star Crystals' disappearance. Their true forms are unknown since they took the images drawn up by Haruna; Shichimi is a cat, and Motsu is a frog. They then stay at Mahora and keep a close eye on Negi to ensure his magic secrecy. Eventually, this may no longer be the case when all of class 3-A learn about magic and became Pactio partners. In more recent episodes, a few bizarre segments involve Motsu and Makie, where Makie refers to Motsu as "father". A few other strange cutscenes show them playing with tissue paper and bubblewrap. Occasionally, they are found with the Black Rose Baron.

Motsu appears to be based on Aboshi Frog, a character created by Mako Aboshi for the Pani Poni Dash! anime. (Both Negima!? and Pani Poni Dash! have Shaft as the animation studio.)
