to meet two of his fans. He asks people to send faxes during his radio show any time they want someone to know something. He is upbeat and quite friendly, with noticeably bright blue hair, and even has the nerve to rub Mr. Handa's head and remark it is like a mushroom (a melon in the dubbed version). DJ 623 is also a character in the anime Sgt. Frog named as "Saburo Mutsumi".

Frogs manga artist, Mine Yoshizaki, created the character concept designs for Seven of Seven. As such, various crossovers exist between the series. The character of Mutsumi Hojo, who appears as "Examinee 623" and the host of his own radio program in 7 of 7, is a major character in Sgt. Frog. Melody Honey, a minor character in Sgt. Frog, appears and even receives a backstory. Additionally, the recurring ghost character in Sgt. Frog very closely resembles the design of the ghost that appeared in the temple in episode 12 of Seven of Seven. In addition, episode 89 of Sgt. Frog features a plot that splits Corporal Giroro into seven personalities, most of whom resemble Nana's split personalities. A segment of the episode featuring Mutsumi takes place at the cherry tree seen frequently in Seven of Seven. In Volume 18 of the manga, a ninja named Nana is introduced. She looks identical to Nana from Seven of Seven. She also had six copies, each one with a personality matching the various Nanas from Seven of Seven.
