Nazumi appears as a minor character in the anime SSSS.Dynazenon, moving within protagonist Yomogi Asanaka's social circle at Fujiyokidai High School. He sports brown hair and is occasionally seen in his school uniform. His distinctive black backpack creates a visual contrast with classmate Ranka's red one, a detail established when their belongings appear side by side in episode 1.

During a tense group moment in episode 12, Nazumi demonstrates support by placing a calming hand on Ranka's shoulder. This action occurs while the characters are gathered together, with Nazumi positioned at the group's right end.
