Akihiro Tsurumi is a male university student who attends the same school as the protagonist, Sakurako Umeyashiki. He is recognized as an attractive young man, though his defining trait is a notable difficulty with modern technology. This struggle with electronic devices and gadgets stands in contrast to the series central theme involving alien interest in home appliances. Beyond this technical challenge, his personality is further shaped by a deep love for animals, with a particular fondness for cats. This affinity for felines may create an interesting dynamic with the cat-like alien MuMu, though the specifics of their interactions are not documented. While his identity as a fellow student and his core traits of being technologically challenged and animal-loving are established, there is no information available regarding his specific role in the story, his personal motivations or goals, his relationships with other characters beyond being a classmate, any character development he undergoes, or any notable abilities he might possess.
