Umio is the first protagonist of the story. 

He is also the newest male employee of the Horse's Bone bookstore - so he doesn't yet have a descriptive nickname like the others. Umi, as most of his friends call him, is a capable illustrator. Because of that talent, he is usually the first to lend Master help with her manga. 

Appearance-wise he wears glasses and has black hair. He lives alone in an apartment one train station away from Master's apartment.


The "youthful bookstore comedy" revolves around the folks who work in a manga shop deep in a certain "Electric Town" neighborhood. ("Denki-Gai" or "Electric Town" is a popular name for shopping areas that specialize or used to specialize in electric and electronic items, like Tokyo's Akihabara.) The protagonist Umio works part-time at "BOOKS Umanohone" along with his senior at work (but not in age) Hiotan. As many dedicated manga fans visit the store, there is always something going on.

Umio is a shy kid who just started his part time job at a manga store smack dab in the middle of the city. But his lifestyle isn&rsquo;t as glamorous as the neon lights that illuminate the city. Umio&rsquo;s closest friends are his co-workers who are all unique characters, to say the least, and although they're nice people, they have their quirks. They are a tight knit group of friends, have nicknames for each other and spend their weekends inside, sheltered from the extravagant scene happening on the outside.
