Hamagachi Katsuhiko

From Shadow Academy

• Sumeragi Kiyoshi's cousin, who he's staying with while he's in school.
  
• Katsuhiko is a senior at Sunida High and an aspiring mangaka. She currently writes and draws the popular shounen (though many of her fans claim its shounen-ai) doujinshi "Onmyouji Overdrive", as well as two online comics - a risque, shoujo-ai comic called "Parapara High School" and a light-hearted martial arts webcomic called "Fists of Glory".
• Katsuhiko prefers to live in homey clutter. Her wall is plastered with posters from her favourite manga and anime, as well as from a number of martial arts films, and the only space in her apartment not littered with books is her bed and drawing table, and sometimes the kitchen.
  
• Katsuhiko is pleasant and energetic. She likes doing fifty thousand things at once, and loves to cook - though she's not very good at it. She worries about Kiyoshi and likes to mother him.
