木野村 透

The main character's childhood friend. With his father being a manga artist and his mother a cosplayer, he himself also grew to love anime and manga. Starts off as chubby like the main character but due to her influence decides to start dieting as well. He's always a bit timid or shy, blushing often when the character or Onii-chan compliments him.

He worries about the character on her diet and later he goes to the US coming back slim and as handsome as the others, after not being able to eat the food properly and coincidentally breaking his glasses and switching to lens.
