Not included in the tankobon release, it's the tech-toy promotional chapter: The Men Who Created AIBO (Game Creator Biography Special Edition)

Each chapter follows a strict structure, in which the the main character, a game creator, announces the concept of a groundbreaking game. At first, the staff members are against it, but later agree to develop it after being persuaded by the protagonist's enthusiasm.

Then a prototype is completed, but it's never good on the first try and he has to be re-done from scratch. After the release date is set and the game completed, the protagonist is confident about the quality of the game but worried if the audience will embrace. Of course, the chapter ends with the game becoming a groundbreaking hit.

The stories are exaggerated with typical shonen manga tropes and comedy scenes, with a significant part seems to be fiction; despite this the series has received numerous parodies and homages in the years following its publication.
