Androids and robots have become common place for people to own, though most are used for work and cleaning there is a select brand that has been built for one purpose, to fight one another for human entertainment and amusement. These known as SCbots (Specialty Combat Robots) and SCaibots (Specialty Combat Artificially Intelligent Robots)

Tomo is one of those models, in fact he was first SCaibot model who dominated the World SCbot Competitions for four years straight before his owner 'The Crimson Masquerade' decided to retire from the sport.

This year though, the patent on Tomo's AI programming, the factor that placed him above his competition during his championship run, has run out, and now SCaibots just like him are being custom built in unbelievable numbers for people wanting to take part in the new SCaibot battles all over the world. Always one to accept a challenge 'The Crimson Masquerade' also joins in.

Unfortunately for Tomo the rules and ways of playing the SCaibot games have changed, so much in fact that upon entering the games once more, Tomo's owner decides that his SCaibot is too outdated to handle the rounds, and replaces him with several new models.
