I read the translated version of this manga in my country language about 8-9 years ago, and the translated books didn't have the name of author or original Japanese name.

The story is about an android (name 8 in the translation with an 8 number on his forehead) that was sent to a princess in some kind of virtual world as a birthday present, in order to become her bodyguard.
The 1st Act is about his fight and victory over the Demon King, who kidnapped the princess, as well as introduced 4 other male androids (named 0, 2, 4, 6).
The 2nd Act begins with the appearing of 5 other female androides (named 1,3,5,7,9) sent to compete with 5 male androides. And the translation stopped right there.

Have anyone ever read this manga? The translated name is "Rubik 8" (maybe because 8 appeared inside a huge rubik), but I doubt that this name is corrected.
