Angelic Layer/WMG

Plot
=== Electronic Whips are illegal because they impede the goal of the Angelic Layer creator; mapping out the human nervous system. Game Breaker bugs were tolerated because they provided additional data. ===

Icchan created Angelic Layer as a way of both rustling up the cash for neurological research as well as getting data on the nervous system through how humans synchronize with their Angel dolls. Electronic whips were external components that had nothing to do with this connection, thus got in the way the original intent. Any bizarre unexpected superpower that nevertheless was the result of the unison of mind over matter was an opportunity to analyze a unique neural pathway.
 * Except that that's only in the anime. In the manga, his goal was just to create a fun toy.

Owning an Angel doll requires signing a document waiving privacy rights regarding neurological data.
Officially, it's stated (buried in the user agreement) that this is to avoid epileptics from having seizures and other problems.
 * Nevertheless, he was later sued for millions for using the data for his research. Fortunately his prosthetic grants and later robotics grants gained him billions.

Misaki will eventually suffer the same condition that her mother suffers from.
The main proof to this WMG is that while Hikaru moves like a super gymnast, Misaki is a Clumsy Girl. The huge offset between how well she can control Hikaru compared to her own body could indicate that she inherited the nerve disorder her mother has.

If Misaki had let Elaine fall when the layer started to vanish the match would have been declared No Contest.
Admitting the disappearance of the layer was due to a bug is the only thing Icchan would have been able to do that wouldn't make it look like he was allowing Misaki to cheat.

Icchan is Rozen.
Rozen made the first 7 dolls (the "Rozen Maidens") as prototype angels. Unfortunately, they were too powerful for the human mind to control, and had their own personalities, so he let them just battle it out to attain some position he made up called the Alice. He then forgot about/denied their existence, despite how much they worshipped him. Rozen changed his name to Icchan, so that the Rozen Maidens could never find him and perfected his doll-making skills so that he could make dolls that were a) controlable by the human mind, b) able to battle and, c) mass marketable.

Icchan is Dr. Warski.
Both have the same actor. Both created angels. Both.
