Rance/WMG

Rance is either not his real name, or he never had one to begin with.
It's actually short for.
 * He is Inexplicably Awesome, so maybe.

Rance will become the Demon King in Rance 9

 * This is so he will be able to . Unfortunately, With Great Power Comes Great Insanity. Rance 10 will involve Rance's descendents killing him. What better way to make sure the Rance series ends then to kill the eponymous character?
 * Alternatively, he ends up going on a Suicidal Cosmic Temper Tantrum, possibly from.

Rance's 10 fated ones are introduced one by one through each game.
We already know that Sill, Shizuka and Kanami are fated for him. Word of God has stated that there will be 10 Rance games in total, and that Rance most likely has 10 fated girls. Rance 10 will involve all 10 of them joining together for something massive.
 * The first game, we were introduced to Kanami (and technically Sill)
 * The second game, we were introduced to Shizuka.
 * Third game, the girl could be either Sel or Leila.
 * Fourth game... Sanakia?
 * Fifth game would most likely be Rizna.
 * The sixth game, either Uruza or Magic.
 * Sengoku Rance, it could be any of the route girls, or Kouhime.
 * Rance Quest I'm not so sure on. Maybe Sachiko or one of the Kalars? Or maybe Crook, judging by Magnum.

Rance has subconscious mind control powers.
You tell me how you can THROW ROCKS AT SOMEONE (Sengoku Rance after Kenkoru is turned into a Demon) and make them like you more. Plus it explains why all the women love him after he has his way with them.
 * Better yet, Rance is Haruhi. Someone had to say it.
