First, Welcome to the Wiki !, it's good to see more people who liked the anime !.
On if the anime will have the second season, really there are not many signs. When the manga of Mahou Shoujo Site ends, there may be some news from the author about the anime or about his next work.
Kichiro Misumi, is an antagonistic character of the series, to a certain point in history, where it passes to the side of the ´´good´´ for a good in common, which is to stop the Tempest.
The Tempest is a massive event, in which all human beings are converted into sperm to fecundate the King, who acts as a deity of the Earth, to create a world where humans have no malice, where hatred, Envy, grudges and other worldly feelings can not ruin the beauty of the planet. I know what I just described bizarre, but in the manga they explain to more details about the Tempest, its origin and its consequences. From Chapter 115 (ENTER 60) the Tempest begins.
