When it became clear to him that Gyokuran, his childhood rival, was completely obsessed with Mokuren, Shion decided to take advantage of this while sitting in the brig of the Moon Base by "getting to Mokuren first" in order to destroy Gyokuran's being on the most basic level. As a side benefit of this action, he intended to defile the sanctity of the Sarjalim faith, which had abandoned him so many times in the past, by ruining the last of Sarjalim's sacred avatars. And so, he struck a bargain with Mokuren when she came by to give him his lunch one day: "I love you, give up your Kiches powers (virginity) and I will reconcile with Gyokuran, no matter what it takes.". To this deal, surprisingly, Mokuren agreed. But during the act, Mokuren had a change of heart and resisted, but Shion did not listen and continued, effectively raping her. Afterwards, Mokuren took up ill and Gyokuran, enraged at Shion's perceived actions, demanded permanent exile for Shion. Mokuren, upon hearing of this, pulled herself together and declared that she and Shion had become engaged, and that Gyokuran would let him out of the brig NOW. At this pronouncement, Gyokuran was forced to release Shion from the brig, and Mokuren and Shion moved into Mokuren's quarters together. It is the confusion surrounding these events by all parties involved and not involved that leads to the underlying cause of the dark and terrible nature of the plot of the manga series.
