Yeah, posted those CS last night. ^^" Here's Sota's CS, and I've already posted the first IC post. I heavily implied that Kaika fell into the rift, and that Sota tried to grab her back out but also got pulled in.
----
Name: Sota Matari
Age: 17
Personality: Ever since he had been in control after his possession by Yasu, Sota had been very cautious and regretful on how he still has the dark presence. Yet, he sees comfort when he's with Kaika, who he has a relationship with. He tries to find ways to make up for what he's done when possessed by finding out ways to assist the others, but is afraid that he would just let Yasu take over again. So most of the time, he seems like a pacifist and restrains his newly gained "demonic powers" from having Yasu's darkness within him. Despite his regret and hesitation, Sota wouldn't stray away from doing the right thing, and doesn't want to be the one on the sidelines. 
Abilities: Due to be possessed by Yasu, Sota had inherited a majority of Yasu's powers: from darkness manipulation to having a very high rate of regeneration. He could use these powers without having Yasu take over, but using these powers too much could result with a possible possession again. Sota can use Yasu's signature weapon, a scythe named "Rupture Cresent," and seems to have great experience with it (Though, this could be just Yasu's experience with scythes being passed onto Sota due to the possession). His manipulation over darkness kinda works like Kaika's manipulation with life enery, being able to manifest darkness into a solid form. Sota's regeneration is a notable ability, the time it takes to heal his wounds is doubled by the darkness within him.
Weapons: Rupture Cresent, his scythe.
Other: None.
