'Sona' tried prying open Sona's hands, but aside from the ability to amplify negative emotions, she didn't have any real power here, "H-how...?"
Sona slowly freed herself from the latches of darkness and even found a way to materialize her glasses before replying while making eye contact, "How, you ask? I thought we shared the same feelings and thoughts, but that doesn't seem to be the case when you've manifested like this. Of course, it's because I acknowledge you as part of me. An irreplaceable one even."
'Sona's' face became even more mired with confusion, "T-then... H-how...? Guhh..."
If she had accepted her, she should have already drowned in hate and jealousy. She couldn't understand how she was able to pull herself back.
"The moment my mind became clear, I immediately understood that all the negative emotions in this space are amplified beyond my control.", Sona explained with a light smile, "I won't deny that I didn't feel hate nor jealousy, since you can't multiply anything if there's nothing, however, you seemed to have forgotten that I could also feel rage."
'Sona' thought for a moment before chuckling wryly, "I see... You've indeed accepted me. I feel happy but also complicated that you can acknowledge me that easily."
'Sona' finally understood what pulled Sona out of the darkness. It's the same negative emotions that she used to sink her in, not aimed at others, but the fury at her own thinking, offsetting the other negative emotions.
And 'Sona' was indeed correct. Sona is resentful of herself. She's resentful at the fact that 'Sona' could even suggest taking the other girls out. Since 'Sona' is her own darkness, she knew she had these passing thoughts deep inside her, even if just a little bit.
Even though she had come to terms with the darkness residing in her heart, she couldn't easily forgive herself, 'I should really be honest with everyone... I guess I'll have to talk to and apologize to them after this.'
Sona then slowly put down 'Sona', letting her go. She already guessed that she can't really do anything to her aside from giving her suggestive ideas that would boost her negative emotions.
Looking around, Sona didn't know what to do next and could only look back at the hole depicting the outside world. From what she could understand, she had already transformed into something monstrous and gigantic as she threw various attacks towards Kisuke and Serafall. Strangely enough, she knew how to do all those attacks instinctively.
"It's no use.", 'Sona' suddenly voiced out after nursing her throat, "You might have been able to clear your mind, but the negative emotions swirling inside of you haven't disappeared. You're actually in an even more dangerous state as the 'rage' you are using to keep me in check, may cause you more harm than hate and jealousy. See that monstrous form? That's the result of it."
Sona immediately turned to her with a look of surprise and 'Sona' couldn't help but reel back seeing that, "...What?"
"I'm just astonished that you're worried about me."
Without beating around the bush, 'Sona' admitted it, "As I've told you earlier, I meant you no harm. I only wanted you to be 'released'."
Sona wanted to talk more to her other self, but she didn't have much time before the initial push that cleared her mind collapsed under the burden of all these negative emotions stacking up upon each other.
But even after a seemingly long time, Sona's face only worsened and staggered as she endured the non-physical pain that threatened to reduce her to nothing.
"Without alleviating these negative emotions, you won't be able to leave this place. This is your darkness and this is what's keeping you in here. If you don't let go of yourself, then both of us would just be destroyed, leaving an empty husk that only knows how to rampage until its eventual demise."
"I know that!", replied Sona with an agitated voice, "But I won't allow it! I'm a person, because I can keep my desires and darkness in check! Without it, I'm no different from an unthinking animal!"
'Sona' smirked at her response and said, "My~ How harsh~ But it looks like you can't think straight anymore."
"...What?"
"Letting your desires rage on is also one way of getting out of this, you know? How exactly? Don't ask--- !?"
Before she could finish her sentence, however, the both of them suddenly felt a familiar warm fuzz on their lips. The both of them then hurriedly turned their heads towards the hole and saw Kisuke's face with his eyes close up close.
Witnessing this, 'Sona' couldn't help but click her tongue and smile wryly, "This bastard... His timing is too good. To think that you'd be treated like a princess right now? I didn't expect that from someone who doesn't really understand a woman's feelings."
Turning her head again, 'Sona' herself was blankly staring at the hole while touching her lips and sighed, 'So this is goodbye. She may be smart, but she's a big idiot too. You really couldn't control feelings, huh?'
Sona straightened her back and a small smile of a maiden in love painted her face before facing her darkness, "I'm sorry, but I've got to go. I want to experience it first hand."
"Fuck off!", yelled 'Sona' back, "You don't have to tell me, and you really look like an idiot right now."
Sona only chuckled, as she grabbed on to these warm feelings, and went on for a happy walk towards the hole that is now covered in white light and starting to swallow the darkness.
'Sona' watched her as she approached the hole and light that was swallowing her world, but before she could leave, 'Sona' reminded her, "Don't ever think that I'll just disappear. For as long as you live, I won't ever leave your side, waiting for the day I can take over."
A large smile then appeared on her face before continuing, "Though if you need strength, I'm always willing to give a hand."
Sona stopped her steps and momentarily turned back to her, "If such time were to come, I'll give myself to you."
'Sona' watched her get swallowed by the light and disappear but not before chuckling, "You really are an idiot."

It has been several hours and dawn was about to break since Sona started her rampage. The formerly harsh world of sand has now become a world of frost and ice, with Serafall freezing Sona whenever she got the chance.
Within each hour, some transformation would take place on Sona's body, and right now, she has hundreds of black water tentacles sprouting from her back that extend to become gigantic and swing around like giant saws.
"What do I do, Ki-tan?" Serafall suddenly voiced out with a complicated expression.
"Hmm?"
"I don't think I have a way of defeating Sona-chan, as she is right now, even if I want to with my full power..."
"Well, you do have bad compatibility with her. While you try to immobilize everything, she would just keep on moving. That's just how bad 'flow' counters your abilities. If it's something like Sirzechs-san's Power of Destruction, then Sona wouldn't have a chance."
Pausing for a bit, Kisuke added, "And by the way, the situation isn't looking good right now. If she keeps going like this, she'll strain her soul beyond the point of recovery and might actually die."
"Say what!?"
