Time To Subdue A Devil

"Don't we have fun together, Mags? You really want to do this? To your oldest, best pal?"
Abab's words, that rang inside her head, made Mags want to laugh and gag at the same time. Fun together? Oldest, best pal? Bullshit. Thanks to Abab Mags had missed out of many things, she couldn't date or swim or sometimes even put on clothes properly thanks to the demon's mood swings and now he actually wanted her to give up on the first and probably only chance she had to get back some control?
"Shut up Abab. You know what I'll do if you start messing with this and you know I'll do it."
Mags answered Abab inside her head, but didn't even bother glaring at her arm and just kept her eyes on the book before her. Ignoring was what worked on Abab the best. But this time it only irritated the demon, and suddenly Mags' left arm began grabbing at the book, trying to snatch it away. Mags pulled the book away from his grip, and for a while Mags looked rather amusing, basically wrestling with her own left arm for a demonology book. But it ended, when Mags stood up and walked over to her bag, which was at the other end of the table. And as they got close a very uncomfortable feeling spread inside Mags' body, and her left arm began aching. Abab stopped resisting, and instead the arm fell limp by Mags' side. She looked down on it with a frown.
"I told you I'd do it."
Inside the bag there was a crucifix, a holy item that was able to get Abab under control.
"Now behave, because I will make this charm whether you want it or not."

Magdalene turned to look at the door when it was knocked on, and her classmate Chloe walked in. She was someone Magdalene had asked for help in this project, since Magdalene hadn't studied here for so long yet and didn't know where the best research materials were. And Chloe knew a lot more about demonology than her, being part demon herself.
"Ah, yeah, thanks a lot."
Magdalene said with a grateful smile, but she blinked, confused at Chloe not having any books despite having said found the right books.
"Uh, where are they...?"
Magdalene asked carefully, trying not to sound pushy or anything, since Chloe clearly was tired for some reason. Mags wasn't going to ask, they weren't nearly close enough for her to be asking how Chloe was doing in her personal life.

"Huh? I'm holding up just fine, but Abab is being a little bitch, like always. Just before you walked in he almost ripped a book and I would've been to one to pay for that."
Magdalene said, trying to sound bit lighter, since Chloe probably didn't need any more doom and gloom in her life, by the looks of it.
"He really doesn't want this charm to come into existence, can't blame him though."

"I don't feel like I owe him anything, yeah, but we were something like buddies before he pulled this shit on me. Can't help but feel a bit bad. Just a bit."
Magdalene explained, and sighed. Her left arm was now entirely limp, Abab had closed himself off and was now sulking. He probably wasn't even listening to the two anymore. Which was just fine with Mags, and she ignored the demon lord and after glancing at her arm focused back on the conversation.

What Chloe did with her tattoos was weird but cool, and Mags watched it with fascination. So she could store things in her body? Were those tattoos a kind of seal for it? Mags kind of wanted to ask, but lost the chance when Chloe kept talking and naturally Mags listened. So demons could be possessed too...
Mags felt for Chloe, she constantly lived in slight fear and anxiousness, thinking what would happen if Abab overpowered her and possessed Mags' body completely. It was scary, and Mags never wanted to experience that. She didn't want to kill Abab or anything, but if that would end up being the only way to gain freedom...
Mags stopped herself from thinking about it.
"If you were able to break free then that gives me hope that I can too. And this is the first step. Thanks for that, for giving me hope and helping me."
Mags said, and smiled at Chloe. Maybe they could even become friends. That'd be nice, Mags was feeling kind of lonely and Abab's company really didn't help with that.

Chloe really was big help, when Mags opened the book the girl recommended she saw that Chloe had marked chapters that Mags hadn't even realized were relevant and there was really useful information on each chapter. Mags' expression brightened and she looked at Chloe.
"This is great! I knew asking you was a good idea, thanks a bunch. I'll be able to make some real progress with this. I might even be able to produce a prototype by the end of the month."
