While their teacher and classmates accepted to keep their secrets, they kept asking Touma and Ty things like why they go to school with them, why she was trying to become good and how he discovered it, annihilating any chance for sports this period.
Well… Except Cindy, who was infuriated by how everyone was only interested by the two otherworldly beings, even her cronies. In her mind SHE should be the one being the center of attention, ALWAYS! She didn't care that Ty was an angel, didn't care that God himself tasked said angel with helping Touma redeeming herself. One way or another, she would make everyone forget about them and be the only one the school look up to, as it should be!
Sensing a heart almost as corrupt than a demon's the last surviving piece of Naamah, a shredded hand, slowly crawl to the owner of that black heart to lightly tap their ankle. Sensing something touching her, Cindy looked down to see a black thing vaguely looking like a hand. Instantly understanding what it was she took it and, since everyone was far too occupied with Touma and Ty, got back to the changing room.
Once there, she said to the hand of Naamah: "We both want to make those two pay, so I propose a pact to you: Help me be the class' idol again, and until you take over Touma's body I'll lend you mine."
Normally, Naamah wouldn't even thing of taking over a pitiful human body, but right now she was more of a beggar than a chooser.
The charred hand crawled up to her head before planting the pointy tips of its fingers into Cindy's head. Then the hand dissolved into her, making the girl feel like her body was on fire while her skin progressively turned gray. The ever increasing heat prompted her to want to undress as fast as possible. It's only when she shredded her cloth trying to grab them that she realized her fingers now ended in sharp talons. She also had grown wings, horns and a tail all strictly identical to Naamah's ones. But that wasn't the most surprising change…
The new demoness couldn't determine where ended Cindy and were started Naamah, like their two minds fused into one. In fact, it's exactly what happened, and the new being resulting from said fusion absolutely loved it.
Using her powers, the new Naamah changed back into her human self and got back in class sensing that, thanks to her human part, Touma wouldn't be able to sens what she truly was.
