Mairead smiled evilly when Izumi picked her up, she had been waiting for just that. In the split second before Izumi's body slam the glow from Mairead's hand intensified until it was almost too bright to look at and vines burst through the window and wrapped around Izumi's ankles and legs, stopping her fall and throwing her off balance enough for Mairead to elbow her in the face and escape her grip. Mairead laughed as Izumi began punching her and clawing at the vines to get free, and only laughed harder when a punch made contact with her face.
The glow from Mairead's hand grew more intense as the vines began climbing Izumi's body, locking her legs and then her arms as she struggled to get free. With a smirk Mairead punched Izumi in the face repeatedly as her left hand began glowing red. By this point Mairead's eyes were black as she kicked Izumi over and willed the thorns to grow. As Izumi was falling she tripped Mairead and Mairead fell hard on the floor, her concentration was almost all in the vines. With a growl, Mairead stood up and put her foot on Izumi's chest as the vines wrapped around the prone girl's neck and head.
"All I gotta do is squeeze, Izumi. Her voice was cold and hard, and the glow from her left hand got a little brighter as the thorns dug into Izumi. She willed the plants to constrict the struggling girl more and more and the thorns to get longer until Izumi had almost blacked out. With a snap, Mairead's hands stopped glowing and she kicked Izumi's face until she was sure Izumi was unconscious and would stay that way for a while.
Mairead laughed and slid her daggers back in their hiding places before she wiped the blood from her mouth and the back of her head. She staggered for a second and had to lean against the wall but as she tried to catch her breath, she laughed again at Izumi and spoke in a much more lighthearted voice.
"Well, Izumi, ye did a good job this year. But never forget to watch my hands. And jus' so ye know, I didn't kill her cause that woulda made the year so much less fun." Mairead turned to a nearby camera and winked as she gave a two finger salute. With a deep breath Mairead turned and walked slowly to the corner dorm room, that's the one with the best view.
