Mary felt fairly stupid as Souta reminded them that they were in a hallway. The bookcase her back was currently pressed against was the farthest point left in the room. That wouldn't allow for much maneuverability. Souta began running to the dome, while the abomination began sucking in. It's horrible gaping maw revealed a pulsating vortex of blue. Books started flying off the shelf, being sucked into the Monster's form. Mary too, felt as if she was being pulled by it. She began running towards the exit, her half-demon speed aiding her sprint. Akoni and Midori decided to stay with the being a little while. Akoni stayed behind to work defense. It seemed the slimy, undulating monster was trying to charge up another beam, and so he set up a gate to redirect the beam. Midori, seemingly attached to the old man, spewed fire at the monster. Mary was slightly confused at this unabashed show of the child's demonic nature. She simply assumed that the child was, well, a child, and didn't care much about appearances or decency. As Mary sprinted backwards, past the two who were staying back to protect her, she fired some shots at the creature, aimed so they would hit not the mouth, but it's flesh, if it could be called that. She needed to judge what material it was. It seemed to have some form of chitinous spikes, as well as ectoplasmic appendages. Hopefully neither would be too sturdy, but she had a feeling that this fight would be hard-fought even if they were.
