Fleuri Jodeau
As the serpent's upper body bloomed, Fleuri, having been situated just behind where the base of where it split apart, was struck by the expanding wood and knocked back towards the rear of the snake. He didn't seem to be injured, but it did knock him off his feet.
Never thought I'd get backhanded by a plant, he thought to himself as he pulled himself to his feet and and realigned his helmet's eye slit. He quickly realized that the blow was a stroke of good fortune, for it had knocked the knight away from the path of the magical projectiles being expelled towards those still in front of it.
The others were striking at the front, so Fleuri would attack the rear part. He lunged forward and swung his sword horizontally into the serpent's bark skin, intent on slicing through and leaving the creature with a long gash. If the heart wasn't where he struck, he hoped that he'd at least be able to discern which direction- forward or back- the heartbeat was coming from.
