The Dionaea continued to remain idle.
With the time limit over, Professor Port clapped his hands as he exclaimed, "Alright, students! It is time for you all to face this beast. Remember, the green pads around the room will bounce you right off the walls in case it sends you away from it. Good luck, students!"
After his announcement, he took a deep breath.
At his signal, the loud noise of the glass box being moved erupted across the room. With the box sliding down, the lid opened itself as the Dionaea was freed from its transparent cage. It squirmed, finally showing a sign of movement as it took notice of the difference in the amount of space around it.
As the box vanished, it continued to remain still for a bit. Its roots then began to slither with a hint of hidden vigor. And as its roots began to slither, the bottommost head turned itself directly at the students' direction.
Then the head above it turned to the students' direction. Then the other moved, and all but the topmost head began to clap their mouths angrily, threatening to lash out at the students as they moved with a rather unpredictable movement.
Slowly, the Grimm's primary head looked down at the students.
At the Dionaea's movement, Port, excited to see the students take down the Riesen-class Grimm, boomed,
"Begin!"
As soon as he yelled, the Dionaea's smaller heads screeched loudly at a high pitch as the largest head simply watched the students. Its many tendrils soared, each of them moving with impressive speed towards each and every student as the Grimm itself backed away from the students. About two roots were flown at each and every student, and even then, it still had unused tendrils at its disposal, which seemed to defend the Grimm from anyone who approached it immediately. The tendrils that were sent to the students were either set to smash them aside sideways or knock them up in the air.
If one were to immediately go for cutting the tendrils, they would find out that the limbs were sturdy despite their flexibility. And the Grimm's sheer weight prevented it from being forcibly moved by simply attempting to grab it by its roots. Repeated attacks or heavy attacks would be needed to think about cutting them down, and that meant that being left open was a certain possibility. Whenever its tendrils missed or was smashed away from the students, they quickly went back to attacking without rest.

As the battle started, Sangue immediately stood behind Ben with her hand at the handle of her blade. The sudden onslaught of the Grimm's limbs that was sent towards the students' way caught her off-guard, but she didn’t expect it to be on the same level as the lower-class Megaladeus she had faced before.
While she had separated from Ben in that particular class session, she intended not to stay too far away from him this time. He did give her the direct command to stay behind him, after all.
Eying the tendrils that shot towards her, her gaze sharpened as her somewhat intimidating glare returned. Her grip tightening as she drew her blade, the redhead flipped over a root that swept itself underneath her feet before slashing upward at the other limb that shot towards her. Much to her surprise, the Plant-type Grimm’s limb was barely cut, having only a small scratch on the surface of the limb, and bounced up from her before returning to the stem. When one of its roots returned to attack her, she decided to slip past the attack with a sidestep as she moved directly behind Ben.
"..."She remained silent as she kept her guard on full alert.
