They silently but quickly glanced behind them to see a warrior holding a longsword with twigs caught in his hair, and a mage with several cowlicks covered with leaves, running towards them.  

"Heeeeeey!!! Run away!!! Away!!!" the warrior warned, waving his arms up in the air.  

"Call the teachers!!!" the mage shouted to them.

They suddenly felt a shadow covering them, they looked upwards to see a tall monster.

It was a giant flower with a mouth at the center filled with sharp teeth and four fangs bulging out, and there were blue patterns flowing through its violet petals, framing it. The stem holding the creature was long, filled with unpatterned blue thorns and seemed to have multiple layers to be at that kind of size.

The forest cleared away as the strange sound kept getting closer, there was a huge thud from what seems to be the steps of the monster.

Reaching out of the forest, the stem was connected to the head of a green creature, scaly looking with big pitch-black eyes occupying quarter of its head, it has a crocodile shaped nails and legs, and a mouth reaching half of its head that seemed to be painted with a blue smirk. It's forehead had three small horns while there are two at the side of its presumed chin, and on its body were four vines with horns at its end.

"Bad news..." Atia catched her breathe, she suddenly felt herself getting lifted and her abdomen placed under somebody's arm.

"LET'S RUUUUUUUUUUUN!!!" Torin screamed as he quickly run towards the express carrying his two party members on his sides, hoping to run fast enough for the three of them to survive.

"H-hey, don't forget us!!!" the mage screamed from behind.

"Idiot, keep running!!!" the warrior yelled at her.

From their back was the creature opening its wide mouth, showing multiple layers of sharp teeth

Ilich was wiping his gun with his handkerchief, as he deeply cleaned the metal part, it reflected a tall figure running with dust following its trail. He raised his head to find a bruiser running directly to their express, there were two adventurers under his arms, one who appears to be a scholar, and the other was pretty familiar... --Atia?
'What is going on?' he thought as he stood from his seat, there, with his keen eyes, noticed a purple gigantic figure from afar.

As the moment he notices it, was the moment others came to notice it as well.

"What is going on?" a hydromancer stepped outside, shading her eyes with her hand.

"Hey, I recognize that bruiser!" the thief followed the hydromancer outside, "Ehy! Torin! Buddy--what is--"

Before he could continue his question, the scholar yelled at the students, "Where is Miss Guilimiere, or Sir Theodore or any teachers?!!!"

"Huh?" They all sound confused.

Just then, something from above the express leaped with a high speed pass the three fleeing students, leaving a flaming tail within the atmosphere.

Reaching the express, Torin dropped the girls on the grass as he catch his breathe, kneeling in exhaustion.

"T-thanks Torin..." Atia thanked, "That aside, what was that? The flaming thing..." Atia asked as she looked at Emily, the two of them shared confused looks.

The thief rubbed the back of Torin as he gave him a glass of water. Other students went outside to view the situation on the field, where the flaming tail had trailed into.

As the mage fall onto her nose, the warrior stopped from his tracks, turning to find his friend about to be eaten by a beast.
Time flows slowly...

Just then, a heat traveled overhead of them and in a blink, they saw the familiar yellow ocher hair-- it was Guilimiere Leoplay, breaking the middle horn on the monster's forehead with her fist digging into its head.

"M-miss-- Miss Guilimiere..." the warrior fell on to his bottom, surprised by the appearance of their teacher.

Guilimiere then forced her flaming fist, burying deep into the monster's presumed skull, making it cry in pain.
The creature immediately used its vines to attack the teacher to only find all four, held by Guilimiere's fist, clenching it-- she tore it into half, making the creature's suffering, double.

It's petal then started to move, trying to swallow Guilimiere, but suddenly stopped from moving, and it seemed to tremble instead. Green juices  flowed down onto its forehead as the petal fell on to the side, cut from the stem and quivering.

Guilimiere pulled her buried fist, and gave a final blow into its wound. Burning the beast internally as its body slowly disintegrated from behind, along with its separated body parts.
She then went down from the beast and glared at the two students on the ground.

"Let this be the lesson for all of you, young adventurers..." Julius stood before the C Class students inside their dorm, with the mage and the warrior standing before them, beside the principal. "Ymir, Robyn... Not only you have entered the forest, but you also have put others into danger! I hope you won't do this again, understood?"

"Yes principal..." the two students answered, still facing the floor.

"Now, you will spend your time in detention, follow me..." the principal said as they left the dorm.

All the students stared at them as their back disappeared to the hall. The room then broke into murmurs as several students left the dorm.

"What will happen to them?"

"They have taken this exam too seriously, this might cause a lot of troubles..."

"C Class A sure had a lot of troublemakers... they might end last at the end of the year..."

"I wonder if this would be a competition"

And several inaudible murmurs echoed through the room until the only ones left were a few students, standing in silence.

"They might be at fault for their detention..." the hydromancer sighed as she held a paper in her hands, looking at it with a mix of disappointment, "...the whole section was affected by rank..."

"They have brought a lot of crystas and with their detention, the teachers did not considered the collection hence subtracting the amount they collected from ours in account..." a berserker gave a sigh.

"Anyways, who are you guys?" Mica asked, hopping forward for everyone to see her.

"T-that's pretty rude for a salvager!" the hydromancer complained, "I have been sitting next to you in class, it's Eren!!"

"Is that so? Oh sorry about that!" Mica scratched her head.

"I'm a good thief so don't be that wary against me, miss salvager!" the thief laughed.

"And who might you be?"

"I'm Willem!!" the thief beamed a smile as his cat ears tweaked.

"Whoa! Are those ears even real?"

"They are! They are!"

"It's getting lively in here..." the berserker shrugged, Atia and Eren, who were near him, looked at him.

"And you are...?" Atia asked, leaning forward to be recognised.

"Austin..." he simply answered.

"Tight-lipped person huh..." Eren said as she open a finger as if counting.

Atia then heard some footsteps, based on its pace, they are running. A familiar voice then echoed through the hallway, as if yelling: "Petra! Take back what you have said!!!"

She turned to the door to find Emily chasing the dancer into the dorm throwing her fist, midair. The dancer laughed as she jumped onto a second bed from the girls column. "I won't, until you admitted it~!" she smiled playfully, "Just admit that--"

"It's not even real! Never! Nada! Nu-uh!!" Emily cut her mid-sentence, pointing her finger to Petra with a red face.

"Then I won't take it back~..."

"Why you?!"

"Ehmz, Petz-- don't fight~..." the sage stepped forward as she gestured for Emily to cooldown.

"I won't, Lillian! Until that egoist or bully won't stop bugging me about that matter!!" Emily pointed at the laughing dancer, accusingly.

"It's pretty lively here, right~!!" they all turned to the door to find the bard waving at them in a friendly manner.

"Oh my..." Petra mumbled as Emily dashed her way towards the bard.

"I'll kill you if you say another word..." Emily threatened the bard as she pulls his collar, "...Despite being a scholar I know where I can one-stab kill a person..."

"Oh my... how scary~!" the bard laughed.

"Can you twins pipe down? Petra, Peter, you're obviously disturbing Ehmz..." the monk crosses his arms as he enters the room.

"Well, you should know that smaller girls are fun to tease, Hugh!" Peter gave an amused laugh, although Emily ignored his words, from afar Atia's heart was stabbed by a knife-- falling to the floor on her side, coiling herself in a fetal position.

"A-are you alright, Atia?!" Eren asked as she touched Atia by her elbow.

"It's good to be tall right...? As tall as the ceiling that you can't even enter the room..." Atia mumbled to herself.

"See?" Peter laughed again.

"Everyone! I have suggestion to check on Ymir and Robyn!! How about it?" the striker bursted as he run inside waving his arms in the air, "Serene had already agreed, how about you guys?"

"Although it was Juno who suggested in the first place..." the archer scratched her cheek sheepishly. "What happened here anyway?"

Serene looks at her classmates who are all gathered up, all their stares locked at the two with frozen expression.

"Do you find it coincidence that all the Class C-A students gathered inside the dorm?" Petallite asked turning to Ilich beside her.

"It's already planned, I guess.." Ilich answered as he looks around in confusion.

"HEY, DON'T FORGET ME!!!" someone exclaimed from the above then it leaped down, it was the pyromancer Atia saw earlier.

"And who might you be?~" Mica and Petallite asked in-sync.

"You asked me to enflame the potion you threw, and you were the one who watched my fire-play closely ago!!!" the pyromancer pointed angrily at the two innocent-looking adventurers.

"That's why, who are you?" Mica and Petallite asked in-sync again with blank expression.

"Hey, hey! Be nice!" Torin gestured.

"I'M ELDAS!!!" the pyromancer shouted, panting from all his overactions.

Inside the detention room, that what looks like a to be a prison-holding cell, on the chairs sat two students facing the window, looking gauntly.

"So...?" Ymir breathed, feeling lifeless.

"What are you guys doing here?..." Robyn continued.

Out of the window gathered all the Class C-A students, smiling and waving at them in a friendly manner.
