Let's roll back the time where the company has divorced Elena from Araki. The head of the student council held a meeting that afternoon, where the others got there on time. Council members are the following: Chris Westland, Shinoji Ryuga and Jessica Scharz.

They listened to Elena's report in shock. By the end, nobody dared to speak for a minute. Chris broke the silence.
"I don't even know what's harder strike to stomach? Is it that Alto and Vermeil defeated the scumbag who attacked the Academy during the exam period, or..."
"...Is that this double can wipe the floor with us at any time in the present moment." Jessica ended her sentence.
"Anyway, we can be happy to be on our side. otherwise mankind has no chance." Shinoji sighed.
"Let's not go into what if scenarios." Elena interrupted further reflection. "Let's focus more on ensuring that the students are not further harmed or possessed. Shinoji! Did you grant my request?"
"Yes. At the moment, I received the data of all staff, students and director of the Academy. After a thorough inspection, I can say for the time being that there are no traitor between us."
"I'm glad to hear this." Elena said and wrote down. "What about Obsidian?"
"Wasn't he supposed to be dead?" Chis asked.
"Unfortunately, no. He's gone, and all that's left is a severed arm. His injections were found, hidden in a storage room behind a bookcase. Upon closer inspection, we discovered that it contained the blood of a legendary demon named Odio."
"That's Impossible! Odio died centuries ago!" Jessica shout.
"We thought so, but it proves that he or she was alive. There is no other explanation for why they were attacked at the Bronze Range Exam. They wanted to catch Vermeil." Ryoshi answered factually.
"Yes. What does this Blood do?" Elena asked.
"Odio's blood completely infects the mind and provokes a feeling of hatred and just wants to destroy. Those who have no or very little will only be killed slowly."
"This explains of Rex's and Vermeil's rampage."
"Well, it worked for the latter because demons are easier to infect with this blood than humans."
"That's it! I'm gonna kill all of Platinum cesspool!" Chris shouted with full rage. "If I see one, I'm going to hit them as long as there's life in them!"
"That's enough." Elena raised her hand. "Rage does not help anything. Right now, the most important thing is to handle the situation as calmly as possible."
"True. I'm sorry."
"I understand you're rage. Since Rex was infected, you've been looking for them ever since. Other report?"
"None." said all of them.
"Then I adjourn the meeting."

Late that afternoon, Elena and Jessica had a sword fight. This was their joint training, which has become a routine since they joined the student council. Elena noticed that Jessica was quite preoccupied with her thoughts, as she knocked the sword out of her hand with playful ease.
"Something's bothering you, I see. Did you eat your protein bar?"
"I'm a little afraid of him. I read that in larger quantities it causes infertility."
"If you go on like this, you will be never a true Jedi, my young Pedovan." Elena laugh after her sentence. "Seriously, though. Are you having concerns about Vermeil again?"
"The hell I don't! She's a demon who always has in mind the subjugation of humanity."
"Jessica! Vermeil has only subjugated Alto' heart so far, but it was only good for him."
"But our enemy is also a demon! Plus, a demon who died theoretically for centuries!"
"Then it's good that one of the most powerful demons has become a human familiar. Alto enjoys my full trust, as does Vermeil."
"How can you trust them so unconditionally? What if they betrays us one day?"
"They're too good-hearted to do this. In addition, Alto wants to achieve world peace."
"Wold Peace?" Jessica laughed. "He must be a real idiot, that's for sure. I'm not going to make peace with demons."
"Think as you want. I'm going to take a bath." Elena closed the debate. But she suspected Jessica didn't want to stop, so she turned around. "Anyway, before you come with anything, think a little about the situation a bit. Obsidian is human, Iolite was a human and Platinum Ranks maybe humans. There is only one demon on the enemy side, as here too."
Elena finished her sentence. Jessica looked at her only puzzled. Maybe she's right?

The next day, everything went in the usual riverbed at first sight. Chris and Shinoji were just training when they suddenly felt something weird manna.
"Did you feel that?"
"Yes. Someone has entered the territory of the Academy. She... is here!"
They looked back and looked at a young, beautiful woman with an icy aura. Her brown hair was blown by the wind, and a cold sense of purpose emanated from her eyes. On the side rested an ornate sword.
"Who are you and what are you looking for in the Academy, where unauthorized people can't put their feet?" Shinoji asked with suspicios tone.
"I beg your pardon. My name is Oersted Amira. I'm looking for someone right now."
"And why here?"
She didn't answer that question. She rolled her eyes around and then spoke. Her voice was unabashedly cold, as if steel was in the place of her vocal cords.
"Where are Alto and Vermeil?"
"You don't have to say anything!" Chris cried, whose voice was shaking the anger. "You belong to the platinum filth!"
"There's no other options." Shinoji sighed, that his tone change with cold tone. "It is better to give up yourself or we will be forcibly brought in front of Magic Police."
"It is unnecessary to use violence. If you reply, I leave voluntarily."
"You don't seem to understand the seriousness of the situation, bitch! Either you come with us in a piece...or in pieces! I summon you, BLACK DRAGON!"
"I summon you, FENRIR!"
Both of their familiar seal flashed. A huge black dragon flew up on Chris's side and she jumped over. Next to Ryoshi was a huge white fur, red -eyed wolf standing. Oersted only watched them a cold stare.
"I'll admit you're doing a good job. But, if I have to attack, there will be no thanks to you."
"Then load up, bitch! Let's get started!"
At Chris, Ryoshi and Fenrir trampled on the ground at the same time. It had no effect on the opponent at first, but she flied up, just right on the face of Chris's dragon. It blew a huge blaze that would cremate a man in a matter of seconds. At first, it worked because nothing fell on the ground. Chris laughed.
"That was your best, filth? In the high areas I am the Empress!"
But then they were shocked by Oersted's response. She was even higher than the Dragon.
"Really? Then defend this."
Her hands looked like she was doing magic and began to fall red and black flower petals.
"What the?" Ryoshi asked while preparing for the defence with his familiar.
"Fall from the sky... exploding flower petals!"
Chris and her dragon fire them and blow them up. This could have been good, only more petals fell than exploded. They got the explosions in line, but Ryoshi and Fenrir also got them down there. By the time the magic ended, they were both lying on the ground with injuries. The only fortune is that they both recalled their familiar.
"That's why I said it was superfluous for violence. So... Where are Alto and Vermeil?"
"Eat shit and die." Chris moaning.
"If we could, we wouldn't tell you." Ryoshi replied.
"I see. You're telling the truth. Where are your friends?"

Then Jessica wanted to stab Oersted, but she dodged under a fraction of a second.
"Well, another human? Interesting. At least I don't have to look for you as you come on a conveyor belt."
"What are you doing here, demon?"
"She's a demon?" Ryoshi and Chris asked at the same time.
"Yes. As much as she tries to cover her Manna, she couldn't deny it."
Oersted smiled, which made everyone's hair stand up. The horns on her head grew, and her tail was also visible, which it rested on the sheath of her sword.
"You're pretty good. In return, answer me a question. Where are Alto and Vermeil?"
"I don't know, but I can tell you one thing. If she wasn't protected, I'd be the first person to kill Vermeil. Demons are a despicable, filthy, cowardly bunch who seek the life of humanity. For thousands of years, you wanted to subdue humanity and swore to my father's name that all demons you've written out of the earth!"
"I'm sorry, were you just talking about the human kind?" Oersted asked back, with some anger in her voice.
"This is the truth about you! You are the Earth's pleauge without whom this whole world would be better."
"You're wrong! Humans are no different than us. All cowardly, two-faced, disgusting, primitive worms. Every single war was started by humans, you brought species to the brink of extinction simply because of raw material, god complex or entertainment. Which demon just wanted to live a peaceful life, you slaughtered its entire family. When a demon take revenge or kill for self -defense, you cried after you only acted in the name of truth. In fact, you are only experiencing your lowest human instincts. Like you did with Atlantis... or Vermeil... or me."
"That's a lie! All you ever did was kill! So take out your sword and I'll wipe you down for good, demon!"
Oersted laughed at Jessica that awakened the fear in everyone. It's was a malicious and maniac laugh.
"You seem to be pushing only the propaganda of humans. True, since you have already considered Vermeil as described from the beginning. The only cure for your blindness is death. Besides, I don't need a sword to deal with you. In fact... You have such pathetic power that I don't even have to resort to magic. I'll just use my bare hand."
Jessica couldn't stand her nerves and attacked almost in the blink of an eye. It was actually intended to kill. Oersted, on the other hand, played just that and, after a left dodge, hit her opponent in the stomach. The pain on Jessica's face was visible for everybody.
"Do you feel this? This is honestly feels like." she whispered and pull out her fist.
"Rot in hell, Demon." Jesscia moan.
"Well, I didn't get an answer from you. Then one person left, but I can't see it anywhere. I have only one idea left. I'll kill you, humanity's scumbag. This will be the perfect message to Oritiga, that your race will soon be bites the dust."

Oersted opened her hand and caught Jessica's throat, then slowly strangled her. She felt that she was not breathing because of her squeaky hand. She was about to give up when she suddenly caught her breath again. Opening her eyes, she saw Elena cut off Oersted's arm. Interestingly, the demon woman didn't even flinch. She picked up her hand from the ground and then put it back as relaxed as if it were just a puppet.
"So you're a descendant of the legendary High Priestess Fatema?" she asked the same cold voice.
"I don't like showing this, but yes. My name is Elena. You don't have to introduce you to either... Oersted."
"Good. Then answer my question. Where are Alto and Vermeil?"
"Where are Alto and Vermeil? Where are Alto and Vermeil? Is this the only question you can ask?" Chris moan angrily.
"Yes, and in the same tone. Where are Alto and Vermeil?"
Elena smiled and wiped the blood off her sword with a cloth.
"At least you could lie well. Being a leader, you should be aware that none of them have been here for days. Also, it is superfluous to ask us as we do not know either."
"Clever." Oersted nodded. "Then do you know why I really came?"
"Yeah, but it's too late for that, too. I haven't had a necklace for a long time."
At the end of his statement, he presented the box in which the said object was located and opened it. Oersted was shocked for the first time.
"Where is it? WHERE IS IT?!" She asked with full of anger.
"You know it very well. In the right hands. If they realize how it works then you end up and you will have a real failure of your reward."
"Be cursed, mortal..."
"So you better get the hell out of here, or I'm gonna have to show you the hard way out the Academy."
Oersted was about to reach for her sword, but instead she just put her hand in her arms.
"It doesn't matter who it is anymore. Less than two weeks and there will be no trace of humanity. Looking at you being the best fighters in this pathetic shithole, I don't even need the strength of the two strongest demons. So, if you take an advice from me, give an ultimate prayer towards your gods. But big spoiler... I won't listening."
With this farewell, Oersted has practically dissapeared. Elena helped others to get medical attention.

The next morning, the four began an emergency meeting. Chris and Ryoshi still had traces of the explosion in the form of burns.
"Well, time is tight. So we need to miss an emergency plan if the Platinum Ranks, led by Oerstedd make a final attack on us." Elena started.
"I have an idea. Evacuate the entire academy, at worst, an entire Ortigia in a five -kilometer radius from its center." Chris advised.
"True. I'll give the leaders to the evacuation plan."
"Can students stay fight?" Jessica asked. Everybody see her face, that she didn't sleep last night.
"If they are in silver or gold, then voluntarily. But the bronze and the no ranks are absolutely not. We have little time to train, but everyone who can be mobilized must be mobilized."
"Do we have any idea of the number and position?"
"No, because the information cannot be obtained about them. So it doesn't hurt to prepare for the worst and rejoice in the bad."
"Got it."they answered and then left one by one.

Elena sent a stamped letter in the evening through a pigeon. Although this is already quite old -fashioned but still the safest. She went out into the yard. She then took a deep breath of the slightly cooler air and looked at the sculptural group.
"We are slowly at the door of war. On the chessboard, the pieces are set up. The second war against Odio will begin soon. How strange that you predicted this point by point... High Priestess Fatema."
