Crossover Anime: Offering Myself as a Sacrifice to the Sword? I Choose to Be the Great Demon King

Lai Chan High School, rooftop.

Kurumi glanced at the playground not far away, then changed into her spirit dress, lightly touched her lips with her finger, and said:

"Oh dear, it's almost time, Shiori-san!"

The sunlight shone on Kurumi, casting a shadow on the ground.

Kurumi lightly tapped the ground with her toes, and her shadow instantly began to expand, spreading outwards from Kurumi herself towards the school, quickly engulfing the entire rooftop.

As time went by, the school buildings, activity rooms, and classrooms were all covered by shadows.

Soon, the entire school and even some streets were enveloped by Kurumi's Time-Eclipse Castle Barrier, making it appear to those inside the school as if the sky had suddenly turned dark.

"Shiori, let me test whether you're being sincere!"

In class, the teacher was still tirelessly lecturing, completely unaware of the changes outside.

Mo Li raised his head and looked out at the dark sky and the immense spiritual energy in the air. It seemed that Kurumi had already made her move, so he had to make some preparations as well.

The teacher, who was giving a lecture, suddenly collapsed to the ground. As the other students were about to go to check on him, they too began to faint one after another.

Of the entire class, only Mo Li and Itsuka Shiori remained unfazed.

"What... what exactly is going on, Mo Li?"

"Don't you already know the answer in your heart? Why bother asking me? Isn't this fine? At least there are some things they'd rather not know!"

"As expected, it's Kurumi. I know now, I will definitely save her!"

Upon hearing this, Mo Li raised an eyebrow, noticed a deathly aura emanating from Shiori, and shook his head.

In order to prevent her from dying as soon as she went up, Mo Li stood up and explained:

"Here's a piece of advice: don't make promises to others without being sure you're sure."

"Hey, what does this mean, Mo Li?"

"Figure it out for yourself. Remember, if you want to gain Kurumi's approval, you have to be prepared to die."

After saying that, Mo Li turned around and disappeared, leaving only one sentence in the air:

"Don't try to ask me for help. No one will come to your rescue this time. Good luck to you!"

Shiori was stunned for a moment after hearing Mo Li's words. She tried to contact Ratatosk through her earpiece, but there was no sound from the other end. What Mo Li said was true.

Even so, Shiori refused to give up. After taking a few deep breaths, she headed towards the rooftop.

Meanwhile, Kotori, who was confronting Mana, also received a message from the school.

Given the urgency of the situation, Qinli didn't offer much explanation, nor did she mention the agreement between her and Moli.

The most important thing now is to get in touch with Shiori; Kurumi is no ordinary spirit.

At the same time, Mana also received a message from AST and left the venue immediately.

"How is it? Are you able to contact Shiori?"

"No, the signal is being jammed, I can't see what's going on inside, ahhhhhh..."

"What's wrong? Hey, talk to me, what happened?"

Kotori heard a scream coming from the other end of the earpiece and immediately sensed something was wrong, so she quickly called out repeatedly.

But no matter how Kotori called out, there was no response from the other side.

After a long while, a series of intermittent sounds were heard, and the sound was believed to be Murasame Reine.

"Kotori, Fraxinus has been attacked and is unable to communicate with the outside world. We can't help you anymore."

"Who is the enemy? And what about the random domain? Why hasn't it been deployed?"

"The enemy is... Yoshino!"

"What did you say? How is that possible? Damn it, it's that bastard Mo Li's doing again!"

Kotori instantly understood the whole story; it seemed that guy was determined to protect Tokisaki Kurumi.

Since that's the case, even if I'm the only one left, I still have to help my sister seal away Kurumi.

Thinking of this, Kotori quickly ran towards the school. Shiori, without any support, was likely in danger. That guy Mo Li, she really couldn't trust him.

Fraxinus, Command Room.

The entire warship was covered by a layer of ice and snow. Apart from the propulsion system, which was barely functioning, all other weapons were disabled, and the surrounding area was frozen.

Murasame Reine is also trying to communicate with Yoshino outside, hoping to break the barrier through conversation.

"Yoshino, can you hear me? Can we talk?"

"Absolutely, absolutely we cannot let you interfere with Brother Mo Li."

"We will not harm Mo Li; on the contrary, we will help him!"

"No, Brother Mo Li will release the barrier after he finishes his business, so please don't move around."

Yoshino was determined. This was the first task that Mo Li had given her alone, so she had to complete it, even if it was someone she knew well, like Reine.

Reine hadn't expected Yoshino to be so resolute; it seemed there was no way to communicate with her.

But if a fight breaks out, all the weapon systems will be ineffective. Right now, they are just fish on a chopping board. It's Yoshino who is in this situation; if it were anyone else, they might really be doomed.

Reine can now only place her hopes on Kotori, as Ratatosk is now paralyzed.

Chapter 100: The Battle Begins, Nia vs. Mana

Meanwhile, after receiving the news, Mana Takamiya rushed to the school to find Kurumi.

Looking at the shadow-like barrier, Mana rushed in without the slightest hesitation and made contact with AST.

"Hey, Chonggong, can you hear me? How's the situation over there?"

"This is terrible. I checked, the students just fainted, nothing else is wrong, but..."

"What, are there any other unexpected situations?"

"Tch, you don't even need to think about it to know. If the spatial quake explodes here, the students will be doomed. Nightmare is going to use these people as hostages."

Mana was thinking a lot, and since Shiori wasn't in the class, it meant that her older sister was likely in danger. Mana frowned.

Ryoko Kusakabe on the other end of the phone also ordered people to prepare to leave, but Mana stopped them.

"Captain, I suggest you don't do that!"

"What did you say? Such a major event has happened, how could I not go?"

"This is for your own good. If your actions anger the Nightmare, the students in this school won't be able to come back to life like the Nightmare!"

After hearing Mana's words, Ryo 09 slammed her fist on the table. She had to admit that Mana's statement made some sense.

Liaozi really didn't dare to gamble; there were thousands of lives at the school, and she couldn't afford to gamble with that.

"So, let's leave this to the professionals. Oh, by the way, isn't Origami Tobiichi taking classes at this school? Let her assist me alone."

"I understand. I'll let you know. Contact me anytime if anything happens!"

Mana hung up Ryoko's call. Next, they needed to find the point with the densest spiritual energy. Where was it?

With a leap, Mana jumped directly outside the corridor and was about to run upstairs.

"Sorry, Sister-chan #2, this road is blocked. You should go back to where you came from!"

A calm voice rang out from ahead. Mana looked up and saw a figure dressed in a nun's habit appear in front of her. It was Honjou Nia.

"Sister, with your pathetic abilities, you dare to stop me?"

"Whether I can stop you or not, we'll find out by trying, Beelzebub!"

A pitch-black book appeared in Erya's hands, its pages turning continuously, from which many legendary monsters sprang forth.

At Nia's command, the monsters charged toward Mana.

Facing the monster with its gaping maw, Mana was not alarmed. She swung her lightsaber a few times in the air and cleaved the monster in two before it disappeared into the sky.

After doing all that, Zhenna gave Erya a provocative look, as if to say, "That's all there is to it."

Seeing this, Niya was not angry. More magical beasts appeared and rushed towards Mana all at once.

The increase in numbers didn't cause Mana much trouble. She simply nimbly maneuvered in the air, aiming her laser cannon at Nia and firing it at her with a bang.

Erya originally intended to have the monsters intercept it, but who would have thought that the laser beam would twist and turn, heading straight for Erya.

Just as the laser was about to hit Nia, the Divine Eclipse suddenly appeared in front of her, enveloping the incoming laser and averting the crisis. However, this left Nia somewhat shaken.

At the same time, Mana also discovered the weakness hidden behind Nia and mocked:

"I see. I don't have any real combat ability; I rely entirely on the summoned monsters to keep up appearances."

"Hmph, if you're so capable, then charge over my treasures!"

"Since you've put it that way, then I'll grant your wish."

Mana was prepared for this. She casually cut down several charging monsters, then flew into the air, holding a lightsaber, and sped towards Nia.

Little did they know that Nia had been waiting for Mana to arrive, a smile playing on her lips.

Just as Mana rushed in front of Nia and raised his lightsaber to strike, the Divine Eclipse suddenly grew larger, enveloping Mana completely and making him disappear.

"The Book of Divine Eclipse - The Illusionary Library (Ashufiriya), humph, this is the price you pay for underestimating me!"

The Illusionary Library is an advanced ability within the God-Eater's Tome, possessing the power to imprison people in any story. Those imprisoned will be trapped in a small space similar to a neighboring dimension.

Those imprisoned in the story will become characters in that story and will be unable to use any power. The only way to escape is for the user to reopen the passage or to open the passage with the help of the powerful power of the characters in the story.

Niya snorted coldly. In order to get revenge, she specially set the Ragnarok story at a hellish difficulty level for Mana.

Basically, it takes several years for someone to truly get over it.

In the corridor of another school building, Origami was struggling to keep herself from collapsing.

Because of the City of Eclipse, Origami also had some time absorbed. If it weren't for Mo Li's training last time, she probably would have fainted on the ground like the other students.

Origami laboriously pulled the temporary display device out of her pocket, placed it in her palm, and pressed her fingers on it.

"Identification: AST Tobiichi Origami!"

The chip unfolded instantly, and after confirming that the fingerprint was correct, the words "Recognition Completed (4)" appeared on the chip.

"Basic display device - activation certification!"

After Origami finished speaking, she gently placed the device on the receiver on her head. A flash of green light appeared, and Origami's school uniform instantly transformed into the combat suit of the display device.

After the Free Domain was activated, the weakness caused by the City of Eclipse was greatly reduced, and I was able to move around.

Origami stood up, looked around, and breathed a sigh of relief after confirming that the teachers and students were only unconscious.

Pushing open the classroom door, Origami ran swiftly down the corridor.

Suddenly, the voice of Captain Ryoko Kusakabe came through the headphones.

"Yuan Yi, you dressed in a hurry, right? How's the situation?"

"Extremely dangerous! The school is covered by an unknown barrier. Requesting backup!"

"I'm sorry, Tobiichi, I can't offer you any help here. I need you to immediately join Takamiya to form a special operations team and investigate this incident!"

"Yes, I understand. I'll go find Mana now."

Origami stopped in her tracks, then suddenly remembered something and quickly ran towards her class.

As expected, neither Mo Li nor Shi Zhi were there, which meant it was another nightmare.

"Captain, where is Takamiya now? Also, could you please help me investigate the source of the spirit wave?"

"The last communication with Chonggong was in the second teaching building. I don't know what happened there, and we can't get in touch with him now. As for the source of the spiritual wave, it's on the rooftop, on the school's rooftop."

"Please help me confirm, besides Nightmare, is there anyone else here?"

"No, the image cannot be uploaded or confirmed!"

Liaozi's voice was intermittent, which made Origami frown; there must be a problem with the signal transmission.

Now Origami has two options: one is to go to the second teaching building to meet up with Takamiya Mana, and the other is to go to the school rooftop, since Shiori will most likely be there.

After much deliberation, Origami still headed towards the rooftop, reasoning that with such high strength, Mana would surely be alright.

Clearly, Shiori's safety is still a top priority for Origami, especially with the unpredictable factor of Mo Li lurking in the shadows, making it impossible for Origami to be certain of Mo Li's attitude.

Just as Origami was about to head to the rooftop, a purple figure appeared in front of her, blocking her way.
