Sis-Con with Dimensional Chat Group 833 Intruder

In the audience area.

The big explosion surprised everyone.

"What's happening?"

"Earthquake?"

They knew that a loud explosion wasn't caused by Haru since his weapon was a scythe, not a cannon beam or a bomb which caused them to felt a bit panic.

---

In the monitor room.

"What? What's happening?" Cecilia was confused.

"Haru!"

Ping! Ping! Ping!

The alarm kept sounding through the monitor room telling them that something was happening.

"System damage. Something seems to have pierced the arena shield borders!" Maya reported.

Chifiyu took the commutation device and ordered two of them. "The match is canceled! Kasugano, Fan, retreat at once!"

---

Everyone was in a panic when they realized that it wasn't an earthquake or the result of their fight rather it was an enemy who tried to attack the academy.

The protection mechanism around the arena started to be activated to protect everyone in location, closing the audience's location with a steel shield.

---

Haru and Rin received an announcement from their IS.

'Heat source detected in the center of the stage; confirmed to be from IS of an unknown organization. You're locked.'

"W - What's happening?" Rin was confused.

"It's an enemy," Haru answered her calmly. He looked at her and said, "You should go back first, I'll handle this."

"Ha? Are you telling me that I can't handle this?!" Rin was made once again.

"Alright, Rin-san, I'm too lazy to argue with you, but you don't have much shield energy left right? Your weapon has also been destroyed by me, it is better for you to go back first and I'll handle the retreat until the teachers are coming, alright?" Haru knew that in front of tsundere's character he needed to be patient, but in front of danger, he was too lazy to talk patiently.

Rin looked at Haru for a while but nodded. She knew that Haru was very strong and in this place she would only be a burden for him, especially when she had lost her Impact Cannon.

"Be careful."

But suddenly when Rin was about to move, she was shot by a purple beam.

"Wha---?!"

The purple beam was about to hit her, but Haru appeared in front of her and cleaved down the purple beam destroying it.

"Can you move on your own or do you need me to carry to the dock?" Haru asked while looking at Rin, but he hadn't lost his focus on the unidentified IS since that beam was more powerful than Cecilia's IS which clearly surprised him.

"I - I can handle myself!" Rin snorted at him since this guy kept looking down at her, but when she was about to walk, the IS inside the fire started to move and showed its appearance. It seemed to be moving awkwardly, and it had two large hands and black armor.

Haru raised his eyebrow since he didn't feel life inside this IS.

Usually, it is impossible to pilot an IS without a pilot, and such a thing has never happened in the past.

But it was happening in front of him, he thought the only person in this world who was able to pilot an IS without a person rather using a hacking or remote control.

'Is that person?'

Haru was wondering why that person had done it, but at the same time, he had never seen this IS model before.

"Haruka-kun, Fan-san, get out of the arena right now! The teachers are going to suppress it in their ISes." Maya communicated from the communication device.

"Sensei, this IS doesn't have anyone on it," Haru said.

"What?!"

Everyone who heard it was surprised. They knew very

"Are you sure about Kasugano?" Chifuyu asked.

"Yeah. I'm sure of it, there's no one inside that IS."

"Hmm...." Chifuyu was in deep thinking when she heard it.

"If you can, I can destroy it, what do you think?" Haru asked.

"............."

Chifuyu was silent for a while and asked, "How many percent is your probability to win this battle?"

"99%"

Haru could win against this IS easy.

"You! Don't be so arrogant!" Rin complained.

".........."

Haru raised his eyebrow and asked, "You're still here?"

"Of course! Even if I might not be able to attack the IS, I still can be your support! I'll take care of your back!" Rin felt that it was too shameful for her as an IS Representative to run away in this situation.

"Don't be hot-headed, you should go back," Haru said.

"No!"

Haru decided to ignore her and continued to talk with Chifuyu. "There's still a lot of students who haven't escaped from this place, what is your order Orimura-sensei?"

"..........."

"Why 99%?" Chifuyu asked.

"Because 1% chance, this unidentified IS has the ability to run away," Haru said.

Chifuyu made her decision and took a deep breath. "I'll leave this to you, Kasugano."

"Oh, leave it to me. Now, that you mention it, don't forget about your promise to help me."

"If you can defeat that IS then let's go tomorrow or two days later," Chifuyu said.

"Alright."

---

In the monitor room, Cecilia, Maya, Houki, and Ichika looked at Chifuyu with surprise expressions.

"What?" Chifuyu asked.

"........."

They didn't know what they were talking about, but it was very hard to ask about it when there was an intruder who had attacked the academy.

"Let's just drink a coffee and calm ourselves."

Chifuyu took a cup of coffee and put something inside.

"Sensei, that's salt."

"..............."

Chifuyu blushed at this moment.

---

Haru checked the weapon on his Equalizer.

All IS comes with basic weaponry, called Preset, but it also has a number of expansion slots that could be used to field additional equipment, which comes in various forms, such as additional weaponry, thrusters, and augmented armor plates.

These Equalizers need to be installed into IS first, not an easy feat to accomplish since every IS core is unique and each of them has its individuality, (one might say personality) it is possible for an IS to reject the installation of certain Equalizers.

His Preset is a scythe, but he also had various weapons and support devices inside his IS, though, it wasn't much, but it was very useful.

Then suddenly something appeared on his back similar to an antenna and when it appeared it caused a very annoying noise.

Bzz! Bzz! Bzz!

The camera and some connection to the observation room became very unstable.

---

"What's happening? Hacking?" Maya panicked.

"No. It's a jammer," Chifuyu answered.

"Jammer?!"

"From who?" Maya asked.

Their security was hacked then there was also a jammer which made it impossible for them to call the government for help.

"It's from Kasugano."

"........."

---

Inside a dark room with only a screen of the computer as a light, there was a person who was controlling the unidentified IS, but suddenly the camera of the IS turned weird and caused a lot of annoying noise.

"This....!"

This person smiled and said, "Interesting! Interesting! Interesting!"

---

"W - What is this sound?!" Rin knew that the source of this sound was coming from Haru, but when she was going to ask him. She saw him suddenly had disappeared from her eyes.

"W - Where is he?!"

Rin was surprised and didn't know what had happened.

---

Haru suddenly appeared right behind the unidentified IS and the scythe on his hands suddenly blazed stronger. The energy on his IS kept decreasing at a very fast speed, but he didn't end his attack cleaved the side of the unidentified IS.

Slash!

The unidentified IS was cleaved in half from the side and dropped to the ground.

Haru shook his head and made his scythe disappear summoning a hologram keyboard in front of him. He typed at a very fast speed showing his skill as a hacker and caused the error which happened on the school returned at a very fast speed.

"This is Kasugano Haruka. I've defeated the enemy. Everyone, please calm down and walk slowly without pushing the person in front of you. You're all safe now. Please follow the instructions of the teachers!"

"............."

'Done?'

Everyone was surprised, but when they heard his voice, they started to calm down and walked back slowly since the door which had been locked was also opened.

Haru ended his announcement and flew to Rin who seemed to be stunned. He patted her shoulder and said, "Let's go back."

"........"

Rin nodded dumbly and looked at Haru with complex emotion.

'This guy....'

Rin understood this guy might be the strongest IS pilot out there.
