Invicinble Colorless Butler

The Magic Train of Piqmentia Grand Academy that took students to the Alba Mountain Range is currently being surrounded by thousands of monsters. The teachers, principal, and King Leonida fought against the monsters. The teachers looked overwhelmed against the endless wyverns. Kalya who was currently surrounded by dozens of wyverns inadvertently lowered her guard. As a result, she belatedly realized the two-way attack coming at her.

(Be careful!)

Upon hearing Silphy's scream, Kalya immediately created a double-sided barrier for each attack. But unfortunately, the strength of one of the barriers wasn't enough to withstand the wyvern's attack. The fireball headed straight for her, Kalya no longer had time to dodge or create new barriers.

"Miss Kalya!"

There were screams from her fellow teachers. The one who switched classes with her, Ashley Arianel. When she was ready to clash head-on with that fireball.. Kalya suddenly hears the voice of the man she loves.

(You're careless, Leya)

Kalya's heart calmed down after hearing Ziel's voice. Her panicked face was replaced with a smile like a blooming flower. The ring on her finger gave off a gray glow.

[Aegis Fortress]

Boooooooommmmmm

The fireball was restrained by a fortress-shaped gray barrier with a human face pattern in front of it. When the wyvern realized that his attack had no effect. Dozens of other wyverns shot fireballs simultaneously.

Boooooooommmmmm

No matter how many times the wyvern shot fireballs, the barrier was not scratched in the slightest.

"What's that?" Ashley who was near Kalya was surprised to see which fortress suddenly formed protecting Kalya.

"Artifact, not to mention the rank is very high. Where did she get it from." Merlick who was fighting the green dragon narrowed his eyes at the gray fortress.

Kalya was also dumbfounded by the defense of the ring given by Ziel, even though he had told it directly but when she saw it with her own eyes, she was very surprised to see that dozens of wyvern fireballs had no effect at all. At least the combined attacks were enough to injure a demigod.

"I'm sorry, Ziel." Kalya feels guilty for making him worry about her, but on the other hand, she feels very happy. She could feel warmth welling up in her heart.

(You don't need to apologize. You'd better beat the wyverns right away)

Ziel knew that the longer they fought, the more they were at a disadvantage.

"Eh? But how? They seem to keep popping up." Kalya also wants to finish the fight immediately. But she didn't know how to deal with endless enemies.

(Leya, listen carefully. Everything you do is like a cycle. When 100 wyverns die, they will reappear within a certain time. It seems to be a skill of the green dragon. So if you want to stop the cycle, You can choose between killing the green dragon or killing all the wyverns within a certain time without letting them reappear. You only have 10 minutes to wipe out all the wyverns)

Ziel gave a detailed explanation of how to defeat the monsters to Kalya.

"If we only focus on the green dragon then the wyverns will interfere and maybe even attack the Magical Train, but if we choose to kill all the wyverns within 10 minutes, that sounds a bit impossible." Kalya feels helpless at this point. Because of the two choices that Ziel did, neither of them was easy to do.

(Use your ring)

Ziel gave her a short answer.

"This ring? Doesn't this ring only have a defensive function?" Kalya saw the object attached to her ring finger.

(That's just one of them, while the barrier will automatically activate if the user is in danger, for attack mode you have to inject your mana to activate it)

"Okay, I'll give it a try. Thanks, Ziel." She felt she could do it as long as Ziel said so.

(Yes, please be more careful)

Ziel finished his telepathy to Kalya.

(Have you finished talking to your lover? What was he talking about with you that temporarily blocked our connection?)

Silphy's teasing voice suddenly sounded in her mind.

"It is nothing. Putting that aside, right now we must kill all those monsters at once." Kalya spoke with a tone full of confidence.

(Hee... Just talking to him for a while can make you like this. I'm getting envious. Hehe...)

Silphy who saw Kalya's face full of determination tried to tease her again.

"Noisy. Let's defeat them immediately." Kalya immediately injects her mana into the ring. Suddenly thick gray mana came out of it. Mana continued to pour out until it filled the sky above her.

(Uh, what is this? I feel something dangerous coming out)

Silphy was shocked to see the thick gray mana pool in front of her.

"I don't know, he just asked me to put mana into it." Kalya shook her head at Silphy's question and continued to look at the phenomenon in front of her.

The thick gray mana condensed and formed something. A creature hundreds of meters long, with horns on both sides of its head, and extremely sharp claws on its feet. His entire body was covered in scales, and the scariest thing was his red eyes.

[Seiryu]

Roooooaaaaaaaaaaaaarrrrrrrrr...

A dragon's roar echoed throughout the battlefield.

***

Inside the Magic Train, the students watched the battle between their homeroom teacher and the wyvern. They can also see the fight between the green dragon against the principal and King Leonida.

"Look! Our academy teachers are truly amazing. With one hit they can kill dozens of wyverns!" One of the students from class D screamed hysterically.

"You're right, our homeroom teacher isn't inferior to the other teachers either. Her wind element is simply extraordinary." The other students also responded.

"Hey, why do you look uninterested in the fight?" Rhea asked Ziel who was supporting his chin with his hand while closing his eyes.

"No, I'm just sleepy. You don't have to worry about me. You can continue watching the fight." Ziel answered without opening his eyes.

"You... whatever! Oh, look! Miss Kalya is surrounded by wyvern!" Rhea screamed in panic seeing Kalya being attacked by dozens of wyverns.

"Eh?" Not long after, she was shocked after seeing what was happening before her eyes.

***

In the class S carriage, the students were enthusiastic to see the fight between the green dragon against King Leonida and Merlick. They fought fiercely. The green dragon is seen several times receiving slashes from King Leonida's Claimh Solais and magic attacks from Merlick. Even though he wasn't seriously injured.

"Look at the homeroom teacher of class D! She was hit by a wyvern!" A class S student pointed at Kalya which was being attacked by the wyverns from two directions. Kalya who has a beautiful face is not only famous in class D, but also throughout the academy.

Princess Aishia and Princess Freya who saw King Leonida's fight suddenly turned their heads and looked at Kalya. After the smoke from the fireball attack dissipated, Princess Aishia trembled at the sight in front of her.

"Isn't that... Ziel?" Princess Aishia muttered in a low voice. She was familiar with the gray mana, though she wasn't quite sure right now. Princess Freya who was beside her could hear what she was muttering. She clicked her tongue when she saw Princess Aishia's expression.

"What's that!?" One of the class S students shouted seeing the huge gray fortress protecting Kalya. Even the fireballs from dozens of wyverns couldn't scratch it.

"As I thought, what she has is amazing." Princess Rinne muttered looking at the fortress that was forming in front of her.

"Is it an artifact? How high is it rank?" The curious Princess Reina asked her.

"Unfortunately I don't know. I wish I could directly hold it." Princess Rinne shook her head looking disappointed.

"It's a god-rank artifact. I didn't see it at first, I didn't expect an academy teacher to have something like that." Suddenly a voice came from behind them. He is the father of Princess Rinne, Raghnall Cirlus.

"Dad, what are you doing here?" Princess Rinne was confused by her father's sudden arrival.

"I was asked to take care of you, so I will check every carriage." King Raghnall answered half truthfully. He was just bored sitting there alone.

"What the hell is that!?" A student from class S shouted and made everyone in the carriage look at what he was pointing at.

The fortress that previously protected Kalya disappeared, and thick gray mana suddenly burst out of the ring and gathered above her. Little by little the mana condensed and formed a creature that was even longer than the Magic Train they were currently riding.

Roooooaaaaaaaaaaaaarrrrrrrrr...

This was the third time he had materialized in this world.

"Ziel, it is him!" Princess Aishia involuntarily shed tears, she was determined to meet the teacher after the problem was over.

The princesses are not aware of Princess Aishia's condition except for the person sitting next to her, Princess Freya. She felt that this would be troublesome in the future, and can only sigh heavily in her heart.

"What's that?" King Leonida was surprised to see Seiryu who suddenly appeared. The attention of everyone on the battlefield was fixed on the huge creature.

Suddenly Seiryu started to move and wagged its tail at the horde of wyverns. Its tail was as big as a wyvern's body that could cause instant death if hit by a swing.

He didn't stop there. He flew towards a nearby wyvern and started a rampage. He bit it with his fangs and clawed it until it became minced meat. Seiryu then looked at the place where the wyverns gathered the most. He opened his mouth and the lightning began to gather into a dense mass of energy.

"Everyone get out of there." Kalya who sensed the danger of the attack immediately alerted the other teachers. Those who heard Kalya's warning immediately fled from there.

[Dragon Breath]

Seiryu shoots a laser beam of compressed red lightning. All the wyverns in the attack trajectory vanished into nothingness. Seiryu changed the direction of his attack towards the other wyverns until not a single wyvern remained.

The other teachers were even dumbfounded to see hundreds of wyverns vanish in less than 5 minutes.

"Miss Kalya, what is it?" Flavio woke up earlier from his shock and asked Kalya.

"Hmm... Let's just say he's our helper." Kalya who is also surprised to see Seiryu's strength is confused about how to answer it.

"I didn't know you had such a great creature." Reid joined in on their conversation.

"We'd better discuss that next time, right now we have to help King Leonida and the Principal who looks desperate." Beatrix cut off their conversation. All the teachers nodded in agreement and charged forward to attack the green dragon.

For a one-on-one battle, Seiryu in the Kalya ring might be evenly matched against the green dragon. But if she chose to fight him first, the wyverns would keep re-emerging while the green dragon still hadn't been defeated. Other people couldn't interfere in a demigod class battle. They will only be a burden. That's why Ziel asked Kalya to eradicate the wyvern hordes first because Seiryu would win against them rather than just a draw against the green dragon.

After Seiryu had finished his task, he turns into a light particle and reenters the ring on Kayla's finger, and the second half of their battle began.
