Comprehensive Manga: The Strongest Demon King Starting from Demon High School

"Then please give me more advice from Mr. Devil in the future!"

"No problem, let’s start the demon turning ritual!"

Roy said with a smile on his lips.

There was no one else present, so Roy started the turning ceremony directly.

"In the name of Roy Lucifergus, I order you, the soul of Butterfly Kanae, to become my familiar devil and be reborn as my soldier!"

The blue magic circle unfolded, and the light enveloped the butterfly Kanae, making it difficult for people to see what was going on inside.

A soldier chess piece slowly integrated into his body.

For a long time, the devil's wings appeared in the light, and then the light dissipated.

It was light. The perfectly preserved butterfly Kanae appeared in the air and slowly fell down.

Masaki and Yadouzi looked at it and blushed. They quickly covered their eyes with their little hands, but peeked through their fingers.

Roy was a little funny, he It was different. He was admiring Butterfly Kanae openly and openly.

When the Butterfly Ninja saw this, he wanted to cover his eyes with his hands. Unfortunately, the Butterfly Ninja, who was only 1.5 meters tall, couldn't reach Roy.

She jumped up and down anxiously. Unfortunately, Roy pressed his hand on his head and couldn't jump up at all.

Helpless, Butterfly Ninja had no choice but to take off his haori and wrap it around Butterfly Kanae.

Butterfly Kanae slowly opened her eyes and looked at the hugging herself. The butterfly ninja showed a smile.

Soon he found that he was naked, and his face suddenly turned rosy.

"Haha, Miss Ren, take your sister to change clothes!"

Roy did not embarrass them.

Hearing this, Butterfly Ninja took the shy Butterfly Kanae to change clothes.

It took a long time before they appeared again.

As soon as they came in, Butterfly Ninja looked at Roy angrily.

"What's wrong?"

Roy was a little confused.

"Why is my sister different from before?"

Butterfly asked angrily.

"Idiot, my sister will grow up too! Just like Shinobu has grown up!"

Butterfly Kanae touched the butterfly ninja's little head and said with a smile.

"But why is my sister so much taller than before, and her clothes have become too big? Her previous clothes were too small and didn't fit."

The butterfly ninja said angrily.

Roy looked at Kanae. She was at least 36E and 1.7 meters tall. The clothes she wore before were really tight. The

1.7 meter Kanae and the butterfly ninja Standing together, it's like an adult with a child.

No wonder the butterfly ninja is so angry

"No need to envy Kanae, Shinobu. If you also want to grow bigger, I can help you."

Roy touched his chin and said playfully.

"I do not want it! Butterfly gave him a blank look and decisively refused.

"All right! In this case, forget it and get ready to start the turning ceremony!"

"Eh? I...Do I want it too?"

Butterfly Ninja pointed at himself in confusion.

"Don't you want to be with your sister? You know, after I deal with Kibutsuji Muzan, I will take your sister and leave, and then I will be left alone all alone!"

"And Shinobu agreed to be eaten by me!"

Roy looked at the Butterfly Ninja with a devilish smile.

Seeing this, Butterfly Kanae couldn't help but feel pity for her sister. The simple Butterfly Ninja was the opponent of Roy, the devil.

Under his words , Butterfly Ren had no choice but to agree.

"But what will happen to Butterfly House if my sister and I leave together?"

Butterfly Ninja is a little worried.

Butterfly House also has her and her sister's stepson, Kurihana Rakanahu.

There are also Butterfly House's three little ones, Terauchi Kiyoshi, Nakahara Cheng, Takada Naho, and the medical girl Kanzaki Aoi.

If they choose to leave, then What to do with the remaining few people?

"This is a small problem, just let them all become my dependents. I just don't think the castle is lively enough!"

The Butterfly Ninja's worries are not a problem with Roy here. Rather, it plays into his own hands. Hearing this, the Butterfly Ninja became very angry and his little face bulged into a bun.

Roy couldn't help but poked her little face. The Butterfly Ninja was immediately discouraged.

His sister was resurrected, and the Butterfly Ninja no longer had to pretend to be himself, revealing his true and lovely side.

"Wouldn't it be better this way? Everyone can still be together!"

Kanae touched Shinobu's little head.

"All right! I just agree, but I still have to ask for their opinions!"

"No problem!"

Roy agreed with a smile.

Then the devil turned around and turned it on again.

"I give this order in the name of Roy Lucifergus, you butterfly ninja, become my familiar demon and be reborn as my soldier!"

Under the blue magic circle, a soldier chess piece slowly integrated into the body of the butterfly ninja.

Then the devil's wings unfolded, and the butterfly ninja successfully turned into a devil.

With the addition of the devil chess piece, the butterfly ninja's strength reached 100% in an instant. She reached the peak of an intermediate demon.

Due to the construction of her body, Kanae's magic power was a bit low, but because Kanae's original strength was stronger than that of the butterfly ninja.

So after turning around, her strength was also at the peak of an intermediate demon.

As the Feedback from the strength of the two women, Roy's bottleneck at the peak of the intermediate demon was immediately broken.

Huge power surged crazily in his body.

In an instant, he broke through to the upper-level demon, but the breakthrough did not stop, until he reached the upper-level demon. The stairs stopped.

Then there seemed to be a power awakening in the body.

Suddenly, a cold force emitted from Roy's body, and everything where this cold force passed was blocked by ice.

It spread to a radius of Inside, the entire Butterfly House was frozen.

However, under Roy's control, no one was harmed.

"Catalpa~~"

The butterfly endured the cold temperature and couldn't help but sneeze.

Although they were not frozen, the cold air emitted by these ice cubes was too low.

Even they who turned into demons couldn't bear it..................................................
