Raise a magical girl and then regret it for the rest of your life? !

"...I didn't expect there would be an unexpected gain."

After watching Youyu and Baiyu complete their transformation, the "rat" who had been standing still and watching them... referred to as the Rat Monster, suddenly made a sound, and two green "big eyes" flashed with light.

And this voice... Youyu was very familiar with it.

Because the voice coming from the Rat Monster was the voice of the gray shadow who had fought with him last time.

So, after a second of "surprise", Youyu's voice suddenly became low, and then he tightly grasped the big sword in his hand.

"Looking" at the Rat Monster, the momentum on his body began to gradually become bad.

"...Sure enough, if you don't kill your body, you can't die."

"You dare to appear in front of me... And you talk more nonsense than last time."

As he said, Youyu raised the big sword in his hand above his head, as if he was ready to attack at any time, and Baiyu, who "disappeared" at some point, was accumulating strength in the dark.

However, the rat monster did not make any move, but just stood there.

Gray Shadow continued to speak with a mocking voice:

"Nonsense? Haha, it doesn't matter... After all, I know that I can't kill you with just an 'experiment'... I'm not that stupid."

"Besides, I need you to cooperate with me to conduct the 'experiment'."

While speaking, Gray Shadow remotely controlled the sensing ability of the rat monster, concentrated all the sensing power around him, and roughly determined the position of Bai Yu, and then said:

"I have heard your name from the mouth of the snake knight... Youyu."

"So, as the first one to be transformed by him, I want to ask you a question..."

As he spoke, Gray Shadow's tone gradually became disdainful and sarcastic:

"Do you think that you have gained such power now by chance?"

"Do you think... that the snake knight who created an accident like you... will just sit back and let you stay like this ”

“Do you think… he really has no backup method to deal with you?”

“…”

“What the hell are you trying to say?”

“My meaning is simple and clear.”

Gray Shadow said directly:

“Your change may be within his expectations and plans, and my actions… may also become part of his plan.”

“I don’t really understand what that guy is thinking, but I can be sure of…”

“After I lose my interest in him, he will ‘kill’ me without hesitation.”

“So… based on this premise, I want to give you an ‘advice’.”

“That is – now, let’s join forces to kill that ‘snake knight’.”

“Then, slowly deal with… things between us.”

“…”

After listening to what Gray Shadow said, You Yu was stunned and silent for a long time.

After a long while, he said in a complicated tone:

"... As expected, the brain circuits of people like you are strange. Listening to what you say... is a complete waste of my time."

As he spoke, Youyu's voice suddenly became low, and he said to a certain existence:

"Bai Yu, it's time to act."

"Yeah!"

The next moment after this sentence was spoken, a huge splash of water suddenly "exploded" around the mouse monster, completely covering it.

That was Bai Yu, launching an attack.

————

"... Anyway, the parameters should be adjusted enough."

The gray shadow in the distance was not surprised to see this scene. After all, the so-called "cooperation" was completely impossible. He knew clearly that the reason he proposed it was just to delay time, temporarily adjust the parameters used to deal with the magic girl, and see if he could interfere with his mind.

And that Youyu... had the same idea as him in some ways, so he chose to follow his words and let another magic girl secretly attack his mouse monster.

The reason why he didn't launch an attack himself... maybe for some purpose, he let the magic girl attack the rat monster.

And his purpose... based on Gray Shadow's previous judgment, he can more or less guess it.

"... But, you can't live to that time."

Muttering these words, Gray Shadow, who already knew the general ending, didn't observe the situation of the rat monster anymore, but turned off the image and continued his own experiment.

Anyway, when the rat monster dies, the information on it will be transmitted to Him.

After collecting the information... He can make it according to the data.Make a more powerful "Mechanical Negative Beast".

Or rather...

"Based on this new power..."

"Knight Negative Beast."

...

...

The perspective turns back to Youyu and Baiyu.

"Sizzle...Sizzle..."

At this moment, the rat monster has been beaten into a pile of scrap metal and thrown on the ground.

And this scene... is not beyond Youyu's expectations.

After all, it's just an experiment.

"It's almost good enough to be able to do this."

Looking at what only he can see - the database that he "exchanged" from Gray Shadow last time and forcibly synchronized, Youyu thought.

Judging from the results of the database analysis and the battle between Baiyu and it just now, the power of this "rat monster" has reached the passing line - that is, it has reached the "blank slate" level that he pretended to be when he didn't use the card now, which is already pretty good.

After all, reaching this point means that the "rat monster" experiment is much stronger than the previous experiments of Huiying, and has the opportunity to fight the magic girl head-on--

So, as long as Huiying continues to experiment according to his own plan and creates more and more powerful "knight-type negative beasts"...

Then the final effect he wants to see later is just around the corner.

"But before that..."

"...I also need to try my other plan."

Thinking so in his heart, Youyu looked at the bottle in Baiyu's hand that she couldn't "destroy" and walked over slowly.

Then, after saying "Let me see what to do" to Baiyu, he easily took the bottle in her hand.

And just after Youyu got the bottle in her hand-

"Wow!"

Instantly! The bottle suddenly changed! All the dark energy inside was eliminated... No, or it was "changed"! "Fusion!"

And what it "fused" and replaced... was the energy mixed with magic and negative emotions in Youyu's body.

"... What's going on?"

Looking at this strange scene, Bai Yu asked curiously.

Looking at the bottle in his hand, after a moment of silence, as if he understood something, Youyu replied:

"Bai Yu... I found that this bottle seems to have a fusion effect, so... I just put a little bit of my magic in it, and they completely merged without any rejection reaction."

"This is really... incredible."

"And, Bai Yu, maybe we can take advantage of this opportunity--"

Looking up and looking at Bai Yu, Youyu said:

"Relying on this bottle, let your magic and my negative emotions be unaffected by anything--"

"Fusion."
