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

"Fusion?"

Listening to what Youyu said, Bai Yu lowered his head and looked at the bottle in his hand. After hesitating for a while, he said:

"Sorry, Youyu, what you said... was really too fast, I didn't quite understand."

"You said that this bottle can fuse power... But, did you come to a conclusion so easily? It seems that we still know nothing about it now?"

"If we do this, there may be some accidents..."

"So, I just said 'maybe'."

After taking a breath, looking at Bai Yu's worried face, Youyu "calmed down" and said:

"Just now I was a little too excited, Bai Yu, mainly because of the feeling this thing gave me... It is indeed very useful."

"After all, this bottle seems to be a pure 'technological' creation. Although it seems to have the power of negative emotions on the outside, it has nothing left inside. It is just a blank."

"As long as you fill it with something, you can quickly get feedback and see the effect."

"And I just tried it and found that it is true."

"But... judging from the current situation, we have just got this bottle in our hands, and we still know too little about it."

"If necessary, I will test more after taking it back."

"...Okay."

Seeing that Youyu insisted on taking the bottle back, Bai Yu thought for a while, and finally sighed, nodded and agreed.

Then he said:

"Then, Youyu, if you find any abnormality in this bottle, remember to throw it away immediately."

"...I don't want you to get hurt again."

"Definitely."

Nodding, after putting the bottle away, Youyu looked up at the dark sky, then looked at the quiet environment around him, and said:

"Then let's go back now, Baiyu."

"After all, you should be very tired now, so many things happened today."

"...Yeah."

Nodding, Baiyu, who was thinking about many things in his heart, absent-mindedly put his hand on the blue gem on his neck and canceled the transformation.

Seeing this, Youyu, who was about to propose "cancel the transformation after returning home", also stopped talking in time and canceled the transformation in the same way.

Then he silently followed Baiyu, who had already started to move, and walked on the way home.

"Today's plan should be completed."

"But because many things are squeezed into this day...so the impact on her is still quite large."

"So now...let her think about it carefully first, so as to prevent her from not being able to sleep later."

Looking at Bai Yu's profile, You Yu thought.

Then, the two returned home in silence.

...

————

After returning home.

Because Bai Yu was really tired today, You Yu also suggested to her that she go back to her own bed to sleep, and he would sleep on the recliner.

On the one hand, he thought that it was not good to occupy someone else's bed all the time, and on the other hand, it was because...Bai Yu now really looked like she needed a rest.

So he took this opportunity to put forward this suggestion.

And this time, Bai Yu did not hesitate like before, saying something "good for him" and forcibly rejecting his request, but nodded and agreed directly.

If it were the same as before, it would not be like this.

So, maybe it's because she has figured it out in some aspects, so when facing this kind of problem, she is not so "stubborn".

It's a good thing.

"..."

"Youyu...Aren't you going to sleep yet?"

In the room.

Bai Yu, who had just finished taking a shower and pushed the door open, saw Youyu still sitting at the table and asked.

"Ah, I want to study this."

Hearing Bai Yu's voice, Youyu turned his head, shook the bottle in his hand, and said:

"It may take some time... Bai Yu, don't worry, just go to sleep."

"I will leave your room in a while and won't disturb you."

"...Is that so."

Looking at Youyu, Bai Yu was silent for a while, as if she remembered something, and then said:

"Wait for me."

After that, she turned around, pushed the door and left the room.

Seeing her leave, Youyu continued with his work without thinking too much about it. After all, he was really studying the use of this bottle.

Studying how to use it reasonably... on the magical girl.

"..."

"Tap——"After a while, Bai Yu walked in with a voice.

In her hand, she was holding a plate with a coffee cup on it, which contained the hot coffee she had just brewed.

"Youyu."

After pushing the door open, Bai Yu found that Youyu was still working hard. She called his name softly, and after he turned his head, she said:

"I made you a cup of coffee, Youyu. If you want to stay up late to study this bottle, then it... can help you refresh yourself."

After saying that, Bai Yu paused for a while, and thought of a "common sense" about Youyu, and continued uncertainly:

"... Maybe, I don't know if it will work."

"It's okay, Bai Yu."

After standing up and taking the coffee from Bai Yu, Youyu smiled and said:

"It's just right now... I really want to drink coffee."

"After all, I used to have the habit of staying up late, so drinking coffee... has gradually become a habit of mine."

"It can be said that it is an indispensable part of life. Thank you, Bai Yu."

"Yeah."

After seeing Youyu take her coffee, Bai Yu breathed a sigh of relief , a warm feeling rose in her heart, and then she tilted her head slightly, looking at the "drawings" that appeared behind him at some point, and then said:

"Then, Youyu, you must pay attention to rest early, don't stay up too late."

"In the future... we still have a lot of time."

"I know that, Bai Yu, are you going to sleep now?"

"... Yeah, ah! By the way, Youyu, you just need to study here, it's still very hot outside without air conditioning, don't worry too much about me."

"I have a feeling that I will fall asleep soon."

"... Really."

Listening to what Bai Yu said, looking at her current expression - a very convincing look, Youyu nodded without hesitation and said:

"Okay then."

"Good night, Bai Yu."

"Yeah."

...

So, after watching Bai Yu go to bed and quickly fall asleep, Youyu turned off the lights and lit a desk lamp for his position.

Then he looked at the bottle in his hand... and the "drawings" that kept flashing images, and continued his research.

"So... Yuyu, what are you doing now?"

After hearing the question from Mamba in his body, Yuyu, who was sitting at the table, responded to Mamba while performing the movements in his hands:

"I'm researching."

"See if we can use artificial intervention..."

"Let the magical girl gain a strengthened form."
