A magical girl with dementia? I picked her up and remodeled her!

My name is Bai Yu, the leader of the monster organization. In the battle with the magical girl, I successfully regressed her to a child and tricked her into becoming a newly created monster soldier!
The next step is to transform her from scratch and train this magical girl into a monster cadre. Just thinking about it makes me feel very interesting!
……
My name is Meng Yue, the strongest magical girl. The weird leader didn't know that his magic was useless to me, but in order to find out a secret, I pretended to be insane and successfully infiltrated the organization.
But I didn't expect that the benefits of the monster organization would be so good! Not only is food and accommodation provided, but there are also holidays! You know, magical girls work all year round and have no benefits. If it weren't for the so-called justice, I would have quit long ago!
I don't want to go back~~ Or I can just aim to become a monster cadre! This way I can destroy the monster organization from the inside, and then... and then...
I can't remember! Let's deal with these damn magic girls first! I don't understand why you guys are working so hard without even a monthly salary? Why not join the Monster Organization and enjoy the high welfare benefits!
Today is also a day for me to fight for the leader as a monster cadre~
