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

"What's the best way to defeat a person?" "Destroy beautiful things in front of him." "What if it's a magical girl? What about the kind of magical girl who has the power to protect everything?" "That's... it's also very simple." Youyu said with a smile. "That is to become the beauty in her heart when she knows nothing." (Raise her) "Then..." "Die in front of her." (Let her regret it for the rest of her life!) After all, "villains" are not within the protection range of "good guys", right? But... the actual situation seems to be a little different from what Youyu expected? Why did these magical girls want to lock him up after he "died"? The pace is a bit slow, please be patient to read it.
