I lived my whole life as a s*ave, bound by a leash. But there was one thing that I was able to choose for myself: the place where I would die.“…Any last words?”My only friend asked me in a calm voice, and I quietly replied as I closed my eyes.“Waaaah!”…Waaaah?To cut to the chase, I was reincarnated. And not just as anyone, but as my friend’s youngest grandson. So, what am I going to do now? Well, what else can I do?“I’m going to cause chaos.”

There are quite a few time travels in these years, but he is probably the first one who suddenly and inexplicably time travels during the execution of a mission. A new world, a new beginning, may be the best result for him. but……
Animals transform, well, he’s calm.
There is no woman, well, he is calm.
As a female, she still needs to marry a guy who can transform…Calm down, draw your knife, and prepare to kill someone.

Aizel has been depressed since he was a young man. From being tormented in school to being treated as an outcast solely because he is an antisocial person, the only things that kept him going were novels, manga, piano, and sword practice.He never anticipated being transferred to another world while drunk by the side of a lake under the moon. The world with mana is filled with superpowers, magic, and monsters, and he is unsure whether he is dreaming or not.Only to discover later that he possesses a power that may be called the most deadliest thing he could have ever imagined, but with limitations and drawbacks...“All of the kingdoms, magic, and everything about Xelgar fascinate me. But what Alora said makes me very curious.”“I knew I could easily use sword skills, fire skills, and techniques because I had seen and read so many anime and novels. I still can't believe that there is now a unique power as well.”“Is it true that I possess the power of imagination, as Alora claims? Isn't that a little overpowering? However, I was still unable to use some techniques and skills in the fights. The power has a disadvantage and a limitation.”“Is that because of my cracked core? If I can somehow recover it, will I be able to do anything just by imagining?”
