Kaito is a 17-year-old high school student who just wants to live his life to the fullest, but the routine life he is set to live is the exact opposite of what he wants.
To escape it all, he stays rebellious, aiming to do whatever he wants every day. Through this lifestyle, he got himself killed, but fortunately for him, he was chosen to be reincarnated into another world!
In the other world, he meets with a girl named Rina. They venture to a dungeon with text that is unmistakably Japanese kanji. But this world uses a different language; why is this text here?
What is happening in this new world that warrants Kaito’s need to be reincarnated? Is there a Demon Lord that needs to be defeated? A civilization that needs building? Or perhaps, this world is just in need of a real hero…
Whatever it is, Kaito is going to have fun either way!
