Returning to Tokyo to Form a Phantom Thieves’ Group with Showbiz Girls

I put on the mask given to me by a mysterious girl and returned to Tokyo's past with a mysterious System. In a parallel world where the supernatural was beginning to emerge, I used my knowledge of the future to write songs and compose music, act, and invest, quickly making a name for myself in the entertainment industry. With the System's power, I formed a phantom thief group with the girls and rose to legendary heights behind the scenes, unknown to all!
