does anyone know if this is a manga and what the name is 😕

It's an image from a Get Backers artbook. Note, though, that the series is actually... shounen. Slashy at times (yes, the art is official), but shounen.

thanks!! I knew that it looked familiar but I didn't remember though I watched the anime 😀
