invisibility manga?

[EchoGirl]

looking for manga where the main protag was a mangaka who awakened to invisibility powers and also a female aspiring assistant who looked up to him, i think he killed someone or so but the person/corpse also stayed invisible? and the editor found out/tried to take advantage of the power
