Phantom of the Idol

Info:

Yuya Niyodo is on the verge of being fired from his job as an idol in the two-man group ZINGS, due to his poor and lazy attitude, when he meets the ghost of Asahi Mogami, a popular idol who died a year ago in a traffic accident.[2] Niyodo gets her to possess him and do his job for him, causing him to gain a reputation as a strange idol.
