Shachou, Battle no Jikan Desu!

Fushihara-san often works overtime like a corporate slave, even after her coworkers have left for the day, spending the majority of her day shackled in front of her office computer. When a ghost in the shape of a young girl who is said to haunt the building notices Fushihara-unhealthy san's position, she decides to scare her out of the office in order to reduce her tension. The ghost's overwhelming sweetness, however, has the opposite effect and encourages Fushihara-san to put in even more effort. Even so, as the two of them spend more time together, the existence of this sweet soul will only make Fushihara-life san's more positive and joyful.
