Haruka Nanase, who was born with the ability to see ghosts and gods, is very bold, but Makoto Tachibana who grew up with him is very timid. For the sake of his friend's mental health, Haruka never told Makoto that he could see ghosts and gods.
Until one day, they saw a disgusting-looking ghost at the same time. From then on, they lived a life of swimming around, seeing ghosts, and finding corpses.
Seeing that the peaceful life in the past has irreversibly changed, Haruka decided to find a way to change Makoto's timidity out of consideration for his friend's mental health.
Makoto: (horrified) Ahhh! (Hiding behind)
Yao: (expressionless): This is a disease and it needs to be cured.
The character's personality is closer to the original novel "High Speed" than the animation. Since it can be seen as a story that develops in a parallel space, the character's growth environment is slightly different from the original work, which will cause certain deviations in personality.
