Haunting You (Can you help?) - Chirisu

After the meteorite hit Shibuya, Arisu's life ended up in pieces. Now hospitalized, he tries to recover both physically and emotionally, but it's harder than it seems. It sure doesn't help that there's a weird man hovering around him, cryptically asking for his help.

Or, Chishiya is a ghost that's trying to move onto the afterlife, but apparently Arisu is the only one that can help him and he's been difficult about it.
