A guardian spirit, as the name suggests, is a spirit behind you. It is also known as a ghost. It can be a benevolent spirit, usually a human's guardian spirit. But it can also be an evil spirit. If the spirit behind you is evil, then you're being haunted by a vicious ghost, and death can't be far away.
Rei Furuya knew there was a guardian spirit watching over him. It had been by his side for as long as he could remember.
He's a good ghost. He's never hurt me. He even avoids waking sleeping kittens, so I trust him completely. That was Rei Furuya's explanation afterward.
Kiyoshi Asaba, a cat lover who can't stand people: ...You trusted him a little too soon.
Perhaps he can't appear in front of people, but he has always watched over him quietly from behind.
Kiyoshi Asaba, knowing what Rei Furuya was thinking: ...Ah, he loves me so much.
Actually, the protagonist can take on a visible form or become human, but he's lazy, and ghosts can float... This is the story of a protagonist determined to be as lazy as possible, whose adopted kid keeps dragging him forward. What else can he do? Keep raising the kid, of course.
