Later, Doug realizes that the kids have all grown up without him noticing:
The child he picked up in the slums has become a member of the Detective Agency, though his eyebrows are just as distinctive as ever.
The child he found in a seaside town has taken his little sister aboard a ship and become a doctor feared by pirates.
The child hunted by monsters because of his spiritual powers worked hard and became a renowned onmyoji.
The child abandoned for missing organs fights side by side with a child called a ghoul, carving a path through a world where Celestials conspire with demons.

Doug: What hardworking kids! But is there something a little strange about how they treat me?
System: Have you heard of a certain phrase?
Doug: ?
System: Filial devotion gone awry.
Doug: ...
Anyway, who doesn't love doggies?

Notes:
▼ A familial bond with hints of romance, plot-focused, pairing undecided.
▼ The protagonist looks like all kinds of dogs. He's a dog most of the time early on, and becomes human later.
▼ Farming and taking it easy, with occasional appearances as a big shot.
Theme: Doggies are the best in the world!
