4. Parents.
Lord Death had gone to check on his son. He smiled...or at least, smiled as best he could with that mask of his, as he noticed Kid sound asleep at his desk. The younger Shinigami had passed out from exhaustion from spending the night studying hard for an upcoming test. There were pages of notes scattered about the room and books opened to various pages scattered about as well.
The Grim Reaper then gently lifted up his son, after a bit of effort due to Kid's weight, and began to carry him to his room.
"You've certainly grown quite a bit." Lord Death spoke in a somewhat joking yet loving tone as he tucked Kid into bed before turning out the lights and letting him rest.
Author's Notes: Don't ask how Lord Death can lift and carry a 500 pound Kid. Um, he has super-strength. Yeah, that's it.
