Asagiri Gen used to be a light sleeper, but he’s gotten used to how peaceful things are after the conflict with ... everyone, basically, ended. It’s more difficult to wake him now, and dawn doesn’t automatically get him up. Gen seeks out heat and wraps around it.

Yuta is also a heavier sleeper, but he’ll get up early pretty easily and happily. There’s plenty to do in a day! He’s definitely cuddly in bed, he likes being the big spoon.

Izuku sleeps in as late as he can, and he’s one of those starfish types. He’s not used to sleeping with others, he’ll need to practice sharing some day without hogging all of the blankets.

Zechs sleeps lightly and wakes up early and has discovered cuddling while sleep is happening is actually pretty great? >.>

Dabi will fall asleep anywhere but sleeps super, super lightly. Anything can wake him up. Cold resistance means he’s not a blanket hog but his staples might snag on clothes, or at least he imagines they might. Good thing he’s used to accidentally popping those out.

Tsukasa has gotten used to cuddly Gen sleeping. He doesn't want to go back.
