The illustrations portraying one or more characters sleeping peacefully are tagged Mamoritai, Kono Negao (守りたい、この寝顔, I want to protect this sleeping face). Today we collected those illustrations. Enjoy!
Isn't it a natural instinct, wanting to protect someone who's sleeping peacefully? It's important to protect this temporary peace of mind, while we're always busy with everyday life and, in some cases, with life-threatening fighting.
