Zero Two being sprawled out while sleeping is an adorable image, and her sleeping while clinging to Hiro is even moreso. They start sleeping in the same bed after the battle at the Gran Crevasse, and for awhile, she practically sleeps on top of him because there’s a part of her that’s terrified he’s going to disappear. Even years later, there’s some nights where Hiro wakes up in the middle of the night with her holding his shirt in a death grip and her head tucked as far into his shoulder as possible.
