Momo noticed the boil coming before Junko did. He barked, nipping at Junko's heel and getting the ghoul's attention before she could be completely run over. Whirling around, the ghoul gasped and managed to save herself from being crushed. Her hair managed to wrap around the boil's middle and slow his fall, though it didn't completely stop it, and she was able to catch one of the books, but not the rest.
Sayuri and Kuro just stood there yapping.
"Oh my gosh! Are you okay?!" She asked as she got down on her knees to start collecting fallen books.
