Yami to Boushi to Hon no Tabibito EP13 - Lilith

Lilith lashes out at Eve for abandoning her in the Great Library for what seems to be tens of thousands of years and Eve tries to make it up to her. Lilith notices that Eve misses Hazuki, who seems not to have returned to the correct book-world. Alone again, Hazuki reflects on her dreamlike adventures, but suddenly sees Hatsumi returning to the house. History repeats itself, like a universe reset, but Hatsumi does not glow and disappear at the stroke of midnight. Instead Hatsumi and Hazuki share a passionate kiss and then a cuddle. Hazuki awakens the next day not remembering anything, but notices the signs of Hatsumi's future rebirth as her child.
