Reset

The reset is a key moment that occurs during Layer 13. Because of all the damage she has caused to the world and especially to her friend Alice, Lain chooses to start the world over while erasing her own existence.

As a consequence, all the characters who were playing a role linked to Lain returned to their normal lives. The only people who noticed Lain's absence or had any impression of her left were Iwakura Yasuo, her surrogate father, and Mizuki Alice, her best and perhaps only friend.
