1 Work in Kamio Haruko
What happened later of "Air" Manga / Anime editions that I believe. Please careful, it contains some spoilers.
Themes of two world lines:
A: Growing up of Misuzu
B: A Remedy for Haruko
World line A is based on manga edition as canon, however, most people may think a de facto "Alternate Universe - Canon Divergence (Post Series)" or "Fix-it".
