Waaaaaaaaaaaaaaaaaaaaaaaaaiiiiiiiiiiiiiiitttttttttttttttt!!!
What. The. Heck?
I thought that Keine disappeared there for a moment, or is Mokou with Keine under the autumn sky was a flashback and... and... the scene with the potato was also a flashback?
Or... or... was... was it just me who was imagining things?
Looks more like it was a dream, where she woke up with her hand held above and Kiene sneezed. Also probably something to do with the "Why does autumn make us feel lonesome?" part.
Doesn't seem to be anything deeper.
