or it could not end at all...
seriously if they made a new season with Ai as the main or a prequel series with Alicia as the main
i would cum buckets upon buckets
better yet, a small ova series
we find Akari and co attending a highschool, however Akari feels uneasy and while the series maintains its slice-of-life feel, we slowly delve into the darker side. fragments of memories return to Akari, and she slowly remembers, as so do all the other members of her group
and of course Akari and Ai are in their "young" versions
eventually we find out that in an accident Akari and co was made comatose, and has been so for a month, and Cait Sith was keeping them in this dream world to keep their minds alive while their bodies healed.
tears are shed, bricks are shat, and then they all wake up.
