* The revelation at the end of the 2006 anime version that [[spoiler: Ayu used her "last wish" to: cure Shiori's illness so she won't die and leave Kaori bereft, heal Mai after she tried to kill herself and fully integrate Mai's power into Mai, ensure that Akiko wakes up safe and sound after her accident, and wake herself up from her coma. So, how did Ayu manage to do all that in only a single wish? Because she didn't wish anyone back to life. ''She wished for Yuuichi to be happy, and it just so happens that Yuuichi would be happy if the other girls were saved.'' Doing all that for Yuuichi's sake means, for fans who preferred playing Ayu's route in the game, Ayu's ''earned'' the right to be the official couple with Yuuichi.]]
** This is based on Ayu's encounters late in the other girls' routes in the game, where [[IWantMyBelovedToBeHappy she sees that Yuuichi is happy with someone else, wishes him happiness, and is never heard from again]].
