Heh, those parallels :) Aika and Akira are very similiar in a way and so is Alicia relationship with Akira like Aika and Akari :) Seeing Alicia and Akira as young one was great moment.
Also, it was very surprising to learn that Aika is actually heir to Hime-ya, although I should kinda expected it after I saw her noble room.
Wonder how is third fairy, Alice's master.
