So.. I've been thinking about how Toei gonna do the switch between Maya Imamori and Kohaku Shida as GozyuUnicorn and I think I've found a way: In ep. 20, Oto don't recognise Sumino, and that's because Sumino dosen't looks like herself... Just like Kinjiro Takehara wishes to be young and got it (switching from old actor Masaki Kobayashi to young actor Jin Matsumoto), Maya Imamori is actually Kohaku Shida in disguise, so she'll be able to catch Rei Gushima that kidnapped Oto, without him recognise her as well. So now that Oto is free, Sumino can reveal her true self to everyone.
