Evidence for Ikuko=Yasuda:

1. Ikuko = "many children"

2. I don't think it is a stretch to assume that Tohya's early memories of meeting Ikuko may have been at least a little manipulated.

3. At the beginning Ikuko seemed quite shy to me. It took time until she changed to the personality she had at the end.

4. We have no idea what Yasu did in the last 2 years before the incident. But if she planned to leave the island, she would have to have a stable identity. Both Shannon and Kanon were adaptable for outside Rokkenjima, "Beatrice" however, as she mentioned herself, cannot just leave Rokkenjima. So she would either leave as "herself" (Yasu) or create a new identity alltogether (Ikuko). And if she wanted to live with that new identity, she would have to CREATE it first (Ikuko's house etc.)

5. Yukari mentions about Ikuko having a "timeless feeling" and seemed like she would never age. We know that Yasu had talent in "appearing as being younger".

6. The last scene in the orphange suggests that Ange replaces Yukari, Battler replaces Tohya and Beatrice replaces Ikuko.





Oh and by the way: "Tohya" was foreshadowed in EP6 when Ange asked why in publicity there was a "young man" instead of a woman as Hachijo Tohya
