So.

With the revelation that Helheim is NOT the future and not an "Alternate Universe", just some sort of alternate dimension, I'm really scratching my head on who and what Alt Mai is. Is she another Overlord, taken human/spirit form? Is she a physical representation of a Lockseed?

I'm confident in my thought that DJ Sagura is actually the main Overlord, but Alt Mai still confuses me.

My best guess? She's a Lockseed (the final Apple one) and took the form of what all three Riders (the only 3 that have seen her) want the most - Mai. We know Kouta wants her, as he's super giddy when she's nice to him. Obviously Micchy wants her because he's trying to kill Kouta over her, and Kaito has shown some affection (in his own emo way) towards her.

But obviously Kouta will get her because unlike Micchy who wants her for himself and Kaito who wants her for what she can do for him, Kouta wants her to protect her, which is the most noble and thus, the most deserving. The forest will choose him, and she will turn in to the Lockseed for him to use. Probably after something happens to Mai.

Just speculation.
