Not sure if we should release Hikari Saga 2 until after Mebius ep. 17 is done, since it kinda contains a bunch of spoilers for that episode.
But, related to the discussion on Sennetari's LJ about Hikari and Serizawa
Excerpt from the translation, Zoffy speaking to Hikari:
Zoffy: Have you forgotten about the human you've become one with?
Ultra Mama: There is one who does not wish your death.
Zoffy: His wish is the reason you're alive.
So I guess my theory's wrong, and Serizawa's still kicking around but with Hikari doing most of the driving. It gives him a more solid-seeming reason for not coming back earlier... But really leaves me wondering what the heck he and Hikari were thinking letting Ryuu do the driving at the end??
A completely random thought just hit me: I think Tsurugi-possessed Serizawa is the only case I know of where a hosted Ultra is in charge while in human form. All the rest of them the human calls the shots while short, IIRC. (Except for what I've seen of Jack -- all three or four episodes. He seems a bit persnickety. "No, I don't wanna change now." ... later ... "Yeah, who cares if you have other things to do, we've got bigger matters -- if you'll pardon the pun -- to deal with now." Very much a will only change at his will kind of Ultra.)
