In the opening of one of the new anime series this season called "
Ulysses:
Jehanne Darc to Renkin no Kishi", there is this one scene that's been
grabbing my attention. It's where this unknown girl wears a helmet of some
kind, and by doing so her hair grows and her breasts seem to expand.
In this week's episode(
episode 5), that character was revealed to be
one of the main cast's young female character named "Philip". In the last
part of the episode, she puts on the same helmet, which seems to be cursed
of some sort, and then she suddenly becomes engulfed in dark power and
trembles in pain. It is pretty much confirmed from this and the opening that
the helmet ages her into an older alter ego that will be fighting the main
characters.
The episode sadly cuts off right there(although the very last part seems to
at least show her neck expanding), implying that she goes through the
transformation off-screen. However, since it seems likely from the opening
that she will put on and take off the helmet a few times while hiding the
transformed alter ego's identity, if we are lucky, there will be an event in the
later episode where it will be a shocking reveal to the main characters, and
she will have a proper transformation sequence while admitting it.
