Spoiler for 4th Movie Plot Details:

Now that I gave it a little thought, Shiki's circumstances are very similar to Touma's (from Index), but the way the two shows handled it is completely different.

Spoiler for 2nd & 4th Movie Plot Details:

Something I can not really get || accept is that during the 2nd and 4th chapters it is implied that SHIKI (male) was in control constantly, but rather let shiki (female) act most of the time. OK, this was the protecting and loving part of SHIKI, but ... when he disappeared, shiki should not feel so disconnected with her past, since she was practically the active "personality". Hence almost all of their memories should be a result of her actions and thus except from the loniless and insecurity, she should not feel any kind of disconnection!

Spoiler for Question based on the 4th Movie:

And by the way, have I missed it or there is no reason given for SHIKI's disappearance?!?!?
