Bleach theory re: Masaki

WHOA you guys.  WHOA.  I just realized something about Masaki Kurosaki.  (Ichigo's mother)

Spoilers up to chapter 530

What we know:
- Masaki came from a long line of Quincies, was orphaned, was taken in by the Ishida family and engaged to Ryuuken.
- She met Issin and saved his life when he encountered a Vasto Lorde-like hollow way back when.  A hollow that bears remarkable resemblance to Ichigo's full release hollow.
- She was killed when Ichigo was 8 years old, when Ichigo got lured by the Grand Fisher hollow.

Here is what I think.
- Masaki defeated the Vasto Lorde hollow by using Sklavarei (absorbing its spiritual body and assuming/adopting its powers) and passed this hollow essence to Ichigo.
- She was not killed by Grand Fisher.  Looking back to the first encounter in the original manga (chapters 21-24) Grand Fisher never says it killed Ichigo's mother- it says it can't remember what happened that long ago.  It transforms its lure into Masaki because it stabbed Ichigo with its talons and figured out his weakness.
- Masaki was too powerful a Quincy to be killed by Grand Fisher.  Chances are, it was placed or used as a distraction and something or someone else killed her.
- Ichigo doesn't have an asauchi because he was part hollow from the very start of his life and he manifested a zanpakuto in the same way that Arrancar manifest one (according to the bleach wiki, their special powers/abilities are sealed into the form of a sword).  So the zanpakuto that he manifested after training with Urahara is his Arrancar zanpakuto.  All his shinigami powers are borrowed/inherited abilities, first from Rukia, then from his father, Isshin which is why they have an identical attack: the Getsuga Tenshou.
- He became a Visored and a Fullbringer simply from having the spiritual powers to do so.

This could mean:
- Masaki was killed by someone that has yet to be revealed.  I am placing my vote on one of the Vandenreich, or possibly Yhwach himself.  Someone with a vehement grudge against shinigami and with the intent to assassinate/punish Masaki for falling in love with a shinigami.
- In addition to having Quincy powers, Ichigo also possesses an entire host of Arrancar abilities.  We've already seen his hollow take two forms/releases (that is, full-bodied Hollow and not the Visored mask alone)- one during Urahara's training (first stage, sealed zanpakuto?) and during the fight with Ulquiorra (true form, released zanpakuto), Maybe he has yet to/will achieve a Resureccion- OMG!!!
He may reforge his zanpakuto once he realizes this and decides to consciously activate his hollow abilities.

BAM.  i am so patenting this as my official headcanon right now :P
