Ok Isshin is a Captian Level Soul reaper that left Soul society. I believe he may have left along side Urahara and The cat lady(fForgot how to spell her name). Now i think that Ichigo mother protected him from Grand fisher. I believe she was able to see Spirit and saw the hollow. That way in the way she was laying it was like she covered her son from the hollow. She could have absorbed some of the spirit energy from her man when they did the nasty thing. OR she could also be from Soul society and be a high level Soul reaper. She could have been Captain, level also. That could explain. Ichigo high level of spirit energy. All that energy cant come from just the father. If that tur then Isshin must be stronger then Aizen if that the case. And that without unleashing his Soul slayer.
What do you think? COuld Isshin be from a noble family? could ichigo mother be a Soul reaper and whent with her husband? Could Isshin be able to defeat Aizen without releasing his Soul slayer? Am I Insane?
