- Ichigo's bond with Zangetsu, Hollow Ichigo, and Muramasa. Best exemplified with this line, where Ichigo highlights the greatest difference between him and Aizen.
"In the end, I chose not to be alone."
Muramasa: "Is there now any part of you that hates me?"Ichigo: "No."Muramasa: "Then I am rewarded."
- Muramasa is the one that reminds Ichigo that You Are Not Alone. And for giving him his power, all he ever asks of his new wielder is that he never let him go.
