You know, seeing these recent doujins actually working to give us more about the complexity of the characters it's really great, even the scene with the umbrella shows us the great pride Sumireko have.
Stealing the strap was both a way to make Mahiru come after Sumireko seriously to train and become stronger, and to keep her loved ones(both Mahiru and Shinya) by her side.
We have to recall that Mahiru is insane(remember, she's the pyschotic one, not Shinya), it's her character and it's exactly what Hanabusa loves the most about her, more likely this was the only way Hanabusa could think about to atract and interact with Banba eficciently(after all, it's freaking hard to talk with the easily scared Mahiru). Thats way i love so much this pairing, i consider Sumireko the character with the most interesting love out of all the pairings, she liked and loved Banba from start, not because she has a completely pure heart like Haru neither because she's noble and perfect like Chitaru, Sumireko takes a liking to both her good and bad traits, specially the bad ones, indentifying herself with someone who embraced insanity to survive alone in a hard and cruel world from a young age just like her, they have much in comon deep down there.
In a darker way, i see "I will return to you this strap, as a relic" implying someday Mahiru will kill Sumireko and takes it back, making it a relic from a dead one, but being realistic, neither Shinya and Mahiru really wants to kill her, neither they can, Sumireko is far too strong and exprienced for them. I agree with Proto1210, they will grown together as they days passes, it's not like Mahiru is a complete monster like Takechi, she can easily get over this "relic" stuff like in the anime while learning to get close and talk to people even without Shinya, and eventually loving Sumireko in the same way, when this happens, Sumireko will return the strap, as a relic, the treasured memories of their lives together.
If Ichinose Haru doens't need to be a lonely queen, Hanabusa Sumireko will see the doens't need to be one as well.
