To assume she was being targeted but it was infact Shinoa all along… That is a horrible move for Shikama to pull more so when Mahiru took such measures to defend Shinoa, she was a confirmed target from day one.

With Mahiru and Saito’s plan, could have thought what she done were drastic measures just to ensure the plan could be carried out. Would feel a lot better, and it would actually make a lot of sense if it were Shikama and Tenri being directly responsible or her actions. Indeed it kind of absolves her somewhat, especially if it's a Shikama possessed me, made me do it like. Yet that also means they may well know of her plans with Saito, and Shikama and Kureto (since he would likely have heard these plans from Tenri) may have the checks in place for the joint Mahiru/Saito end game.

Quite a defining trait that Tenri has something in common with a history altering deity like being described across the board as a monster! That they both troubled Mahiru after removing Guren from the scene, how crude as well!

The thing is with Mahiru-no-Yo, half of her is the Noya demon, which together makes the overall demon have a kind of head in the clouds feel. At the same time she is also keenly aware of what is going on such as reminding Guren it is her orders he should be following. Then of course like you say for Mahiru’s part they knew full well that was not good news not just because Shikama was there but maybe because with less of a concept of time Mahiru-no-Yo was all the more startled since the time was up. Shikama right there, Shinoa has not tapped into her desires, would cause anyone to freak out. Could have also been one demon recognising the strength before her, that would explain the reaction if she was still in the dark of who was really masterminding these happenings.

Considering everything, whether she is still being manipulated, has something to come with Saito, or her own plans I do hope Mahiru can be the one to reclaim her sister back from Shikama. To fail despite trying everything, to see for all your plans they have fallen apart, to feel she has saved no one. Now more than ever with Shikama here, just makes it all the more important that even in her state Mahiru can find the power to make this right for someone she cares about.
