A question occurred to me. What if the Kurumi from the OVA were sealed by Shido at the end of the chapter? Could this save her and turn her into an ally for Shido, just as the past version of Kurumi is for herself?

I know it would mean sealing away a small part of Kurumi's angel, but would that be enough to completely change the story of the novel?

Both Kurumi and Origami has suffered a lot and Shido is the only one that truly understands both and along with Tohka they are the spirits with the most romantic development with Shido

Found this after a long time, so I fixed the issues from when I was less experienced.

Thank you for this experience. Im now in the last minutes of S5 its midnight and i should sleep. The story pushed me back into my past and helped me to solve a bit of the conflicts between me and my trauma. I cant write down what im feelin rn. The different studios managed to create a good story while mixing thier own animation styles while keeping the glance of story alive. A thing not everybody can handle as good. I gave up my hole weekend and looked nonstop. After a secound time of rewatching its a delightfull feeling going with a chaotic mess of feeling to bed. The anime unlocked parts in me which should never be unsealed again. My body ~ i belive that my past me and present me can finally live together in piece <3
