Shuu, Ayano and Sharon are fighting as a cohesive unit, but against Kanna the best they can do is maintain a stalemate. Enter Tabula Rasa Kisara, who despite having no memories decides on her own not to let what seem like nice people die in a battle with a not-so-nice person.
The addition of Kisara to the battle definitely gives Team Shuu an edge as Kanna starts to flounder a bit, but then she summons three powerful demons, which means all of the other demon hunting contractors spring into action, for the city that’s the only home they have, for honor and glory, and money too.
When even Kisara can’t quite get to Kanna’s heart to seal her, Shuu lends her power in the form of a kiss. Turns out their old contract terms work just fine, and the newly re-Hot Topic’d Kisara has a stiff second wind at her back. She keeps Kanna occupied enough for Shuu to fire his demonic bullet. Asmodeus flees from Kanna, and Kisara carves her into ribbons, sending her back to whence she came.
In the aftermath, while some demons made it to the city, there were no civilian casualties, so the contractors call it a victory. Sharon admits the Abbey will still be coming for Kisara, but at least today, Sharon won’t be the one to kill her. Wondering where a demon girl fits in a human world, Kisara gets a supportive hug from Ayano.
The Hachisukas continue their sibling rivalry for control of the city—and international coverup to maintain their autonomy. Sharon makes a joke to Ayano about spending the night with Shuu before boating off to face inquisition. Shuu visits his parents’ grave and promises his work isn’t done, but he’ll do it the right way this time.
As for Kisara, she wants Shuu to teach her all the memories she lost, which apparently includes fulfilling the role of his girlfriend. Things are about to get hot and heavy in his apartment when the lights come on to reveal Kanna gobbling up all the food in the place. While the authorities kept her restrained in the bowels of city hall, this is only the latest of several escapes.
Those escapes result not in her unleashing demons on the city or causing any damage, but inserting herself back into Shuu’s home and life and voicing her disapproval of Kisara. Now Kisara has in Kanna what Ayano has in her: a younger rival for Shuu’s attention.
With Kisara, Ayano, and now Kanna all pointing weapons at him and asking whose side he’s on, Shuu’s in the messiest mess yet. And frankly, that’s the best way for this series to end: never taking itself too seriously and gleefully embracing the mess.
