Araragi’s meeting with the First One is cordial, but becomes increasingly tense when he learns what his predecessor wants: for him to “break up” with Kiss-shot. Now that he’s back in the picture, he wants to go to her, make amends, and take his place by her side, while regaining the sword he “lent” her.
Araragi, believing this a legitimate parlay, almost takes a sip from a poisoned sports drink the First gave him, which is all Araragi needs to know: the First wants him out of the picture, one way or another. The negotiations are only a formality, and Araragi isn’t able to come up with any cinvincing benefits for the First to stand down and let him remain Shinobu’s minion.
Izuko arrives with
Gaen Episode to save Araragi, but negotiations are over: it will come down to a duel between Araragi and the First, with the specialists working out the details.
Araragi got nowhere, but when he returns to the shrine, he sees Shinobu sitting on a supine Kanbaru, telling her if she apologizes for what she said, she’ll be forgiven with no harm done. But Kanbaru is defiant, and she’ll repeat those words over and over until they stick: it’s up to Shinobu herself to face the First and settle things one way or another, not Isuko’s or Araragi’s or anyone else’s.
For much of the argument that ensues, Shinobu’s little hand tightens menacingly across Kanbaru’s head as she reproaches a lowly baby human for daring to say she knows the slightest thing about the situaion. She thinks Kanbaru is being silly; that nothing can be gained, only lost, by personally confronting her former master.
Furthermore, it’s an insult to her present master. Basically, Shinobu only wants one minion—Araragi—and will accept no arrangements in which she has two. It goes on like this for some time, but Kanbaru remains unblinking and forthright in her belief that Shinobu is wrong. It doesn’t matter how much fancy archaic terminology she uses or excuses she offers, Kanbaru thinks she’s covering for her fear of what facing the First will affect her.
But Kanbaru is able to wear down Shinobu because she can relate to the First as the “second choice”, because she herself wasn’t Araragi’s, Senjougahara was. Shinobu rejects her comparisons with human relationships, but runs out of ammo when Kanbaru tells her every possibility she can think of is preferable to doing and saying nothing, even if she or the first are killed in the process…or even if she ends up choosing the First over the Second. The ball is in her court.
It isn’t that the duel between the First and Second isn’t still on—it is, and it will take place in the school courtyard—but when Shinobu eventually gets over the fact she soundly lost an argument to a girl nearly five centuries younger than her, she may be able to stop the boys from fighting over her. Note that if you strip away all the vampire stuff, this is about a pushy, needy old ex-boyfriend wanting to get back with his girl, but the girl having moved on with a new man.
Meanwhile, Kanbaru continues to lie on the ground where Shinobu left her, with a slight cut on her head from where she squeezed her, and Araragi delivers her BL novels and bra. Kanbaru, not unreasonably wants to be rewarded by her upperclassman for the service she provided for Araragi—doing what he probably couldn’t have done (again, because he’s not the “un-chosen one” the way she and the First are). Whether it’s by him feeding her as she reads, or him putting her bra on while she reads, it’s all good for her.
