Kiri probably offered Jana a truce at one point or another. Dunno about Jana's response.
Kiri and Ether prolly got along fairly well.
Kiri may or may not have interacted with Ethon a bit. Dunno.
Kiri was probably somewhat nice to Sabrina. Best to be nice to the potential hunter. Best case, friends happen, worst case, they don't try killing you.
Kiri probably pointedly ignored David's existence. People who use force from the getgo to get their points across aren't actually people in his head. Always use words first. If words fail, Theeeeen you get to melt them.
Kiri probably attempted to interact with James. Dunno how this would go, depends on if James stopped being racist.
Kiri probably interacted with both Wiles and Plutarch or however you spell that. Probably more with Plutarch than Wiles due to Plutarch being more interesting.
Kiri probably interacted a small amount with the Tengu. Likely not too much. He's met Tengu before and these ones aren't super interesting yet.
Kiri probably interacted with Tori, although Tori probably continued hating him. Like he does with everyone else~
Kiri probably at a minimum introduced himself to Darran.
Kiri probably attempted to interact with Dimetri, that may or may not have gone well depending on if Dimetri wanted to be civil or not.
Kiri would have interacted with the various vamps at least a few times. Probably a bit more with Alice due to interesting background/behaviors.
Kiri would have interacted someone with Kumo, depending on if Kumo actually improved from his state of mental fugglery or not, he would continue or start losing interest.
Kiri would have interacted somewhat with Tessa, probably not much though.
Kiri would have probably interacted with Nina a decent amount upon finding out she's Tessa's sister. Mostly to attempt to figure out why the crap Tessa is supposed to be kept in the dark but maybe a bit more interaction.
Kiri might have interacted with Yuri a tad. Not too much though, he dislikes super formal people. Gets annoying.
Kiri probably interacted with Larissa a decent amount.
Kiri would have interacted with Alaric, interesting person.
Kiri would have interacted with Corentine, became interesting after necklace was removed.
Kiri probably talked to Akane at least once. Not much interest though.
I'm probably missing some people.
Edited in Akane.
