Hmmm... I think this familial love theme could work. It would call for a grownup battle such as the Unohana-Kenpachi duel... since Byakuya is kinda known for being an idiot when it comes to heart matters, and PePe probably having his own cuppa. It would be a nice way to get to know more about Hisana as well, but I guess it would depend a bit on PePe's abilities.

I dunno, it might just be a silly coincidence, but it feels a bit that the Sternritter abilities are themed. It's almost as if Kubo is referring to that the Sternritter work like a mammalian brain, with the Sternritter' fighting abilities based on neuronal projections in the central nervous system (Äs Nödt's fear ability, Gremmy's imagination ability, PePe's love ability, etc). Perhaps that is why it feels the Sternritters are so twisted and different. If only Kurotsuchi could at least inhibit Yhwach's signaling... ;)
