At this rate Yonehara and Ashigara are gonna be the parents of all the reincarnated Abyssals. I'd like to see a story involving the couple dealing with their kids growing up. One could even be Yonehara being in a Father of the Bride scenario as he deals with having to let go of his Rei to be wed.
A bit of an explanation on why Kit Kats (and why it doesn't surprise me that she'd buy this).
When pronounced in Japanese, Kit Kats is pronounced Kitto Katsu, which are homophones of the Japanese words for kitto (likely) and katsu (victory). This is also why exam students stock up on kit kats; they're seen as lucky charms for exams.
It's also no surprise why the victory (katsu) obsessed Ashigara would love this type of snack.
With the amount of energy Hungry Wolf has, it's honestly probably one followed by the other. Not necessarily in the order you would think. What that means when it's Ashigara involved I will let you imagine for yourself
