Nibbles? More like, a breeing pedigree... xD

As for getting along... I mean, if you look at the characters in the Overlord series, many of them squabble quite a lot. In particlar, Sebas and Demiurge, Shalltear and Aura, Shalltear and Albedo, Albedo and pretty much any other female(s), most of the Pleiades are jealous of Narberal. That said, they might not outright hate or detest each other, but they certainly don't always get along. Ashara is polite and gracious, so she would never stoop to outright disliking or scorning someone - less they somehow upset her nigh-infinite patience - but that doesn't mean she 'gets along' with everyone. :P
After all, she is very honest... Very, very honest, and - as per her creator - has preferences and opinions of others.

"Ah, Director Graft, good morning~ *bow* My, you are looking as grotesque as always, I shall pray for your body's swift recovery."

"Oh, milady Chuunithulu, a good evening to you. Oh dear, the stench of tobacco is really thick around you this eve, a lady should take a bath every once in a while. *friendly smile*"

You get the idea. :3
