Does anyone know what to call the outdated, high form of language which will say for example "ならぬ" rather than "ならない" or more accurately "だめだ"?
Specifically, I would like to know if there is a name for the dialect used by Kuchiki Byakuya from the anime Bleach so that I can research it and learn it. Features that I have noticed about the way he speaks:
Particles like "は" or "を" are never dropped, and ～ている never becomes ～てる even in fast or casual speech (not that I've ever heard him speak casually).
～ない → ～ぬ.
ないだろう → なかろう.
そんなことはない → そんなことあるまい、そうはあるまい.
いい → よい.
お前、君 → 卿（けい）.
質問する → 問う.
I realize all of these things can be put down to simply old or overly formal language, but I want to be able to study it so as not to make non-native-speaker errors when writing (I intend to write a fictional character who uses such language). Thus, if anyone knows what to call this type of language (in Japanese), I would really like to know.
