Little translation help

Wondering what this small paragraph means?

己の強さのみを追求し、ありとあらゆる剣技を收めた騎士。その実力は計りしれず低俗な悪魔や魔獣は手を出さない程。

己の強さのみを追求し、ありとあらゆる剣技を收めた騎士。その実力は計りしれず低俗な悪魔や魔獣は手を出さない程。

A knight who pursues only their own strength, and has learned all manners of swordplay. True strength is such that no demon or beast would dare raise a hand against them.

I'm not Japanese though, so take it with a grain of salt. Also, there is some context missing as to exactly how the sentence is trying to come across. I translated like a description of a class in a game or something.

その実力は計りしれず低俗な悪魔や魔獣は手を出さない程。
True strength is immeasurable such that no low-grade demon or beast would dare raise a hand against him.

Add a few words..., however I'm not good at English.(x_x;

Can someone translate this sentence?

これは きむらさんの なまえ ですか.
I know it means something like "Is this the name of Mr.Kimura?",but i don't quite understand it.

Yes, that's just "Is this the name of Kimura-san?".

For example,
someone find the word "Hanako" on the ring or something,
then he ask "これは きむらさんの なまえ ですか"?
Ms.Kimura will answer "Yes, my name is Kimura Hanako".
