Without seeing the Kanji, I cannot definitively translate the 'ku' you are referring to. 'Ku' can mean several things, including 'nine,' 'ward,' 'section,' and 'pain.'
"Ku gatsu" is a Japanese word and in English it means "September"
テクニック (lit. te ku NI ku).
The word for "Noir" (I'm guessing you mean the color black by that) in Japanese is Kuroi. くろい ku ro i
テクノ (te ku no)
If you mean the word for it, it's already answered in you other question. テクノ ( te ku no )
クイン /ku in/ would be the Japanese term for that name.
If the word is of Japanese origin, it is spelled. あ (a) く (ku) り (ri). Or, if the word's not of Japanese origin (which I doubt) it would be ア (a) ク (ku) り (ri). Copy that as best as you can.
"Ranmyaku"ron-mya-ku
you probably mean haiku, a Japanese form of poetry?
kikei or furi-ku
至福 /shi fu ku/ is Japanese equivalent of the word. If you mean it as the Christian rank or title, 陛下 /hei ka/ (Majesty) and 閣下 /kakka/ (Excellency) could be used for it in Japanese.
"Ku" in Japanese can have different meanings depending on the context. It can mean "nine" when counting, "empty" or "void" when used in Buddhist terminology, or be part of words like "kumo" which means "cloud" or "iku" which means "to go."
