NiSM0gaL, I wanted to help but are you sure u spelled correctly?
Its either not dictionary word (Casual/Made up word) or you have
gotten it wrongly. There's no word starting with Kuza. As for the
word Kin, it can means Gold or germs/bateria depending on the
kanji.
In japanese, Romanji only acts as a help for those who doesn't take
Jap as their 1st language and its for using in emails where some
people might not be able to decode the japanese they typed and act
as an extra for instant.
Usually, you have to see the kanji to under the message of the
word, especially when we don't know your conversation. For your
knowledge, Japanese is very often confused when words of similar
meaning/pronouc are usually wrongly. Therefore, the conversation is
the impt part to decode whatever the opposite is talking about.
