Kasuyi係咪日本名?

Lately, it has been noticed that many young females have been coining strange, "English" forenames that may sound cute and Japanese. In the end, these so-called names become DQN names that make NO sense.
Such practice has been condemned by many.

No, it is NOT a valid name.
It doesn't make any sense.
BTW have you checked the spelling? The closest one is "Kasumi" but nothing else. See here:

(search for "かすみ")

Not every Japanse forename has a meaning. Some do; others don't. Some kanji forenames are coined by how it's being read (which may sound normal in Japanese, but makes no sense in Chinese).
