Don't take that site too seriously with meanings. It's pretty inaccurate as far as I can tell. It's useful for some things, but I NEVER go there for meanings.
Kira's actual meaning:
KIRA f Russian
Russian form of
KYRA -->
KYRA f English
Pronounced: KIE-ra
Feminine form of
CYRUS -->
CYRUS m English, Biblical
Pronounced: SIE-rus
From
Kyros, the Greek form of the Persian name Kûrush, which may mean "far sighted" or may be related to the Persian word khur "sun". The name is sometimes associated with Greek kyrios "lord". This was the name of several kings of Persia, including
Cyrus the Great, who conquered Babylon. He is famous in the Old Testament for freeing the captive Jews and allowing them to return to
Israel.
So,
Kira means either "far sighted", "sun", or "lord".
