Naiki Devi (12th c.) was the dowager queen of the Chaulukya (Solanki) dynasty of Gujarat — regent for her young son Mularaja II.
Featured in Prithviraja Vijaya and other contemporary chronicles.
Naiki does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Naiki reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
