Rangercentral's profile on Shurikenger (http://supersentai.com/database/2002_hurricanger/rg-shurikenger.htm) states this:

"Truth has it that Shurikenger's ture identity was Shurikenger. Ten years ago he was a Kagura Asuka, a great ninja at Hayate Way, expected to become a Hurricanger, but he suddenly disappered. Gozen offered him the great power but it came with a sacrifice. He gave up his humanity and his face physically became the helmet"

Depending on which site posted it first, it's possible Rangercentral might've misheard it too.
