Magiknight94 is right and the current episode proves it.

(from 21:48 to 21:59)

It is clearly shown the Nekomata's Shuriken was caught by Nagi while two previously catured Shuriken became the Kakuranger and Hurricaneger Shuriken.

While he was wrong about the Shuriken only coming from when the giant Youkai are destroyed, he is right in that the Nin Shuriken don't come from the currently defeated Youkai.
