User blog comment:MysteriousGalaxy/(WARNING: SPOILERS) Possible identity of Hugtto Precure's 4th Cure/@comment-2056915-20180204003926

It seems to be a mistake. There are leaks about "6th ranger" -- you can see it around the wiki if you enjoy spoilers and as the leak revealed, there's no Cure Cry (as well as in the original Japanese article).
