Setsuna's: Easily my favourite of the redemption stories, because of how well it was told. I liked how it started off as her being raised in a cult, and what started out as an attempt destroy the Fresh team, through those attempts you understood her character, and you sympathized with her, and wanted her to become redeemed by the end. Which ended up happened.

Ellen's: Not as good as Setsuna's, but I liked it overall. I do like how it was her lingering jealously over Hummy is what lead her to be brainwashed into joining up with Mephisto's gang, and in my opinion she was honestly the most competent member, of the bunch. Eventually coming to realize that she never wanted to destroy that friendship, and did try to become a better person afterwards. Plus...she was funny, pre-redemption or post redemption.

Towa: This is one I also think isn't as good as Setuna's, but I do like the set up of how she was practically brain washed as a CHILD into thinking she was Dyspear's daughter. That some tragic and dark stuff. Most of her arc is mostly just her learning to be more self reliant, as they recognize that what she was doing wasn't out of her own volition. Although Setsuna is my favorite mid-season/sixth ranger cure, I will say in terms of debut battles, Towa definitely wins in that reguard.

Ruru: This one honestly reminded me a lot of Chase's in Drive, basically a robot working for the villains, but learns to understand human emotions. Its similar, but not to a point of being a cheap carbon copy.
