This is not any of the pink Sentai (none of them has tits that bi a helmet like that) and the katakana text under the logo is also nonsense. Most generous interpretation is this is just a random cosplayer with a custom armor, because of the nonsense text I'd say this is AI but it's probably older than that, just a good old 'shop.

Also bottom left picture the pink "ponytail" or cloth thing is attached to the helmet, bottom right picture it's still attached to his hair/neck.
