Sorry if this is late.
You want to know Ahim is on the team? It's because she can go on a rampage and stay calm and strong and charming during it.
It was so refreshing to see another costume change fight. It was a nice call-back to past female Sentai heroines. Namely Momoranger, Gogglepink, and Pteraranger.
Ahim essentially dresses up as three things guys find sexy (it could have been four, but Luka already dressed up as a maid)
It was nice to give Ahim some development, and put her in the spotlight.
The episode catches the tone of Abaranger, given that the head writer of Gokaiger, Naruhisa Arakawa, wrote for Abaranger.
However, it would have been nice to see Yukito and Emiri more, and have them interact with the team.
I apologize for the quality of this review. Much like the quality of the AbarePink costume, it could be better.
