- Yui Koike went to high school together alongside Engine Sentai Go-Onger cast member Rina Aizawa. Inspired by Aizawa's success as Saki Rouyama, Koike auditioned for Samurai Sentai Shinkenger, but wasn't casted until she landed her role in Gokaiger. At the beginning of filming, she was initially hesitant since her face does not display the appearance of a pirate. Her favorite episode was Ep. 41: Something I Don't Want to Lose, since it depicted Ahim's tragic past of losing her home planet to the Zangyack.
