Kousaka Renn (香坂 連 Kōsaka Ren?) is an minor character in Pretty Cure RPM. He is currently as Go-On Blue (ゴーオンブルー Gōon Burū?). Nicknamed the "Cyclopedia" for his attention to the smallest detail, is a former bus driver who tends to be somewhat talkative.
Because of his doting personality and cooking expertise, he has been referred to as the Go-Ongers' "mother" (オカン okan?) by the other Go-Ongers and even his own Engine partner, Engine Bus-on; he takes no offense to and even revels in the reference. The son of a family that runs a beach-side inn, Renn, as a young boy, prayed and offered omelets every day to a guardian statue in the eventually futile hope that his sickly mother would recover. The guardian statue turned out to be the sealed form of the Arerunbra Uzumaquixote, which Renn learned only after Air Pollution Minister Kitaneidas and Water Pollution Minister Kegalesia tried to claim it. Renn carries a small memo notebook, which is the source of his massive knowledge; in it, he jots down notes about and draws doodles of the enemies the team faces, even in the middle of a fight. Not only is Renn the "mother" of the team, but he is also the chief technician; he made modifications to the Engines so they could come together in the Engine-O G6 and Engine-O G9 formations, developed the Kyuyu Soul and the Double Engine Soul Kankanbar, and assisted the Go-on Wings in fine-tuning the Armored Wheel GoRoader GT. After the final battle, Renn becomes Esumi Sosuke's mechanic in the go-kart racing circuit.
As Go-on Blue, Renn's physical strength is magnified. After transforming into Go-on Blue, Renn says, "Just Correct!! Go-on Blue" (ズバリ正解！！ゴーオンブルー Zubari Seikai!! Gōon Burū?). With the Mantan Gun in Rod Mode, he can perform the Go-on Drift (ゴーオンドリフト Gōon Dorifuto?). With the Mantan Gun in Gun Mode he can perform the Sniper Shoot (スナイパーシュート Sunaipā Shūto?). With the Garage Launcher (ガレージランチャー Garēji Ranchā?) he can perform Launcher Starter (ランチャースターター Ranchā Sutātā?) and Jumping Attack (ジャンピングアタック Janpingu Atakku?).
Renn, along with the Go-Ongers and Go-On Wings, which there are walking in the big smokes. Haruka Minako was interupted if she said:
- "The Rangers, the Sentai Rangers! We want to fighting each! I know that who has an identity if there are removing the Helmets!."

Meanwhile, the Enaji twins were faced by the Go-On Wings by each. Kinri was fight with Hiroto, while Ginri was fight with Miu. But Renn was fight with Nami. Nami removes Renn's helmet while fighting and she is very worried. She stops the fight and it was revealed that Nami's cousin is Renn. Now, the rangers are still in friends.
