Fuu Hououji - Season 2

Season 2

While returning to Earth, Fuu acted rather normal, but she still harbored her grief within her heart. Eventually she revisited Tokyo Tower to reunite with Hikaru and Umi. After Hikaru declared that she wanted to return to Cephiro, they were brought there in an instant. The exception was that due to the lack of Pillar (Emeraude's position) the world was in crumbling state and three other worlds, Autozam, Chizeta, and Fahren, attempted to take over. The girls must defend Cephiro and look for a new Pillar before Cephiro crumbled.

In these series of events, Fuu helped in defending Cephiro. She also found out that Ferio was actually the little brother of Emeraude, making him Cephiro's Prince.

In the anime, more depth was given. When Hikaru's sword was broken thanks to Nova, Umi and Fuu was left to defend Cephiro on their own. Unfortunately, she was captured by the Fahren faction. In there, she struck a deal with its ruler Lady Aska into an archery match. If she wins, she's about to be freed but if she lost, they can do whatever they like. Fuu ended up winning and told Aska the truth of being the Pillar of Cephiro, which cast doubts on Aska's ambitions. Just then, Ferio busted in to save Fuu. However, her words eventually made Aska cancel her dream to take over Cephiro's Pillar position, knowing that she still love Fahren. Fuu later joined Hikaru and Umi to destroy the individual behind the chaos, Debonair. When they did, they returned to Earth, unable to come back to Cephiro anymore. However, they were satisfied that Cephiro returned to its peaceful state and beautiful form, and it was able to function on their own.
