Ep. 9: Mizuki dan Eiji menyelidiki Menara Barat yang memanipulasi gravitasi serta hilangnya Ayaka yang misterius.

Sandman's castle is being repaired. Mizuki reminisces about Ayaka, who was her best friend. Eiji has recovered from the injuries he sustained fighting off the Zeravire, but he runs off to Mizuki's room after the maids attempt to give him a physical. Mizuki leads Eiji to the West Tower and tells Eiji about Ayaka's stay in the castle. Ayaka trained too hard and became bedridden, as this was when she disappeared after a mysterious accident. Inside the West Tower they find a large monument, similar to the one where the Gravion was built. Mizuki accesses the computer system and discovers the West Tower manipulates gravity, just like the Gravion. Mizuki conjectures that Sandman has unlocked the secrets behind gravity to be able to build the Gravion. Mizuki finds the security footage from when Ayaka disappeared. The video just shows her disappearing off screen with no explanation. Suddenly the monument lights up, and the West Tower starts shaking. Mizuki falls down the West Tower, and has a vision of Ayaka. Eiji manages to catch her, but he falls after her. Eiji has a flashback of being with his sister, and she tells him that they will meet again one day, as long as he keeps fighting Gravion. Eiji wakes up in Luna's arms. The rest of the team has found Eiji and Mizuki in the West Tower, as they had not fallen at all, instead they just passed out. Sandman makes an order to modify Gravion to be able to be piloted unmanned. (Source: Wikipedia)
