Hibiki and Tomoki participated in a joint battle to take over Stella Fortress which is held by the demons. Soon after the battle began, the troops supporting them fell into a trap and ignoring Hibiki's warnings, Tomoki invaded the fortress with his party, forcing Hibiki to do the same. The heroes were confronted by the demon army's general Io, but when Io used his powers to negate the Goddess' blessing, Tomoki decided to flee, realizing that he lost his immortality, forcing Hibiki's party to face the general by themselves. As Tomoki and the rest of the human forces retreated, the goddess discovered Makoto's location and forcibly teleported him into the battlefield, where he faced Sofia Bulger and Mitsurugi. Overpowered by the enemy, Hibiki's party also retreated, with one of their members, Navarre Polar, sacrificing herself to hold Io long for their escape. Devastated with her companion's death, Hibiki swores to become stronger, while Makoto who was in critical condition, was being treated by Mio and Tomoe. Back to the present, Makoto and Shiki finally arrive at their destination.
