As she and Bell take turns keeping watch, Ryuu begins to experience flashbacks to when she met Alise and was part of Astraea Familia. It’s a reminder of all the people she’s lost, but also a rallying point for her: she’s going to make sure Bell survives this, even if it costs her her life. It very nearly does too soon when three beasts attack, but Bell wakes up in time to kill the one Ryuu isn’t able to.
Meanwhile, much further up, both Mikoto and Haruhime announce that not only are they not dead, but their spells give their comrades the opportunity and power boost they need to finish of Amphisbaena. Mikoto demonstrates what a fool I was to think being underwater and surrounded by piranhas would be enough to do her in, by casting her biggest spell yet: Futsu no Mitama, which freezes the boss in place.
While it’s not clear how Haruhime survived the brunt of the boss’ breath attack, she’s able to dig deep and cast Uchide no Kozuchi. Ouka, who had used an ice ramp created with the last Welf’s magic sword to climb up into the ceiling of the chamber, brings his axes down on one of the boss’ heads and slices it clean off with Kokuu, while Aisha leaps right up to the remaining head’s mouth and unleashes a mega-Hell Kaios.
Cue victory fanfare…or rather a few blessed moments when the party is able to catch their breath. Aisha tends to Haruhime and Chigusa and Ouka tend to Mikoto, who are unable to walk. Then tremors begin, and the entire cavern threatens to collapse on top of them: the “coffin” from Cassandra’s premonition is still in play. Aisha and Daphne urge the party to flee up to the 24th floor like Turk and his team.
Cassandra, however figures out that “towards the life-giving sun” doesn’t mean a person or a place, but a cardinal direction: East, the direction of the sunrise. That happens to be through a recently opened tunnel down to the 26th floor. Daphne doesn’t believe Cassandra’s premonitions, but after Cassandra pleads with her and sheds tears, Daphne decides to believe Cassandra, the person.
Lili and Welf were already prepared to descend in order to locate Bell, so now everyone is in agreement. And with absolutely no time to spare, either, as the party witnesses what would have happened if they had gone the way of Turk & Co. The branches they were climbing collapsed, and then they were buried in stone, crystal, and plant debris.
It’s the rare instance where the 26th floor is a lot safer than the 25th, because it’s the place where they’re all still alive. They’ll have to keep descending quite a bit to get close to where Bell and Ryuu are. Perhaps they can meet in the middle? But I don’t want to forget what an impressive boss victory the party managed to pull off without Bell.
That win should give them confidence that, even in their weakened, battered state, as long as they stick together, they have a chance to find Bell and Ryuu and make it out of there.
