The Holy Day celebrations start in No. 6, but the parasite bees start attacking everyone in sight. Meanwhile, Safu explains to Nezumi and Shion that No. 6 used her as a medium to access Elyurias. However, this was a trap by Elyurias, who has Nezumi destroy the main computer. However, Safu decides to stay behind. Nezumi and Shion try to escape, but Nezumi gets shot. Shion tries to drag him out, but gets shot in the chest and is killed, with Nezumi somehow getting them back to where Inukashi and Rikiga are waiting for them. However, devastated by Shion’s death, Nezumi refuses to leave, so Inukashi and Rikiga leave without him.
Meanwhile, all the bees that appeared from No. 6 citizens form into giant tornadoes when Elyurias, now fully freed, flies over and start destroying No. 6’s walls. Safu-Elyurias then returns to the facility, transforms into her true form (a giant glittering bee) and resurrects Shion.
Elyurias' true form: a giant bee. ZOMG RUN!
I guess that was an OK ending. Safu “lived” but only in the sense that she’s now Elyurias and is essentially immortal. Meanwhile, we never really learned what Elyurias was other than some sort of powerful being. Clearly the rulers of No. 6 were in way over their heads in trying to harness Elyurias’ power.
We also never got a complete description of what the bees were or what their purpose was, but as far as I could tell they were the doing of Elyurias. No. 6 was obviously aware of them, and perhaps even controlling them to some extent in their experiments to unleash Elyurias, but clearly the bees were used as a trap by Elyurias to punish No. 6 and pretty much wipe it out (though clearly, many people in the city still survived). Why the bees decided to attack some people and not others…I don’t really know.
In a sense, at the end, both Nezumi and Shion got their wishes. Elyurias brought the walls down, much like what Shion wanted, but No. 6 took a beating like what Nezumi wanted, and most likely most of the people in charge of it were wiped out by the bees, and even if they weren’t, they’re not going to be able to pull off the “we’re a great utopia!” thing anymore.
In the end, I suppose this was a decent ending to the series. I think it could have been better – I would have loved if Safu had survived as herself – but it certainly could have been worse too. I think the series as a whole was overall pretty good. I never necessarily like major plot points not entirely explained, like the bees, but I guess I can live with it. The series is probably good enough that I would recommend it to someone who is looking for something to watch, but I don’t know if I’d tell them to put down everything they’re currently watching to go watch this.
