You know, i had this theory that the Final Boss Might be Roko. Like sure the Queltz seem to be the Main Big Bad Evil guy. But outside of what the Tailed rat said. We really don't know anything about their plan for the eye. Granted i might be reading into this. But we just don't know enough about ghost in this universe. Let alone one that is a Perfect ghost like roko. As the only other ghostly figure we met was the God of death. And i don't think their reapers are that Talkative.
Anyway regardless Roko is missing with a single egg. Begs the question who would steal the egg? And what exactly is Roko doing outside of making himself the number 1 suspect?
Ps, i don't really mind Roko eating their souls or Mana. Whatever you want to call it. Everyone got to eat something. Its just brand has a soft spot for the birds. Why, i don't really know, maybe he really wish he could fly in his old body. Or maybe it is out of spite for the Queltz due to them being their ehh slaves/servants. Regardless thou considering brand is probity still mad at roko. Seems a bit inconsideration to even consider eating their young. Which if you recall page 416, Roko Defiantly was like, i want me some Baby Back Souls.
Pure supposition but Vetra-jou strikes me as a likely candidate for the final boss. Though it could be her, the Puppetmancer (whoever he is), or Suzokon-kyo (but I repeat myself). But Roko? Roko's trying his best to be helpful and he's saved their butts more than once. He just has compulsions he can't help.
I can see him becoming a monster, though, if he eats too much mana too quickly. Think
Murder Mystery from Mystery Ben's Mystery Skulls music video series (which also features a good-aligned kitsune named, well, Mystery).
SPOILER: Mystery apparently dies defending Vivi, but right before his death, he's possessed by the Big Bad of the series, the powerful demon Reverb. And that transforms him from a kitsune to a straight up tartarigami, or Curse God. Thus, Murder Mystery. The gang is in serious trouble.Try to imagine Roko looking like
THIS.From what Suzocon was saying, at least, "mana" seems not to equate to "soul" but to "life force." In this universe, one's life force, once separated from their bodies, can act like a mindless ghoul; it seeks out other sources of life force to keep itself going, just like predators eating prey. They start with plants, but eventually can become real threats if not cleaned up by the Reapers. Roko isn't just a puddle of mana running on automatic, though. He's an actual
yūrei (ghost) which is what caught Suzocon's attention.
The eggs are alive, so they have life force. Roko can sense that. He don't care where he gets it from, he just needs it to exist, as much as we need food. Headcanon: He needs a LOT of it to sustain himself as a
yūrei rather than just a mindless manabeast. But if he gets too much at once... Katie bar the door.
