That turns out to be the best thing to happen, however, as they discover there that mana in the people of Rieze Maxia can be concentrated in the fossils of Spirits left on Elenpios, allowing a new form of the former Spirit to be created from it; a process called Origin, after the Prime Spirit of the same name. With new Spirits and a new sustainable supply of mana, Gin can be abandoned and everyone can get along, but Gaius refuses to believe that it will work out and Musee is just crazy, so they fight to end as the final bosses... and lose, but survive. Jude earns Gaius' respect and grudging willingness to at least try the new technology, and Milla wins Musee over by being kind since the poor girl just wants to be loved. But as the Shell dissolves to nothing, so does Maxwell, leaving nothing to hold up the system of Spirits, worlds and mana. So Milla decides to take his place, being born and bred for role even though it was a lie at first, while Musee sticks around with her and the party and Gaius return to Rieze Maxia to start working on preparations for the changes that will be coming.
