I think sora knew partially that queem was somehow alive and tried to induce Tokio to become her clone (doing the whole bestowing and forcible injecting thing) but didn't know azuma was the clone of queem. So it's like both of them being induced to become fake choujin X because the last 2 refused to die and continued their proxy war into the succeeding generations.
Reread the first 2 chapters to check, and Ely never got an injection. I think she might the true choujin x for this generation, I hope the future vision tokio had wasn't them teaming up to defeat/save a triple choujin x Ely
People can become choujin naturally, zora juice is just the only way to force it
Ely probably already become a choujin a while back but her power being absorption made it so nothing really happened
Or maybe burning alive in the plane made her a choujin in that moment 🤷♂️
Didnt zora get queems power the same way?
Anyway wonder if zora juice had any impact on azuma or if he just turned after being hacked apart because his already existing power awakened
Him being cartoonishly strong from the start makes me think the later
