Based on the translation it means that Maya has no longer that ki she had been saving for two years long. I didn't get that Reiki part. Has she become the master of Reiki now, or has Reiki become the container of her soul?
From Aya's comments, it appears that the only way of transferring Maya's soul from Reiki back to her body is to use Souhaku's "Flaming Dragon Gate", which might be a bit difficult, since all that currently remains of Souhaku is his eyeball that was transplanted into Nagi Souichirou.
I found Mitsoumi's reaction to this revalation to be quite interesting -- he's obviously shaken. I wonder if it's due to the thought of Maya being clinically dead, or needing Souhaku's help in this circumstance, or his realization that he killed the one person who could save Maya.
^Well, technically if bringing Maya back meant that Souhaku had to use his "flaming Dragon Gate", than that means that there is a slight possibility that Nagi could summon that power sine he has the eye. Looking at the Maya and that mohawk haired guy fight it seems plausible imo, especially since the eye holds all the memories and special powers of the person.
^ It's possible, but I don't think that's going to happen. You know how many possessed people are going to be coming after the juken club just to make Souhaku awaken within Souichiro. Aya's is and will probably be more banged up by the time the fight between her and Hirohiko is done. Masataka and Bob both are going to have to hold on the rest of the team until the tournament is over.
hmm....so the key is the eye, yet souichiro has no control over it..
i wonder who things will turn out...
Actually, I'm really curious about the F-Group's next move. I have no clue how they're playing in this whole story.
