Ayane cannot have all her Ghosts at the same time nor switch Ghosts with Awaki, because that's not how Ghosts work.
The only version of Ayane that can avoid losing the fight right at the start when a bloodlusted Awaki teleports her body underground or teleports a random object into her brain is the one with Chaos God Nyarlathotep that could achieve a mutual kill by immediately crushing Awaki's body. Given Awaki is faster in the draw with her power, it's not a garanteed success, but it's her best chance. Du-Du is garbage tier, she's pretty unlikely to touch Awaki with Aeshuma or Emperor Snake Basilisk, Hizama won't let her finish the fight in one blow at the start even if she manages to take Awaki by surprise with the portals and the air manipulation ghost's best attack (the atmosphere thinning trick) is not quick enough to prevent Awaki from retaliating.
In terms of intelligence, which is not going to matter in this fight at all, I honestly don't consider Ayane's feats above what a decent Level 3 or Level 4 esper can do.
"Ayane can switch ghosts" erased.
What do you want me to do to change the thread?
