Who murdered Lingji.

So you might say obviously miyao killed Lingji as we all saw him do and and he was prophesized to do so, you might also say it's Toujirou who controlled Miyao's gauntlet to force him to kill her, both are true, but what if there was someone else behind the scenes?

Let's examine how exactly did Toujirou kill Lingji, Toujirou accessed Miyao's gauntlet and input exactly '5 keys', which caused Lingji's rejection shield to go down.

Even though Lingji had way more energy than Miyao and should have been able to keep up her shield

Why would Toujirou accessing Miyao's gauntlet cause Lingji's shield to turn off?

In the first MIYAO encounter he prophesizes Lingji's death and says it's because she won't be able to use her shield,

MIYAO says that her shield won't malfunction, meaning it will work as intended,So why did her shield break,?
The text says Toujirou has modified the Gauntlet's User Info. -> He changed the user of the gauntlet to someone other than Miyao.

When modifying the user info the text points out that he presses specifically '5 keys'. So he is changin the user of the gauntlet to someone with a 5 character name.

That gives us:     Fatma     Ishak     Naomi     Abdou     Lilja     Aysha     Andry     Naima

For characters with a 5 key name.

But that doesnt really make sense, Miyao is the strongest known gauntlet knight, so how could switching the user to anyone else make them any more effective against Lingji if he couldn't do it, especially since she had the golden gauntlet on.

Right after he switches the user info to someone, Lingji's shield turns off immediatly, that's because it was someone from her own kette who she had marked as a friendly unit, Aysha.

By transferring the control of the gauntlet from Miyao to Aysha he made Lingji's gauntlet recognize him as a friendly unit which caused her shield to go down even though she still had enough energy.

To pull that off Aysha would have to be in collusion with Toujirou and give him her gauntlet's master key.

In one of the scenes Toujirou talks with comrade 211 who is a member of his order of the Wisteria from the COU. Aside from being from the COU Aysha has a specific way she laughs which also fits the person speaking <Heheheh>

Almost all of her dialogue has her laughing like this

Aysha is part of Toujirou's chivalric order, she gave him the master key to her gauntlet in order to kill lingji by tricking her gauntlet into seeing miyao as a friendly target.
