Pov General,
Dia couldn't regain her composure. Black, or rather Diablo, had asked her to take him as a servant.
Rouge: "Black, what the hell are you doing?"
Diablo: "It's simple. I accept Dia-sama as my mistress without having to lose to her. After all, you agreed on behalf of everyone, but I wanted to become her servant directly because I know she will accomplish great things, and I want to witness it from the front row."
Dia finally regained her composure and cautiously asked:
Dia: "And what if you attack me from behind?"
Diablo: "What? That would be the worst crime. I'd rather die than betray you."
Dia looked at him with suspicion.
Rouge: "You can trust him not to betray you. He's the most different from the seven of us. He doesn't seek power but rather to serve it."
Finally, Dia took a precaution by placing a crimson shield behind his back, just in case.
They all rose into the sky to begin the fight.
Dia directly used touki to increase his strength and fought with a naginata.
The yellow-haired one mocked him.
Jaune: "Are you sure it's not a little too big for you?"
Dia: "The bigger, the better."
Jaune was not prepared for such a suggestive answer and blushed, though it was nothing compared to Violet.
Blanc: "Are you trying to mentally attack us before we even start?"
Dia smiled at her.
Dia: "I just answered the question. It's not my fault if you have such a perverse mind."
This remark made veins pop out on Blanc's forehead.
Blanc: "Don't complain about what's going to happen to you [Hell King's Purge]!"
A huge flame headed toward Dia at an incredible speed.
She used her wings to increase her speed and dodge, but Red had already anticipated the movement and also used flames. Having no choice, Dia used a teleportation rune she had placed in advance to evade the attack.
Dia: 'They are at the ultimate class levels, and their coordination makes them dangerous.'
But Dia was not worried. She took the opportunity to dodge any attacks against her and analyze their abilities.
A sword aimed at Dia's back, but she dodged and used her naginata to try to wound the enemy. The attack was successful, but the target vanished as if it had never been there.
This shocked her a little, and then she went after Yellow to test her abilities.
Being too fast for her, Yellow could only use a shield to defend herself from the attacks. A dozen strikes landed on it but vanished.
Dia: 'I swear to Satan, she will become my Rook.'
The fight lasted more than an hour as Dia attacked them cautiously, avoiding unnecessary risks while dodging their attacks.
Individually, Dia can beat them easily but when they are together it is very hard to beat them. Dia has even doubts about the fact that she can beat all seven at the same time if their synchronization is the same.
Blanc: "[Annihilation]!"
This attack struck Dia's right flank, but instead of continuing to cause destruction, the wound disappeared as if nothing had happened.
Blanc: "Nani?"
Dia: "You're not the only ones with a good regeneration ability. Now, to congratulate you on your strength, I'll show you my true form."
An aura accumulated around Dia, so powerful that the others could do nothing against it.
Parts of her POD were emerging and destroying the surrounding landscape.
After this event, a form could be seen that, instead of being made of flesh and blood, was made of POD. She no longer controlled the power; she had become the power.
On her back, one could see 12 majestic wings of a deep black, in stark contrast to the crimson being to which they were connected.
A single move was all it took to defeat her four opponents without them even realizing their defeat.
