Celestial of Faith
The city was in peril, the unexpected attack has left thousands of casualties. Screams can be heard from afar, surviving victims wouldn't dare try attack the celestials and instead prioritise escaping with their lives; for most, however, that was impossible. Amongst the survivors was Aki, who with his tactical thinking knew that there was no chance of survival without their close ally - Demon Lord Diablo. With this thought in mind, he makes his way to the subterranean summoning chambers located beneath the Supreme Archdemon palace.
"HAHAHA!" Nebula laughs to her achievement, "DID YOU SEE THAT TONE!? I KILLED HIM!"
"THAT'S SO UNFAIR!" Tone responds, at the same volume as Nebula, "I ONLY GOT THE WIFE AND KID!"
"You snooze, you lose I guess!" Nebula pokes at Tone.
"Don't even start-"
"SHUT UP!" Kin shouts, interrupting Tone, visibly annoyed. "There's more of them. It's my turn."
Kin approaches the 24 remaining Supreme Archdemons, who have realised that their commander and friend, Kuragari, was killed.
"DARK DEFENCE ULTIMATUM!" They yelled, preparing for an attack from the celestials. This spell required assistance from every one of them; it created a 24-layer, magic resistant barrier with each layer being stronger than the previous the further inward you get. The Supreme Archdemons charged up a giant combined attack using all of their strength.
"THAT'S MORE LIKE IT!" Nebula shouts, riled up. "FINALLY, SOME ACTUAL STRENGTH!"
"I CAN'T WAIT TO SEE THEM FAIL, HAHAHA" Tone adds, ignorantly.
"You are both FOOLISH! Can't you see that this attack will kill us all if it makes contact?" Kin replies in frustration at her comrades' incompetence.
"If you're so worried about it, then just use your Holy Skill." Tone suggests, less riled up than before.
"That's exactly what I'll do." Kin responds, with confidence for once
"DEMONIC PROWESS!" The Supreme Archdemons shout as they launch their beaming attack at the celestials. The unified strength of the soldiers makes this an S+ Attack, stronger than the Archdemon's themselves are.
"Holy Skill: REBOUND!" Kin yelled, as she materialises a giant sword, seemingly from thin air. She swung the sword at the beam itself, barely making contact with it; even so, it is sent right back towards the Soldiers at twice the speed. Before they could fully react, the beam crashed through each and every layer of the Dark Defence Ultimatum. With a very short time to react, the Supreme Archdemons dived out of the way as swiftly as possible but even so, the 12 soldiers closest to the shield were demolished by the blast, leaving only half of them with their lives.
"Tch, alright, Tone, they're yours." Kin spitefully says, disappointed in herself for not being able to kill them all so easily.
"That's just what I'd been waiting for." Tone responds, smirking at the noticeably jealous Nebula.
…
After helping her family escape, Kasumi went to find Shinji and sure enough she found him all alone in the wreckage of his home. "Shinji... What happened?"
Shinji had been frozen, staring at his parents' ashes up until that point but seeing Kasumi brought him out of his grievous trance. A tear slowly ran down his eye, "They're dead."
Kasumi understood him well, but couldn't muster up anything to say.
"It was them, wasn't it?" Shinji spoke, as emotionlessly as he did when he gained immortality, "Those... Humans. Those... Celestial mages?"
"The Celestial of Faith, the Celestial of Patience and the Celestial of Pacifism" Kasumi told him, feeling as though she needed to.
"I see, take me to them." Shinji spoke, showing a true demonic expression for the first time in his life.
Shinji stared at Kasumi with his dead eyes. Reluctantly, she sprouts her wings and has him follow her. It's not long before Nebula senses the presence of a strong demon like Kasumi and her interest is peaked, especially since she can tell that there's a much weaker demon alongside her. Nebula rushes over to the two of them to meet them halfway, continuing to use light magic to fly, leaving Kin to follow Tone in chasing the Supreme Archdemons.
"Shinji... you know you can't beat them." Kasumi said, ineffectively trying to change the will of an immortal.
"There is nothing one cannot do when he lives forever" He replies, emotionlessly.
"You've come to sacrifice the weakling to the gracious celestial of pacifism, I hope." Nebula speaks, mockingly of Kasumi. "Or is it that you actually think you stand a chance against me? No, it can't be, not even a monster like you would be stupid enough to think that."
"Keep your ego to yourself," Kasumi says, sternly, "He's the one who will fight and kill you."
"HIM!?" Nebula exclaims, amused at the thought. "THE WEAKLING!?
Shinji's dead expression had drastically changed to a piercing glare; his seriousness was undoubtable. Nebula noticed this and her interest had peaked.
"I'LL BE SURE TO MAKE YOUR DEATH A PAINFUL ONE, WEAKLING!"
