#11: [天竜の理論] Tenryuu’s Theories

From time to time, Shiro goes to the secret library to study ancient magic and prepares himself for three things; Hell's tournament of kings, the school's Six-school tournament, and for 001's raid. King helps him fill his cursed eyes with ancient magic.

At the A-DL HQ, Shiro attends as Tenryuu and does his solo missions, when his squadron signs into the log, he is notified by Noro and retreats almost instantly. Squadron 7, led by Tenryuu, they do their missions and completes them without losing a single life, they went home after they did their job. Shiro [Tenryuu], on the other hand, still has to turn in the reports from their missions to Noro before going home. Once he got home, he took a bath and teleported to Hell.

"Kid, you've been quite jumpy today, anything wrong?" King [Lucifer] said "It's just, there is something I need to check real quick, it's about ghouls"

Shiro quickly grabs the ghoul corpse he was experimenting on and melted its bones, taking its veins before the procedure. Once melted, Shiro places demon steel into the mix and continued melting everything, once everything has completely melted, he cast it into a bard and let it dry.

The veins however is transplanted to both of his arms, hoping to get the same abilities as them once the procedure is done. When the ghoul corpse has dome cooling, he took all of his Legions and fused them to the cooled corpse. Once fused, Shiro started to form the shape of the cooled Corpse into and sword, when finished, he named it "[流血] Ryuuketsu". He swung the blade and gave it purpose "To fool those around him with the blade's deceit and kill them with no mercy" He wrote to the blade as if it is a curse.

The next day, Shiro was casually going to classes as per schedule but Noro, who is at HQ, called him and told him that there was a ghoul attack.

Shiro rushed to the HQ by teleporting to Noro's office and switched to his Tenryuu persona. Once he's out, he saw a horde of ghouls and 001 with them. The members of A-DL were fighting desperately with their Legions, and squadron 7 was an exemption, they were working with complete cooperation and proficiency, Shiro [Tenryuu] however, is a tad bit different.

He wounded his hands before holding [Ryuuketsu] and he let his blood drop to the ground. He finishes them with Ryuuketsu in one clean swipe, Noro thinks that the sword [Akatsuki] doesn't look like that and so he asked. "It's just I was thinking of fusing all of my Legions and made one invoker out of it" he replied. Shiro whispered something in Noro's ear and nodded his head. "ALL UNITS FALL BACK!" he ordered. When all squadrons have retreated, Shiro took the battlefield alone and touched the ground, he activated his curse and said "Blood of the fallen" spikes made from blood soon rose and pierced every ghoul it touched, 001 got away from the perimeter as it all happened.

Noro and the others got shocked at what happened, they're still processing what happened. "A human being cannot do that right?" one said "Demons may have those kinds of skill set but not human" another stated.

"I merely imagined the dark attribute being connected to morbid topics such as blood, bones, and torture, there is nothing more to it than that. Humans are created with a free imagination, if humans are to rely on basic things, there wouldn't be technology" he argued.

Noro thought that it was a good alibi and forgave it. The other members thought that it might be possible to use it like that too, though they are having difficulties imagining how it should look. They surfed the internet about an article similar to Tenryuu's claims and found one with the exact concept, the author's name: [Tenryuu]

A few weeks later, Tenryuu's mask had been broken, but luckily, there are no one to see his face, he used demon steel to instantly craft a helmet that can be broken down and regenerate itself as one or multiple things based on the user's imagination. Shiro made a suit out of it and called it [Particle]

[Particle steel theory] is a theory that states; steel that can be restored to its former shape by infusing mana in it, and its founder: [Tenryuu] the same person that found the [Blood manipulation theory]

Tenryuu's new suit was noticed by everyone, even the barista, Miss Sekaijuu Izanami noticed. "That's [Particle steel] right?" she asked "You read?" "Yes, I thought that I was a good theory, especially the [To be broken and restored at will] part" she said.

Tenryuu smiled from his helmet and said "I think mom will be pleased to see you" he said in a different tone "Kuro?" she said and froze "I thought so, if I copied his voice, it would ring to you" he said "Wha-What did you do?" she asked "I should be asking that very question… Mom" he said as he took his helmet off and revealed his face

"...Shiro?..."
