Blake hurriedly ran as fast as possible with Eric, Chris, and Erika where the Priests were located, as they were closer to the frontlines where Blake assumed his father could be. Of course, he let go of four Fenrir and three Orcus accompanied by three Spores to go look for his father.
The war was intense and there were many corpses of both demons and humans lying around everywhere, although Blake was worried about his father and his close comrades in the priest's group, he was also considering the insane amount of EXP he could get from this war.
He decided to immediately send several of his other Spirit Beasts to slay the demons within his surroundings, and while doing so, he finally reached the priests.
While getting here, he had felt two powerful presences. One of them was when Elizabeth awakened her Spirit's Transformation Ability, a powerful holy and divine energy that seemed all-encompassing. And then the latter, which had just happened in a big explosion of demonic energy, which came directly from Erdrich, who was right in front of him.
Blake told his friends to quickly slay the demons that were coming from the woods incessantly, all while he confronted Erdrich and protected Elizabeth and Jack barely by erecting a barrier using the Tier 1 Earth Magic Spell [Earth Wall], which crumbled seconds after taking the damage from the overflowing demonic energy coming from Erdrich, allowing the half-demon boy to see Elizabeth and Jack in the floor, and assuming the worst, that they were both dead by his own powers.
"What's gotten into you, Erdrich?"
"B-Blank…?!" Muttered Erdrich in between his terrifying demonic voice.
Blake knew very well what was happening to him. Erika, Eric, and Chris were confused about what was happening, but as they were busy dealing with the incoming Imps and joining with everybody else in the chaos of the battle, they were unable to come and ask Blake as easily.
"(Are his demon powers taking over him? What provoked this? Hm… Well, I don't have time to find out…)" Thought Blake, immediately being confronted by a storm of Demon Flames reaching him in an instant.
The blue demon flames reached him in an instant, as he swung his Spear, Gluttony, and quickly pierced through the spiraling vortex of demonic flames, destroying it in midair!
Erdrich's eyes, now fully demonic, opened wide in slight awe. However, his demonic nature, now fully controlling his body, was sharp and merciless, quickly seeing Blake as his new target. Blake was constantly thinking what was happening to him, and the most obvious answer could be that his demon and human part had yet to fully unify, creating an alter-ego out of Erdrich's own demonic power.
Something, perhaps emotional damage, weakened his human will, enough for the demon to take over.
"I will have to beat some sense into you, friend. I don't have all the time of the world, there's my father and a lot of EXP waiting for me." Said Blake. For a slight second as he spoke, Erdrich once more regained his human voice.
"K-Kill me…!" He cried. "I… I killed Elizabeth and Jack… I… am a monster!"
Blake raised an eyebrow as he heard the boy's cry.
"What? I have yet to even use your powers. You're too useful to be disposed of, Erdrich." He said. "And no, you didn't killed them. I protected them before you could harm them…" Blake pointed at Elizabeth and Jack in the floor.
Jack was being healed by a strange Ki Aura that Blake left over him, this was an invention of him that merged Ki and Mana named Healing Ki Bandages, they were bandages made out of materialized Ki and Mana loaded with healing spells effects and his [First Aid Lv2] Skill, they were barely keeping Jack and Elizabeth alive for now.
"I-I didn't…? I… I…! Nnnggh..! AAAGGH…! T-The demon… I have a demon inside… Blank…! Kill me…!
I am too dangerous! AKH… AAAAGGGH…!"
Erdrich began to cry in between groans, within his own mind, he was fighting against a monstrous entity dwelling deep within his subconscious, the alter-ego that encompassed his demon side. Blake couldn't help but find him a weakling for being taken over by such a feeble little ego, which he would be able to easily devour with his sheer willpower.
However, it wasn't as if he could expect so much from an unexperienced child.
"I won't kill you, Erdrich." Sighed Blake.
He quickly flew towards Erdrich by using the [Gust] Tier 1 Wind Attribute Spell to help himself fly at a fast speed through the air, and quickly pointed his spear towards Erdrich's chest!
"Blood Spear Arts: Thousand Blood Needles."
His spear suddenly moved at an incredible, superhuman speed, creating mirages out of Blood Ki Aura, which began to materialize into hundreds of spear-sized needles that started to pierce through Erdrich's chest! The boy had grown up to four times his original size, resembling a fully grown man-demon by now, the attacks covered his entire chest despite such an enormous body!
CLASH! CLASH! CLASH! CLASH! CLASH! CLASH!
The Thousand Blood Needles was a Technique that caused a great amount of pain and suffering, but dealt little damage in actuality, it was an ideal technique to use against someone Blake didn't wanted to kill but make suffer enough to snap out of his insanity!
The intensity of Blake's attacks threw the man-demon into the ground, making him roll through the floor as he vomited a mouthful of blood.
"Ungh… Grrrr… GRAAAH!"
However, Erdrich quickly got back up like nobody's business, his resiliency and stamina had multiplied several times the moment he became fully red-skinned, and these new black-colored runic tattoos were also enhancing his strength and stamina even further! He ran straight towards Blake, clashing against his spear with his giant claws!
Blake couldn't help but smile as he felt the exhilaration of a challenge… the power that Erdrich was emanating was truly surprising to him! This also meant that the half-demon boy was truly a promising subject, this only made Blake want him to come back to his senses even more.
"Heh, you're not half-bad…!" Said Blake with a defying smile.
