Just as the day of the Eternal Paradise Cult's festival was approaching, one night, Doma was suddenly summoned to the Infinity Castle. "Eh? It's a summons from Lord Muzan!"
Doma finished the small snack in his hand in a few bites, smiled, and clapped his hands, adjusting the Founder's hat on his head. It had been less than a month since the last replacement blood battle. To be able to see Lord Muzan again so soon was truly a joyous occasion.
"But it's so strange. Did something happen?" Doma walked down the stairs with light and elegant steps, a brilliant smile on his face. "Could it be that Lord Muzan finally has an important mission for me? Ah, just thinking about it is wonderful!"
Over the years, apart from the routine task of collecting resources using the Eternal Paradise Cult, Doma had not received any other missions. Although slacking off was nice, it felt a bit like being ignored by his boss. "Mmm~ It couldn't be that an Upper Moon has died, right? Haha." Doma covered his lips and laughed without a care, then his eyebrows drooped, and he showed a worried expression. "If that's the case, it would be truly sad. We are all important comrades..."
The next moment, he sensed a familiar aura, and his rainbow eyes suddenly lit up. He flipped off the stairs, landed lightly on the wooden platform below, and looked up to see that pink figure.
"Good evening, Lord Akaza~" Doma approached him with an enthusiastic smile.
Akaza's expressionless face instantly furrowed, veins popped on his forehead, and his fists clenched tightly. I really... really want to smash this face in front of me.
Heaven knows what kind of days I've been living! Every few days, he had to endure Doma's noise attacks. How much longer would this continuous harassment last? For the first time, Akaza tasted despair.
Most importantly—he could sense that Doma probably really did want to have a good relationship with him, but he was completely unaware that there was anything wrong with his own behavior! And this guy couldn't understand human language, always misinterpreting his meaning. There was really something wrong with his brain.
Because of this, Akaza couldn't completely regard Doma as an enemy. In short, he wasn't exactly hateful, but he was incredibly annoying. It felt like dealing with his own mischievous child.
"Lord Akaza~" Doma was still chattering. "Have you missed me these days?"
"Although we talk often, it's still more intimate and comfortable to chat in person."
"Are you still not free recently? That's so disappointing. I really want to play with Lord Akaza."
"Ah, right! There's a fireworks display at my place in a few days. Lord Akaza~ Shall we go see the fireworks together?"
"Please, please, Lord Akaza~ I've been looking forward to it for so long!"
Akaza ground his teeth, his clenched fists making a cracking sound. As expected, I should just smash this guy's mouth!
Twang—
A sound from the biwa saved Doma's mouth. Several wooden platforms slid over smoothly and joined together, with a few scattered figures standing on them. Apart from the temporarily vacant position of Upper Moon Six, all Twelve Kizuki were actually present.
"Lord Muzan has arrived," Nakime's calm and cold voice came.
"An unexpected variable has appeared," Muzan's voice sounded, and it was clear he was in a very bad mood. He stood on a high platform, looking down at the kneeling demons, his pale and handsome face terrifyingly grim.
It all started a few days ago. That night, after finishing a drug experiment, Muzan was idle and decided to go out into the courtyard to enjoy the moonlight. He also rarely paid attention to the intelligence transmitted from his dying subordinates but found something unusual. A demon had been eaten by another demon!
At first, Muzan just thought a demon had defied his orders and was secretly eating other demons. But when he sensed the demon that had devoured its own kind, he was shocked to find that it was not under his control. As the Demon King, he couldn't even sense its existence!
"Another demon that has escaped my control..." Muzan covered his face, his plum-red eyes trembling slightly. At that moment, the thing he had always worried about had become a reality. He couldn't help but think of that woman, Tamayo, who was the first and only demon to escape his control in hundreds of years.
Although Tamayo had only managed to escape his control when he was at an unprecedentedly weak state, from that time on, Muzan began to guard against his subordinates' betrayal and no longer allowed demons to gather together. But now... another demon had appeared that was out of his control.
"Could it be the work of that woman, Tamayo?" Muzan couldn't sit still. He contacted Nakime, planning to go see for himself. In this situation, he couldn't trust any of his subordinates.
However, apart from the demons with some potential that he paid special attention to, he could only sense the general direction and location of the others. After being transported to the vicinity by Nakime, Muzan spent a few days in the area, creating a few demons to help him find clues, and finally succeeded in catching the rampant demon.
It was a demon with a black cross-shaped star mark on its forehead. It lacked clear reason and was completely unable to communicate. So Muzan directly transformed his arm into a giant maw, devoured its head, and extracted its memories. From this demon's fragmented memories, he learned of the existence of Seiran.
A demon named Seiran, completely out of his control, possessed a very strange and dangerous Blood Demon Art—Assimilation. Seiran could eat other demons, assimilate them in his body, and then separate them out again. The assimilated demons would have a black cross-star mark on their bodies, be freed from the Demon King's control, and only obey Seiran's commands to a certain extent. These Star Demons could act independently but were almost entirely dominated by instinct, no different from wild beasts.
Most importantly, they ate both humans and demons, and their strength grew very quickly!
"Abandoning reason and burning their life force in exchange for stronger potential and a faster growth rate?" Through studying the body of the Star Demon, Muzan came to this worrying and infuriating conclusion. The seemingly endless life of a demon was burned down to only a few decades or a hundred years. Perhaps it could be replenished a little by eating, but not by much. In exchange for this, a demon that originally didn't even have a Blood Demon Art had successfully awakened one, and the speed at which it grew stronger by eating was also faster.
"So far, a Star Demon with two cross-stars has already appeared?" Muzan perceived this from the demon's memory. These Star Demons seemed to be distinguishable in strength by the number of cross-star patterns on their bodies. A two-star Star Demon was still pathetically weak in Muzan's eyes, but it was a slightly larger ant.
"But if a demon with more potential is assimilated by Seiran, or, if one of the Twelve Kizuki is assimilated..." With such potential, it was hard to imagine how strong they could become. Even with a short lifespan, they would be a big problem.
"I must deal with Seiran as soon as possible!" This was also the purpose of Muzan summoning the Twelve Kizuki today.
"For the time being, you are to devote all your efforts to tracking down clues about Seiran and the Star Demons."
"Kill any demon with a cross-star mark on its body. I permit you to devour them."
"Once you find any trace of Seiran, engage him and report to me immediately!"
After giving his orders, Muzan left in a hurry.
"Seiran? Star Demons? Mmm—it seems something interesting has appeared~" Doma knelt on the floor, curiously checking the information transmitted into his brain, especially the image of Seiran. He didn't recognize any connection between Seiran and the demon-eater boy he had met before. Because the current Seiran had completely changed, with the appearance of a strong young man, covered in black cross-star patterns, and even his aura and temperament had completely changed.
"How strange~ This kind of thing shouldn't normally appear, right?" Could this be the influence I've brought to this world? Doma tilted his head and thought, but couldn't figure it out.
Well, if I can't figure it out, I won't think about it. He shook his head and laughed without a care. He was about to say something when Nakime kicked him out of the Infinity Castle.
