Sol's gaze swept over Yuta and the others before he turned away, leaving the matter behind.
Perhaps he could see what these "seeds" from another world might grow into when planted in more fertile "soil."
His reluctance to deal with further complications ultimately made him change his mind.
The spatial fluctuations surrounding Sol quietly dissipated.
He glanced at Child Emperor beside him and calmly instructed, "Arrange it. Their authority will be the same."
He then paid no further attention to Yuta and the others, whose faces immediately lit up with excitement and disbelief. Instead, he turned toward Tatsumaki.
"Let's go."
Tatsumaki snorted, hugged her doll, and followed him as though what had just been decided was nothing more important than choosing what to eat that evening.
Gojo Satoru smiled and gave his still-excited students a thumbs-up before casually following them, apparently intending to continue his life as an "observer of other worlds."
Child Emperor pushed up his glasses and formally addressed Yuta and the others.
"Well, everyone, welcome to the Hero Association's temporary membership roster."
"Now, please follow me to complete the necessary procedures and receive your training schedules."
In the reception room, Yuta, Nanami, Maki Zen'in, Panda, and Toge Inumaki exchanged glances. Excitement and determination were evident in everyone's eyes.
Child Emperor worked with remarkable efficiency. He quickly processed their temporary authorizations and sent their respective training schedules to their communicators.
"Well then, I wish you all a smooth training experience," Child Emperor said before turning and leaving to continue with his own responsibilities.
Yuta looked at the densely packed training schedule displayed on his communicator and took a deep breath.
"Let's begin."
Over the following days, Yuta and the others became completely immersed in high-intensity training.
Bang's Water Stream Rock Smashing Fist fundamentals greatly improved their control over their bodies. Tanktop Master's muscle training rapidly enhanced their physical abilities, while Metal Bat's practical combat sessions allowed them to quickly turn what they had learned into actual fighting strength.
Nanami was particularly impressed by the Hero Association's efficient training facilities.
Meanwhile, in the main hall of the Hero Association Headquarters, the orderly atmosphere suddenly became tense.
Numerous staff members and lower-ranked heroes involuntarily stopped what they were doing. Their nervous and curious gazes turned toward the main entrance.
A group of figures with wildly different appearances and powerful auras swaggered into the hall.
At the front were several Monster Association executives: Psykos, Rover, Black Sperm, Gums, and Nyan.
Aside from Psykos, who made no attempt to conceal her non-human appearance, the energy radiating from the others was enough to make the atmosphere feel heavy.
Even more striking was the presence of several individuals with entirely different temperaments among the Monster Association's ranks.
One of them was Muzan, a black-haired man dressed in a traditional kimono. His appearance was both handsome and distinctly feminine. Several Upper Rank Demons accompanied him.
As their progenitor's strength increased, their own power had rapidly grown as well after consuming Sol's blood.
Once their lives undercover had come to an end, they had left the Hero Association and joined the Monster Association, preferring its more straightforward atmosphere.
Thus, this unusual group, composed of former Monster Association executives and demons led by Muzan, had suddenly appeared inside the Hero Association Headquarters.
"Tsk. Still so sanctimonious," Black Sperm muttered disdainfully as he looked around the clean and brightly lit hall.
Psykos pushed up her glasses. Her gaze swept across the hall before finally settling on Child Emperor and several S-Class Heroes who had hurried over.
"Where is Mr. Sol?" she asked calmly, her voice carrying an unmistakable sense of authority. "We have come as agreed for a friendly exchange."
Child Emperor looked at the unexpected visitors.
Although he had been mentally prepared for their arrival, he still felt a slight chill run down his spine.
He maintained his composure and replied, "Mr. Sol is not currently at Headquarters. The exchange will be coordinated by me and Zombieman."
At that moment, Yuta, Gojo Satoru, and the others heard the commotion and rushed over from the training area.
The moment they saw the strange and intimidating visitors gathered in the hall, Yuta and the other Jujutsu Sorcerers immediately became vigilant, instinctively adopting defensive stances.
They could clearly sense the oppressive aura radiating from the newcomers.
The pressure was particularly intense from the feminine man in the kimono and the blue-haired woman. Their strength was difficult to comprehend.
"Oh? New faces?" Muzan's crimson eyes swept lightly over Yuta and the others, a faint smile appearing on his lips. "Their auras are somewhat interesting, but they're still very inexperienced."
Gojo Satoru, however, looked delighted.
His Six Eyes excitedly analyzed the newly arrived powerhouses.
"Wow! What a great day! Another bunch of powerful guys I've never seen before! This is going to be fun!"
Metal Bat, his bat resting over his shoulder, casually walked in front of Psykos.
"Hey, Monster Association, you're here. I heard you've got some good fighters over there too. Come on, I'm itching for a fight. How about a spar?"
Tanktop Master stood steadily nearby, his muscles bulging as his gaze settled on the enormous forms of Rover and Gums.
