Chương 12: Nezuko standing under the sun

In the midst of a dense forest, sunlight filtered through the gaps in the leaves, creating beautiful light patterns on the forest floor. However, this beauty couldn't erase the tension enveloping the Demon Slayer Corps training grounds. The Hashira gathered around the training area, looking uneasy, waiting for something they had never witnessed before.

In the middle of the crowd stood Haru, his gaze full of determination. Over the past two months, to accelerate Nezuko's transformation, Haru had asked Nezuko to gradually touch sunlight and allow her body to evolve more quickly. On the first day, Haru had her touch the morning sunlight with her finger. As soon as Nezuko's finger met the sunlight, it immediately emitted smoke and burned within minutes.

Despite the pain, Nezuko endured with extraordinary resolve. She continued this practice, and after a few days, even though her finger was still burning, the rate of her burning was slower than before, and she could withstand longer periods in sunlight without burning.

Every day, Nezuko underwent this torment while enduring immense pain. Watching his sister suffer, Tanjiro cried and embraced Nezuko, begging her to stop.

But Nezuko resolutely persisted, giving Tanjiro a reassuring smile. Seeing his sister's determination, Tanjiro could only support her with a heavy heart, feeling utterly useless as a brother for allowing her to endure such suffering. He trained even harder to protect Nezuko.

The other Hashira, witnessing Nezuko's determination, were deeply moved, and they recognized her as a member of the Demon Slayer Corps from the bottom of their hearts, even Sanemi, who had previously opposed Nezuko, was touched by her willpower.

After two months of adaptation, Nezuko finally reached the last step.

"She's coming!" shouted Tanjiro, his voice filled with hope and worry. All eyes turned to the path leading to the training area, and at that moment, Nezuko slowly emerged from the shadows of the trees and walked carefully into the sunlight. She stood there, her skin glowing under the sun, showing no signs of burning or pain.

The atmosphere fell silent for a moment as everyone was captivated by Nezuko's presence. Tanjiro gazed at her with tears of joy, while the other Hashira could not hide their astonishment.

"As I said," Haru stated, his voice calm yet confident, "Nezuko is the key to drawing out Muzan."

After a brief moment, tension began to rise. Everyone understood that this was not only about Nezuko's miraculous ability to walk in sunlight. This was a sign that their final battle was approaching.

"If Nezuko can fight in sunlight, then we cannot allow Kibutsuji Muzan to devour her to overcome his weakness," Rengoku said seriously. "But we must be prepared, for we know how powerful he is."

Haru nodded. "We must prepare ourselves as best as we can. We are not just facing Muzan, but also all the demons he will summon."

At the same time, shocking news arrived from Tamayo and Shinobu. They had completed their research to develop a cure that could turn demons back into humans. Although they could not change Muzan, they could impede his regeneration process and weaken his powers.

"This poison will accelerate the aging of demon cells," Tamayo explained in front of the Hashira. "We have tested it on several demons, and the results are promising. This could be a powerful weapon in our fight against Muzan."

"This is fantastic news," Shinobu said enthusiastically. "With this cure, our chances of defeating Muzan increase."

With all this new information, the training atmosphere grew increasingly serious.

"Every second is precious," Rengoku declared passionately, gazing at the Hashira with determination. "We must train ourselves to our limits. We must unite and be ready to face whatever comes."

All members of the Demon Slayer Corps nodded, a fiery spirit igniting within them. They knew that this was not just about them, but also about protecting humanity from the eternal threat created by Muzan and his demons.

Under the sunlight, Nezuko stood gracefully, feeling the warmth of the sun that she had long missed.

"Now that Nezuko has overcome the demon's weakness to sunlight, it's time to execute our previous plan. We will kill the two Upper Rank Kizuki that Haru informed us about…" Kagaya said seriously, explaining the plan again.

Based on the information provided by Haru that Kibutsuji Muzan could monitor every movement of the demons, they planned to use this to show Muzan that Nezuko had overcome the greatest weakness of demons, which was sunlight. They intended to lure Daki, the sixth Upper Rank Kizuki, until sunrise, where Daki would witness Nezuko, a fellow demon, overcoming their greatest weakness, which was sunlight.

Then Kibutsuji Muzan, sensing Daki's death, would surely investigate Daki's memories to see what had happened. Upon seeing Daki's memories, Muzan would undoubtedly see Nezuko under the sun.

The long-desired goal of a thousand years was now within reach. Although Muzan was a coward, he would surely take the risk to capture Nezuko and devour her.

The reason for choosing Daki over Doma was that Daki was weaker than Doma and easier to drag to the sunrise with the combination of several Hashira, plus Nezuko, Tanjiro, and Inosuke.

But there was one thing that gave the Hashira a headache at this moment: how to kill Doma. Not for any other reason, but Doma's Blood Demon Art was a natural enemy to their breathing techniques.

Doma's Blood Demon Art granted him powerful cryokinesis. He could generate ice and freezing mist from his flesh and blood, and could manifest it anywhere around him, as well as manipulate it at will, allowing him to unleash very powerful ice techniques.

Moreover, the ice created by his Blood Demon Art was deadly to those who inhaled it, causing the victim's lung cells to die and making it impossible for them to breathe very quickly. The ice and freezing mist were so cold that the air around Doma's freezing mist was cold enough to make someone's lungs feel like they were about to explode, and in the original work, it nearly froze Kanao and those around her upon mere contact.

After lengthy discussions, they divided the forces into two teams. Shinobu, Haru, Rengoku, Tokito, and Mitsuri would face Doma.

The other team, consisting of Sanemi, Usui Tengen, Giyu, Iguro, Tanjiro, and Nezuko, would confront Daki.

The reason Gyomei did not join was that they were concerned that the battle would force him to activate his mark before the final battle, so he remained at the headquarters to continue training the other Demon Slayer members.
