As Susie jogged through the nearly deserted streets, the crimson hue of the night sky cast an eerie glow, with the red moon and countless stars overhead lending an otherworldly atmosphere to the scene. Clutching the long object wrapped in white fabric, she quickened her pace with anticipation mingling with anxiety as she neared Seren's home.

Upon reaching the door, Susie knocked with a sense of urgency as her heart pounded in her chest. When the door swung open, she was met with the sight of Seren, his crimson eyes and long white hair framing his shirtless form, his chest rising and falling as he panted heavily.

Startled by his appearance, Susie's concern quickly overtook her surprise. "A-are you alright?" she asked, her voice laced with worry.

Seren reassured her with a nod as he tried to regain his composure. "Yes, I'm fine. Come in, we will get started immediately," he said, gesturing for her to enter.

As Susie stepped inside, her eyes widened at the sight of the room's transformation. At the center of the room was an elevated metal bed draped in white cloth. The bed was surrounded by an array of strange tools arranged on metal trays. A towering machine-like structure loomed overhead, while another contraption with tubes and small bottles attached to it stood nearby.

Intrigued and slightly apprehensive, Susie took in the unfamiliar equipment as her curiosity was piqued by the weird object.

While Susie had gone to get her arm from Luna, Seren had delved into the depths of his mind as he drew upon his perfect memory to reconstruct the intricate details of objects and machinery he had witnessed in different realities through the realm of nothingness. With meticulous precision, he pieced together a concept that he named ‘Nano Craft," which granted him the ability to create any simple object he desired.

At first, Seren had tried to devise a universal healing concept, but he soon realized a problem. The limitations of his abilities became apparent as he discovered that he could only heal superficial wounds, with little hope of successfully reattaching a severed limb.

Resigned to the challenges before him, Seren abandoned the notion of an easy solution, recognizing the need for caution and prudence in his endeavors.

Seren dedicated nearly three hours to creating his concept and another hour to crafting the necessary equipment for the surgery.

However, Seren soon discovered that even with this newfound power, there were inherent limitations which were automatically imposed upon his abilities. He found himself restricted by two fundamental constraints: the size of the objects he could create and the inability to replicate unique items such as Susie's scythe from the Luminar Tree or complex materials.

By the time Seren had finished creating all the essential items needed, his soul reserves were fully depleted.

As Seren approached Susie, his expression remained impassive as he said in a commanding voice. "Take off your clothes," he instructed, his tone matter-of-fact.

"???" she stammered as her mind for a second stopped working when she heard this.

Confusion and embarrassment quickly swept over Susie, her cheeks flushing with heat as she struggled to comprehend his request.

Observing Susie's flustered state, Seren clarified his intentions with a flat tone. "The clothes will get in the way during the reattachment," he explained succinctly.

Reluctant but understanding the necessity, Susie took a moment to compose herself before complying with Seren's request. With a mixture of embarrassment and resignation, she removed her shirt, her arm instinctively covering her chest in a gesture of modesty.

"...I don't need to take off my bra, do I?" Susie queried tentatively, her voice tinged with uncertainty. Seren, preoccupied with inspecting the severed arm, responded without looking up. "No need, just lay on the metal bed," he instructed with his attention fully focused on the task at hand.

Feeling a twinge of annoyance at Seren's apparent indifference to her body, Susie complied with his instructions, her frustration momentarily overshadowed by the gravity of the situation. With a sigh, she reclined on the bed as her mind raced with a mixture of apprehension and determination as she prepared herself for the procedure ahead.
