An eye started forming on the ground, surrounded by burnt out metal bits all over the ground

The eye started rotating around, rolling on the ground as it seemed attracted to other parts of broken and melted metal all around

Slowly, as a short amount of time passed, the eye started joining up to other metal bits that bent and started to form a face, slowly being magnetically joining up with other bits to form a head

As that happened, a semblance of intelligence formed in the eye as some remnant consciousness seemed to awaken, as some sort of self repairing mechanism attracted other parts of what looked like a head continued pulling itself together

Not far off, a skeleton that was wearing what looked like a metallic vest that was actually a metallic upper torso started pulling together magnetically metal organs at itself, crushing the skeleton's ribs inside as the torso reformed with all it's organs 

The skeleton collapsed as the torso started moving together towards the reforming head as it started to become recognizable 

If one was to look at it, it was healing at such a rate that the healing was imperceptible at first

But as one looks at it, then looks away, looking back at it would surprisingly show a different body part formed

All around the newly forming being, stood skeletons standing around with rusty weapons and tattered armor and torn clothes

As Hiro's consciousness recovered, he looked at the various skeletons, some of them wearing the torn skin of Reika, one wearing the skin of her chest like a torn shirt, her breasts rotting on the skeleton's body, while another skeleton wore her crotch upside down on it's head like a hat, her rotten pussy torn and pulled apart to form eye holes for the skull of the skeleton

He didn't know where the rest of her body was, and wondered whether her skeleton was one of these undead skeletons wondering aimlessly around

The decapitated and torn apart giant torso of Chiho lay on the ground nearby, her ribs showing as several cavities in her chest and groin were gaping open as several skeletons camped at her pussy entrance, using it like a cave where they stood around aimlessly

Chiho's giant head lay not far away as her other giant body parts lay rotting all around

By now, Hiro had a substantial part of his body recovered. but he had yet to recover his limbs, sitting with just his head and torso on the ground

He wasn't only rebuilding himself from small metal bits of himself, but also larger parts that seemed to independently bending itself back into pieces and moving into place on and in his body

His back opened up and he fired multiple small rockets as the skulls of the skeletons around him all exploded, including the skeleton with the now torn pussy skin of Reika

Without the lich around and his more powerful servants, the basic skeletons were no match for Hiro's weapons

In an instant, only Hiro was left in the abandoned area with multiple headless skeletons and the rotting remnants of his lovers

Although Hiro felt that he was no longer human, he still felt regret as he had enjoyed the company and the sex with both Reika and Chiho

When he was alive, they were his favorite bikini model and AV star, and he had never imagined meeting them, let alone fucking them, and he retained his human memories of being extremely attracted to them

He stood up after joining back his legs and arms, bending his arms to test it and finding that he was satisfied with his body

He sighed and started gathering the remnant body parts of both girls, trying to heal them, as he could when they were alive. But they were dead and his healing ability didn't work

Suddenly, his penis grew erect as he held Reika's skin with the torn pussy. Hiro was shocked that he was horny at such a time

A beam of light shot out of the glans of his penis, like a light projector as he started to 3D print with the light, forming an organ floating in the air, literally just touching the tip of his penis

Hiro was stunned, seeing a organ floating in the air as his penis continued 3D printing other organs that was attached to it, forming all around his cock

He recognised the first organ as a female womb, joined with the other female internal organs

But he had no control over what was going on, and he watched as his penis moved by itself, "drawing" the female body parts that was starting to form on and over his penis!

Wasn't this a bit like Reika's powers to "3D Print" weapons from her nipples?

The body started to grow on his penis and after a short while, and the naked female torso that formed suddenly started moving as if fucking him

Arms formed on the body and it started groping him and hugging him as the headless body fucked him mindlessly

He didn't want to stop the body, both aroused by being fucked, and curious what was happening, and realizing that fucking the body felt familiar

As the beam started "printing" the bottom part of a face, the mouth started kissing his mouth and mouthing "Kei... oh Kei" in Reika's voice!

The beam continued and the familiar face of Reika was formed right in front of him, her eyes closed as she lustfully fucked him

His "heart" raced as he was glad that Reika was still with him, in a position he enjoyed being in

He remembered that as they had fucked before, she was fucking him as a replacement for her own lover, Kei Kurono, even imitating his voice and mannerisms while she kept her eyes closed.

He had did this for Chiho too, and he wondered if Reika or Chiho even had feelings for him. He regarded himself as a robot after all

"Hiro?" Reika said as she opened her eyes, finding that "Kei" was not responding and seeing Hiro's face, remembering that he was just imitating Kei for her benefit. 

Hiro had also shortened his dick to the dimensions Reika said Kei was, but now he was his longer self. 

She looked at him and realized that her surroundings were not familiar

She quickly got off from his lap, and was shocked to see the ruined city all around and the many skeletons dead all around

"What happened? Where are we? Where is Chiho?" she asked

But as Hiro was about to answer, his still erect penis started to shoot out a beam, 3D printing again starting from a female uterus on his penis again

This time, Hiro didn't guess who it was, knowing that it would be Chiho

Reika watched, having experienced the Gantz system. Hiro's penis was 3D printing Chiho the way the Gantz ball printed each of them in the Gantz room, only that Chiho was being printed from within her body from his penis

The body started being constructed, and when it was only a headless body, started fucking Hiro again, like Reika did

Again, when the mouth formed, it was calling "Rei" in Chiho's voice 

Hiro kissed Chiho and hugged her and Reika looked at him funny

Chiho opened her eyes, looking at Hiro, then at Reika

Chiho smiled and kissed her, surprising both Hiro and Reika

"What's going on here Hiro?" Reika asked as she looked around

Only now Chiho realized this was a different place. She noticed the giant rotting remains of a female nearby and saw the skull with no eyes and it was then that she realized that the giant skull's hair was the same as hers

"Is... is that me?" Chiho asked, getting off his cock

"Yes. How much do you guys remember?" Hiro asked

Both of them started explaining that the last they remember was fucking him and now they were here. Hiro explained what had happened after that, finding the city to being surprise attacked by the undead

They understood that they had died and that when they fucked, Hiro's body "saved" them at that point, like a save game at that point

They didn't know that Hiro could do that, but Reika said it must be another adjustment to their bodies, like her Gantz system in hers, and Chiho Gigant system imbedded in her.

After told them about the lich and all their deaths, they looked somber but were grateful that they were alive

They didn't want to run into the lich again, and decided to leave and take their chances in the wilderness beyond the city

Deciding to get out of there, they huddled together and hurried out of the city, lest the lich and his more powerful minions returned
