Deep in the interstellar abyss, the Wingdivers from the EDF series, elite female infantry units, were on a reconnaissance mission. They were majestic, shimmering in their metallic armor, resembling heavenly beings.

Their mission was simple - to secure the vast, seemingly quiet expanse of the galaxy. But the unknown often harbored the most chilling threats. And that's when they encountered it - Rei Ayanami in her Angel form.

Rei, the synthetic human from the End of Evangelion, now taken the form of a gargantuan Angel, was a chilling sight to behold. Her ghostly hue reflected in the eyes of the terrified Wingdivers.

But they were not ones to back down. With a determined resolve, they planned their attack strategy. Yet the Wingdivers were not prepared for the ordeal that awaited them.

A battle of epic proportions unfolded amidst the starry expanse. The Wingdivers unleashed their energy weapons, streaks of fiery light slicing the void. Rei, however, was not easily shaken.

Evading their attacks with ease, Rei retaliated with her own deadly attacks. The catastrophic energy waves sent the Wingdivers spiraling backwards. Their bravado was slowly withering away.

Rei had an odd fascination towards these metallic angels. A twisted desire surged within her. She yearned to sate her hunger by devouring these celestial entities.

The Wingdivers were shocked as Rei's form changed, her mouth widening into a gaping abyss. In a swift move, before any of them could react, Rei swallowed them whole.

Inside Rei's stomach, the Wingdivers found themselves in a grotesque world. Panicked, they tried to escape, but the fluidic walls of Rei's stomach closed in on them.

Acid began to flood in, corroding their sturdy armor. Their desperate attempts to escape seemed futile as the acid started to eat them alive. Rei reveled in her victory, satiating her twisted hunger.

As the acid continued to dissolve them, the Wingdivers realized the direness of their situation. Their struggle became desperate, a fight for survival. Would this be their end?

Or could they turn the tables and claim victory against the mammoth angel? Their spirits ignited with a newfound resolve. Each blow they struck against Rei's interior became more powerful.

To their astonishment, Rei started to wince. The Wingdivers were causing her discomfort. With a surge of hope, they increased their efforts, hoping to break free.

Rei, on the other hand, was taken aback. She hadn't expected resistance. She could feel the Wingdivers fighting back, their relentless effort echoing within her.

As the resistance became more apparent, Rei experienced pain. Fear gripped her for the first time. The once dominant angel was now at the mercy of the metallic angels she'd swallowed.

The Wingdivers broke free, bursting through Rei's form. They emerged victorious, their metallic armor shining more brightly than ever before. Their determination had saved them from a horrendous fate.

Rei shrieked in agony as her form dissipated. Her dominance had been shattered by the resilient Wingdivers. Her once terrifying form reduced to mere cosmic dust.

The Wingdivers stood tall amidst the cosmic debris, a testimony to their bravery. They had faced the most chilling threat, yet their spirit stood unbroken. They were the true victors of this cosmic battle.

The victory, however, came at a cost. Their once pristine armor now bore the marks of the deadly confrontation. But these scars were a testament to their brave fight. They had survived the angel's stomach.

Slowly, the Wingdivers made their way back towards their ship. Their journey had taken a detour of horror, but they emerged stronger. They had confronted death and lived to tell the tale.

This epic battle was inscribed in the annals of the EDF series. A tale of the Wingdivers' bravery, their survival and victory against Rei Ayanami. A story that echoed across the cosmos.

The battle taught the Wingdivers a valuable lesson. It was not their metallic armor or their advanced weaponry that saved them, but their courage, their will to survive. Their spirit was invincible.

In the end, Rei's hunger was quenched, not by the destruction of the metallic angels, but by their victory. She had underestimated their willpower, a mistake that cost her everything.

As they soared through the cosmos, the Wingdivers felt a change within them. They felt a sense of accomplishment, a newfound respect for their fellow soldiers and themselves. They were not just soldiers, they were survivors.

The universe was once again plunged into silence, the aftermath of the battle fading away. But the echoes of the Wingdivers’ bravery continued to resonate, a testament to their spirit. The tale of the metallic angels who survived the belly of an angel would not be forgotten.
