Reincarnated as an Energy with a System

A massive battle had taken place in a world that was invaded by demons.

This battlefield was located right in front of what was considered to be the final haven for humanity. All other humans in the world had died at the hands of the demons, and this was their final strike before they would eradicate all life on this planet.

The demons were here to either enslave the planet or destroy it. The Bondforgers of this planet had been fighting the demons for nearly 2 years now.

No one knew how the demons were capable of opening portals over to other planets, but they had done it and now they were here to destroy Aimee's home planet.

Aimee, a blue-haired girl, sent out a ball of fire toward the flying demon that couldn't even speak. It looked more bug than anything as it flew around the battlefield, along with many other such bugs.

Aimee's fire struck the demon right into the throat and blasted it into two.

However, that was just a single kill in what looked like a million different demons flying toward her.

The flame in her hands turned into a spear that she launched as far as she could and surprisingly managed to impale two demons at once.

Despite that, they were still losing. They had already lost 3 of the 5 Spirit bonded fighters in their military, and now two more were fighting high in the air against the generals of the Demon army.

Lightning flashed in the sky and something fell to the ground next to Aimee. When she looked at what had fallen, Aimee recognized her commander that was fighting.

She was one of the remaining two spirit-bonded fighters, and now she was dead.

She looked high in the air and saw the one remaining commander fighting with all he could.

The wind ripped every common demon that approached him, but the generals still fought him and gave him a hard time.

Aimee turned to look back towards the giant wall that protected the normal survivors behind it, and then at the mountain, the peak of which was known to have a spirit living on top of it.

A man appeared next to her and jammed a sword into the throat of the demon that was trying to attack her while she was distracted.

The man was about to shout at her for being distracted when he too saw the corpse next to her.

"Is that..?" he asked.

"The commander," Aimee said. "We're going to lose if we go on like this."

"What can we do but fight?" the man asked.

"I have a plan," Aimee said. "It's our last hope."

"What plan could poss—"

Before the young man could finish his statement, a demon pierced his chest from behind using its horns.

"You bastard!" Aimee cried and sent a fire spear through the demon's chest and killed him.

The young man slipped from its horns but fell to the ground dead. Aimee was devastated.

She turned around to look away, but then she saw her commander's corpse. When she turned in the other direction, she saw nearly a thousand different corpses. Most were civilians fighting to the death to get rid of the demons, but a few were from her corp.

Her eyes grew hateful with anger as she turned to look at the demons. However, there wasn't much she could do with her Rank 5 powers and blue hair.

She needed something good. She needed something better.

She turned back towards the mountain and decided to go along with her plan.

Aimee ran away from the battlefield and towards the wall. She feared what the security would do seeing her run away from the battlefield, but when she arrived at the gates, she realized it was wide open, with corpses strewn everywhere.

Was it demons? Or deserters from the battlefield? She didn't have a tie to think.

Aimee blazed through the road of the city, past the many corpses, ignoring them all, and not even waiting to see if any of them belonged to her little sister.

She couldn't afford to stop.

She finally arrived at the foot of the mountain and then ran up the mountain as fast as she could. Her legs hurt, and her feet blistered, but she persevered and kept going.

Sounds of battle rung even this far away, and she could hear the cries of the dying in the city down below.

But she couldn't afford to stop and take it in. She continued running.

Finally, after nearly half an hour, she arrived at the peak of the mountain and saw a massive lake in it.

At the center of the lake was a small piece of land with a gigantic tree growing on it.

This was where people had said that they had seen a spirit many times before. But no one had seen it twice until now, so all she could do was hope.

She jumped into the water, and using the fire she could create, she blasted her way over to the small island.

She climbed up quickly and looked at the tree.

"Spirit! Come out, please," she said. "We need your help."

Silence. There was no sound from the tree. Was the rumor wrong?

"Spirit, if you are there, please come out. We need your help," Aimee cried. "The demons are killing us. Please, help us."

There was silence again.

Aimee didn't know what to do. If there was no spirit here, then…

Something flew out of the tree in a lazy fashion and flew at eye level around Aimee.

"A spirit!" Aimee's hope was rekindled.

The feminine spirit looked at Aimee curiously and moved around her, checking everything.

"Who are you, little blue-haired girl?" the spirit asked.

"What? You can speak?" Aimee was surprised. She had never heard of spirits being able to speak at all.

"Do humans answer questions with a question?" the spirit asked.

"Question? Ah, sorry. My name is Aimee, spirit," Aimee replied.

"Aimee, huh?" the spirit nodded to herself. "I have a name too."

"You may call me, Saphandra."
