High School DxD Crossover: Defying The Heavens

Floating mid-air in front of Issei, a bright, white, round object could be seen. It was roughly the size of an apple, and around it, a green fog existed.

The moment he saw the strange pearl-like object, the feeling in his mind increased a hundred-fold. He was no longer in control of his own body as he stepped forward, approaching the object.

After getting five-meters away from it, he could sense a faint smell of Spiritual Medicine. Nonetheless, he continued forward.

After standing in front of him, his hand reached out and grabbed it.

Instantly, he had a feeling that he should swallow it.

Normally, Issei would never swallow a foreigner object, but his body wasn't in his control. He could only helplessly watch as he placed the object in him mouth and swallowed it entirely.

The moment it fell down his throat, an intense pain flared up inside him. He could feel as the object literally fused with his body.

The pearl-like object lost it's shape, becoming a mist inside his body that was absorbed by his bones, bone-marrow, skin, organs, blood... It completely assimilated into his body.

He had truly become one and only with that strange, shining object.

Once the fusion was done, the pain gradually decreased.

Panting, Issei sat down on the ground. He could already control his body, and the first thing he did was to see if it had made any changes in him.

The first thing he noticed was that he was now in the fifth level of the Nascent Profound Realm!

"Fifth?" asked Issei in disbelief as he checked himself again, the result being the same.

"Finally!" He screamed in joy. He never would have thought that swallowing such a small pearl could cause his cultivation to increase by two levels!

But, the perks that it had brought him didn't end there. Just after checking his cultivation, a voice appeared in his mind.

"Sky Poison Peal," The voice began in a wizened tone, "Ranked fifth in the seven Heavenly Profound Treasures; limitless inner space, can counteract all poisons, refine all ingredients, ultimate plant harvest, treasure finding, innate poison concocting."

Sky Poison Pearl? Heavenly Profound Treasures? What the hell?

Before Issei could voice his doubts, the voice continued.

"After assimilation, the Sky Poison Pearl and the owner becomes one. They can never be separated, nor can their bond be broken."

"Abilities explanation: Limitless inner space – The Sky Poison Pearl possesses a limitless inner world capable of storing any kind of entities, be it living or not. Will preserve the state of the objects inside it; Medicine will never expire and corpses will never rot.

Warnings: Innate poison concocting has a limit to how much poison the Pearl is able to expel daily. If limit is trespassed, Pearl forever loses the innate poison concocting ability."

When the explanation was finished, Issei was heavy breathing. To actually find such an object by chance.. what kind of luck did he have?!

"Impossible..." Issei muttered as he recalled the pearl's function again and again. He couldn't believe his luck!

"Well," Issei said once he had regained his composure, "It's time to try it out."

He then decided to try out one of the abilities, the limitless inner space. According to the voice, all he had to do was to think of it and he would be teleported there.

Deciding to place his faith in the voice, Issei imagined entering the inner space. Immediately, in the center of his left palm, a small drawing of the Sky Poison Pearl appeared and flashed with a faint, green, light.

Soon after, a slight dizziness came over him and he unconsciously closed his eyes. When he opened them, his entire world was flooded in green.

This world of green was wide and open. There were no boundaries to be seen and there was a faint scent of the Sky Poison Pearl throughout this space. Immediately after entering, Issei understood that he had entered the world inside the Sky Poison Pearl.

"It truly is limitless..." murmured Issei as he cast his gaze at the horizon. The world truly had no boundaries. The entire place was plane, without even a hill, and was completely covered in lush, green, grass.

After looking at it for a bit, he decided to test the method of leaving it.

Issei closed his eyes and concentrated his thoughts. Suddenly, the world of green hastily dissipated, and when he opened his eyes again, what appeared before him was the dark and desolate cave

Staring at the faint green mark on his left palm, a smile flashed across Issei's face.

Even though he did not know why this ridiculous event of finding such a strange pearl by chance occurred, he couldn't be happier.

"Wait..." Issei then remembered something. The voice had said that this pearl that belonged to him was ranked fifth out of seven of the Heavenly Profound Treasures.

As he thought that far, he couldn't help wondering what this Heavenly Profound Treasures were and what could possibly be more amazing than such a pearl.

Since he had no way to find anything out, Issei decided to explore the world of Sky Poison Pearl again. Who knows? Maybe there was previous owner before him and he had left something there.

He then walked to the nearest wall, sat down and closed his eyes.

The Sky Poison Pearl mark on his left hand's palm flashed again, and he was once more in the boundless green world.

After looking around a little, the only thing that Issei found was a worn out map.

After analyzing the map, Issei found out that there was some similarities between the forest he had just been in and the forest on the map. Also, the cave he was in was also shown.

Seeing that, Issei smiled. He had found his way back!

Sadly, the map was a little out-dated. Apparently, it was from before that the Heavenly Might School was built, which means that it didn't show the school's building, but Issei was able to roughly figure out where it was, given some physical land marks that were shown in the map that he had seen on the way to the school.

After looking through it, Issei figured that the map was, at the b.a.r.e minimum, ten thousand years old. He figured that out because the age of the Heavenly Might School was nine thousand and nine hundred years old.

Also, on the map, there was a blood-spot that looked to have fallen just a few days ago. It was on top of one of the mountains that were on the mountain range just beside the Heavenly Might School.

He immediately figured that the owner of the map ha been bleeding when he last opened it, causing the blood drop to randomly fall on top of the map.

He also knew that the only reason why the map was still intact and that the blood drop looked recent was all because of one of the bonus properties of the limitless space within the Sky Poison Pearl.

It was the one made it so that everything that entered the Sky Poison Pearl's inner world would remain in the exact same condition it had been the moment it entered. It would not rot, not age, not dry.

All in all, it was a perfect storage for Spiritual Medicines.

After taking a mental picture of the map, Issei placed it back in his Sky Poison Pearl and walked out of the cave.

As he looked at the starless sky, a cold smile flashed across his face. He would make sure to pay back Jiao Lei the favor that he had given him!

If it wasn't for his great friend Lei, Issei would never have acquired the Sky Poison Pearl. He would be sure to give him a good, beautiful present back.

"Well, let's just hope that he likes being beaten to the point that his mother can't even recognize him..." said Issei in a sing-song tune as he walked out of the cave and into the forest.

He didn't care whether he had acquired the Sky Poison Pearl thanks to him or not. What mattered was that he had wanted to have Issei killed by beasts, and Issei would be sure to pay back the favor.

Issei wouldn't kill him, since he still couldn't go as far as killing. Although Issei was extremely smart, he was still a ten years old kid. Breaking bones and shattering organs was fine, but killing was still too much. As long as he didn't take any lives, it was fine.

Three hours later, Issei was already standing in front of the School's inner area entrance. On the way, he didn't run into any beasts, so it was a smooth trip.

After managing to enter the school without the guards guarding the entrance finding out. Because of the rank the Rank 2 Martial Skill, Dark Shadow, which allowed him to become completely dark, with the addition of the rank 2 Martial Skill, Feather Steps and finally the rank 2 Martial Skill, Light Sound, Issei was able to pass undetected by them.

Dark Shadow was used to make him undetectable when hiding in shadows, and since it was night, he was practically invisible. Feather Steps increased his speed, so he used it to make him walk faster. Light Sound made his steps and breathing soundless.

With all of that, entering the school without anyone noticing was rather easy. Also, the fact that the guards were sleepy helped. He knew that if they were concentrated on their task, Issei would never have been able to pass by them undetected, since both of them were at the peak of the True Profound Realm.

After entering the school, Issei started searching for a map of sorts that showed the places in the school.

Heavenly Might School, although not having a lot of prestige, not having a lot of power, was the school with the biggest area in the entire Azure Province. It was said that it was family inheritance of the first owner of the school.

Because of that, it took Issei well over one hour before he finally found a stone mural that showed a map of the school.

Issei's destination was the dormitory. After looking at the map and taking a mental picture, Issei walked around some more and after twenty more minutes, he found the dormitory.

Walking inside through a widow, he entered it, still using all of his three Martial Skills. Because of his immense amounts of Spiritual Energy, comparable to those of the True Profound Realm, Issei could still keep using the skills.

After searching around for a bit, he finally found a bed that wasn't occupied. Putting on new clothes and storing his wet ones away, Issei climbed onto the bed and was quick to enter the realm of sleep.
