Demon Lord's Reincarnation

In the Eastern demon lands near the border to the Northern demon lands was the Gelder plains. Two gigantic demons stood guard at this border. They had large muscular bodies that were colored red and blue. They stood around four meters tall and held onto huge clubs as their weapons. Two horns were sticking out of the side of their heads. These demons were called Oni, and the two who were guarding the border were the strongest of the Oni tribe. It is rumored that in physical strength alone, they could match the strength of the mighty Lord of the Lycans Kir.

The oni brothers who were usually bored because they had nothing to do noticed a flock of the winged demons coming towards them. When the two brothers saw the sight they got a little bit excited. One of the brothers picked up a boulder and threw it at the Tengus and Harpies.

The newly appointed leader of the Elite Guard saw the incoming boulder and ordered his men to fly low. After giving out his order the leader of the group sped up and flew directly at the Oni brothers.

"I have come to deliver a letter to Demon Lord Tsukiko." When the Oni brothers heard what the Tengu said, the two looked at each other. After a short while, the red Oni spoke.

"Show me the letter and I'll be the one to deliver it to our master."

"I can't do that. I need to be the one to hand it over personally. I must ensure that this letter gets to Demon Lord Tsukiko."

"Are you saying that we won't be able to do that?" The blue Oni stepped forward while glaring at the Tengu in front of him.

"It doesn't matter if you're able to do it or not. I must be the one to send it to her and listen to her reply."

The two Oni brothers now stood side by side their muscles bulging ready for action. The Tengu gave a signal to his subordinates and they surrounded the two. As the tension between the two sides were rising, a voice echoed through their heads.

"That's enough, let them pass." The voice that echoed was pleasing to the ear, making one feel comforted that was what the Tengus and Harpies heard. On the other hand, when the two Oni brothers heard the voice, they felt like it was ice cold and their demon lord wanted to kill them. Of course, that was only their imagination since Tsukiko was a playful demon lord who liked to prank people.

...

The two Oni brothers made way and no longer bothered the Elite Guard of the Overlord of the sky. Seeing the Oni brothers no longer blocking their path the Elite Guard continued on their journey.

...

The location of each demon lord except for Darius was known to most demons. That knowledge was regarded as basic information so that they could avoid the places were the demon lords reside.

The Demonic Fox Tsukiko lived under the tallest tree in the Eastern Plains called Jubokko. It was rather easy to spot from the sky, as the tree was enormous and was as high as a mountain.

...

The Kitsune tribe used to be a strong tribe with the greatest of spell casters. Yet a time came when they became too weak and only produced members with two to three tails. The number of tails indicated how strong a Kitsune was. At their prime, the tribe used to have several five tail foxes.

With their weakened status, the other tribes kept on harassing them. It seems like only a matter of time before their tribe became instinct. That all changed when Demonic Fox Tsukiko came into power. She was the very first Kitsune to gain seven tails, her power was phenomenal. But that wasn't enough for her to protect her tribe. So she started creating different unique spells to protect her tribe from the other demon tribes.

Overtime her power and influence rose, and slowly but surely without her noticing she had conquered the whole Eastern Lands.

...

The Elite Guard finally arrived at Jubokko, underneath it lay a fifty-meter large golden fox with seven tails. The Golden Fox looked at the flying demons and yawned. When the Elite Guard saw Tsukiko for the first time they were frightened.

Was the Kitsune before them still considered a demon or was she a monster or some kind of dragon, her size was too big. The Elite Guard cautiously landed on the ground in front of Tsukiko.

When they saw her from the angle on the ground, she looked even bigger than when they were looking at her from the sky.

"Subordinates of the Overlord of the sky, why have you come to my territory?" The Golden Fox didn't speak using her mouth, instead, they heard her voice in their heads.

"Lady Tsukiko, I have brought a letter from our lord." When the Golden Fox heard what the leader of the Elite Guard said, she started to shrink in size. Once she was small enough Tsukiko turned into a human form.

Her fox eyes looked at the surprised Elite Guard. She couldn't help but giggle. It was always fun to watch the reactions of the people who see her true form after she shows the gigantic one. Tsukiko then approached the stunned leader of the Elite Guard and took the letter from him.

Tsukiko then read the letter, at the beginning she was smiling, but as she continued reading the letter she started frowning. Once she was done reading Tsukiko who usually had a playful aura started emitting intense killing intent.

"You tell your lord that no matter what happens, the answer is a NO! I reject his stupid plans, and most importantly I reject him! Now that you heard my answer go back to your lord and tell him what I said."

The Elite Guard were stunned and confused by what Tsukiko said as they didn't know the contents of the letter. Seeing as they weren't moving at all Tsukiko shouted at them again.

"I said LEAVE!" Tsukiko enhanced her voice using a spell which made her voice actually produce a gust of wind. The Elite Guard finally moved and fled the scene.
