Grimm Overlord (Male Reader x Overlord)

Through Dimensions

Y/N sat on the throne he took from the high elf ship as it floated over a large empty plain in the Demi-Human territory. He had had all nanobots clear out an area of 10km x 10km before putting them all away again

"Let's see if this will work," He said before opening Gates of Nazarick and having the 2 sirens he converted drop out. They both fell to their knees before him and waited for his commands "Tessaract, you can open holes in dimensions correct" he asked

"Yes master" was her simple replyed, Y/N nodded "Good, I want you to open a portal for me, to a planet called Remnant. I will boost your power as well to help in the process" He said to her in a commanding voice

"At once master" Tessaract stood from her position on the floor before putting her arm out with her hand diagonal from her body. she stood there for a solid minute before cracks started to form in the air before her

Seeing this Y/N started pumping unimaginable power into her, so much that it was almost painful for her to bear, but in the end it worked as the shards in the air started falling out revealing a swirling blue portal

"Good, how long will this portal last?" he asked as he began standing up from his throne and started descending towards the previous siren empress, "It should last for 24-hour master, there is a powerful force trying to close it on the other side though so it  may be shorter"

Y/N nodded "Alright, I will have to get some things so long, keep this portal open as long as possible, that is an order!" he commanded before teleporting into his castles throne room

"[VOICE MAGNIFY]" he cast the simple 3rd tier spell before speaking "ALL HIGH TIER GRIMM, REPORT TO ALL AVAILABLE SHIPS, WE ARE LEAVING TO RETRIEVE THE QUEEN" All was silent for a while, until a massive cloud of dust formed in the distance

Millions upon millions of Grimm of all kind rushed towards where the ships were kept, everything from high to mega tier rushed past the castle at their max speed, the Desghidoras carried different Grimm on their backs while the Grimmzillas had Grimm cling to their armour plating

"Father? What is going on?" He heard from behind him. Turning, he saw Blake, Neo and Snow kneeling before him at the foot of the stairs to his throne. "I have managed to get a crack to the planet your mother is on"

All three gasped before jumping up to their feet "I will get Yang, Raven and Rose" Blake said before running into a shadow to teleport to their locations. Y/N turned to Snow and Neo, "Go get on the ships and keep the Grimm in line, I will be launching the mega-ships for this", They nodded before running off to do his commands

"Don't worry Salem, I'm coming" he said before opening a Gate to Ainz office

TIME SKIP

"What are you telling me this for! Go get your wife as soon as you can! I will inform everyone of your departure! Now go, go, go!" Ainz said before moving faster than you would think possible for a body of bones

TIME SKIP

Y/N now stood next to Tesseract as she held the portal open "We need to make this portal bigger, is that possible?" he asked her. The max size she had been able to make it was a single kilometre high, hot even half the size of the ships he needed to get through

She thought in silance for a second before turning back to him "Can your ships fly straight down if I put the portal on the floor?". 'What a question he thought before doing some calculations in his head

"[MESSAGE] All ships, go into orbit and prepare for straight down dive, I repeat, prepare for a straight down dive!" he commanded before turning back to her "Lay it down". Tesseract nodded before floating off the ground slightly and rotating the portal onto the ground till it covered all of the open land he had set aside for this

"C-Cant hold i-it much longer m-master" She stuttered out in strain. "It's alright," He said before recasting the message "All ships besides mine! Drop! Drop! Drop!" and just as he finished saying that 1000s of ships zoomed past and through the portal to the other side

Y/N nodded to Tesseract in approval before opening a gate for the 2 Sirens back into his storage of Gates Of Nazarick. They bowed to him once more before walking back into what was essentially a sleep chamber

Y/N then opened a gate for himself onto his ship before sitting on the throne at the bridge, his daughters instantly falling into a defensive position around him in case they get attack in the Dimension Gap

"DIVE!" Y/N yelled having the massive ship turn its nose down and turn its thrusters into full speed. The ship turned into a blur as it broke the sound barrier and light barrier in its descent down to the portal

Once they entered the portal they could all see multiple clouds of colour floating in the gap between dimension "Father look!" Blake yelled as a massive red dragon could be seen in the distance, although its power was little less than Ainz new power

"Ignore it, we got more important things to do" he said as the dragon flew away in fright of the massive power signatures radiating off of the ships, it was unlike anything it had ever thought possible

After a while, the voice of Snow was heard "Portal end incoming! We will be exiting in the space above the planet Remenint in 5... 4... 3... 2... 1!"

There was a blinding flash of light that would have burnt a humans eyes from his or her sockets before all became black, in the true colour of space

"Looks like we arrived safely, all ships check-in," Raven said into the intercom. She received information from all the ships before turning back to Y/N, who was just staring down at the planet below with absolute loathing

"All ships are accounted for with only minimal damages taken" she reported, bringing a small smile to Y/Ns face

"Let the search... Begin!" He said as the ships started flying around the planet and searching for any sign of Salem

"We will find you dear, if its the last thing we do"
