Alion POV

Having a spell for dimension hopping I now try sensing the resonance of the broken weapon but found nothing so praying for good luck randomly go to cracks as the pressure don't bother me now like before, then I got out to modern Era so with the cloak tangled it into a scarf covering my lower face to search for information making me meet the others which we happily exchange stories then Dr. Roman explaining the mission so we started our plan but then an alert appeared making them approach a person who introduced herself as Ryougi Shiki.

So our adventure continued as we go inside the building encountering many servants along the way in both enemy and allies which told their story along with Shiki who move on as one of them was a alter of the one I was searching making us fight her with a spear, now at the end of this singularity I bid farewell as I explain my new mission making them sad for a while but I felt we will see each other again so I give him a hug saying good luck as they started to fade after that the world slowly disintegrate which made me activate the skill and enter the portal.

Exiting the portal I came back to the void and used the item to search but found no response making me idle as to think of a plan to accelerate the mission progress when a pain assaulted me making me grab my chest in extreme pain that pushed my limit and fainting after, waking up an old cell awaited me along with Fujimaru who was happy to see me as he is scared of the place and a servant the explains where this is.

After that he guide us as we tour the prison tower encountering other servants that was helped by Fujimaru as the were release from this singularity and me watching in facination on how he done it making me smile, the known as Avenger slowly took us to the servants being embodiment of sins taking them down while he asked Fujimaru philosophical questions along with fighting them after.

Now Avenger telling his story which after we fought but with my injury(mental) became a support, defeating him something jump off into me making me faint as the last thing I saw was Edmond Dantes smiling while he fades, waking up the void greeted me confusing me if that was a dream or not but I push forward to my next destination and exit into a battle field where humans were besiege by creature inside a huge wall, summoning weapons I start the slaughter to get near the wall to ask what is happening and was brought face to face with King Gilgamesh who frown for a sec but ask my purpose here, explaining why I am here the group of Chaldean appeared from the door that was happy to see me, so I stop them to answer the king's question.

now that the city was in mortal danger he ask me to help in return he will try and give me directions to what I was looking for, taking it we fought the creatures and gorgon who has a distinct aura making me think where I knew it but being busy repelling the monsters halted this thinking which became fatal as the enemy summoned new ones using the body of the people making me fought fiercely, then the familiar aura appeared from the space crack making me freeze.

'shit' I said in my head as the huge figure appeared who destroyed my timeline, standing for a while conflicted on how to approach it when the answer came in others gives their all in repelling it from getting out so with my last remaining power summoned the sacred sword of promised victory swinging it two times before I fell on one knee drained of all my energy and struck behind by the monster but luck would have it refresh some of my powers so I hunted them down as the huge enemy was only stunned for a minute before going back to its purpose, quickly decimating the enemy mobs to recover my power and swing the sword again as the other colleagues give their all to stop tiamat.

knowing the sword might not defeat it I summoned copy of it as many as I can that I will stab tiamat sealing her movement then Gorgon appeared helping the sword stabbed in the ground from being undone, with my remaining energy scanned the stick in my hand trying to replicate it's original form which approve temporary as the battle was getting dangerous, it glowed and huge amount ether particles was drawn transforming it into a spear with it a chant appeared in my head then I said it.

"pierce the darkness so light can shine!, Rhongomyriad!" throwing it into the enemy that slowly pushed it back into a forming space crack but tiamat crouch digging to the ground to stop it with a angry roar then chains formed binding it that finished the fight as the ray of Rhongomyriad pushed her back inside and the crack slowly healed leaving me exhausted into coma with the spear going back to its default form of a small stick.

many things happened while I was asleep the few remaining people was devastated but still rebuild the city with the servants and Chaldeans helping, after the battle Gilgamesh gained a new friend Kingu and those two traveled the world in search of his purpose and enjoyment as the city was reduced into a village that not need a king, done with my time here as Gilgamesh gave a a clue I enter the portal to see where it will take me.

Babylonia after world

after going back tiamat cried in pain and sadness as she ask why this was all happening when a small figure appeared in weird attire.

'really are we truly neutral or cleaners of others' it said grumbling and look into her

'hey tia, you were supposed to die there but with him interfering the ending change so the timeline might collapse so I will give you a proposition, you come with me leaving your origin here which will fake your death to have a new life or I kill you to correct the timeline' he said as a good substance slowly envelopes him and a fierce aura more powerful than mine appeared stunning her, hard to make decision he suggested for a new life as defeating her was wrong in his gut feeling just because of the power he have doesn't mean he was evil making her accept.

a window appeared with points above and many things below it that he explained to her as she needed to buy some things for his new life as the points are only valid in this life not the next one, scrolling he got some interesting ones like unlimited random bento box, a glowing blue cube, gold bracelet, infinite page notebook to write on, daily necessities suggested by him along with protections for herself, done buying the remaining points was converted into travel world fee where she wants to go as he introduce those world to her making tiamat excited but sad as only one world will be picked so she choose random from the given ones and her spirit separated with the body and a portal appeared which she entered vanishing after, with the job done the person think smirked like a prankster for a while then took something out tossing it into a crack that appeared then he vanished leaving a dead carcass of Tiamat that slowly vanished into motes of light.
