Final fight?

prepares*Kaito PoV

We arrived at the entrance of the Cave without any problem.

with Caster staff in my hand, I scanned the inside and sure enough, Archer already waiting inside with a little girl's Signature that I presume was Rin Tohsaka.

But I don't sense Ms. Irisviel Von Einzbern and only sense some kind of container of Magic

'...It seems she already turned into a Grail Container'

"Saber Archer are inside along with little Rin Tohsaka"

"What about Irisviel ?"

"She already turned into the Grail"

"... I see" Saber did not say any word afterward and so we carefully entered the Cave

"Saber proceed with the plan we discussed earlier" I reminded her as we walking

"Leave it to me Kaito" Saber nodded

we arrived inside and the Cave is bigger than I thought, we also saw Archer, and a little girl sleeping beside a grail on some kind of Altar.

"Welcome my Dear Saber, you have made me wait too long" Archer greeted with his mocking smile

"Shall we proceed to the ceremony ?" He added

Ignoring his taunt Saber spoke

"Archer release the girl" Saber demanded

"Ignoring my word Saber? that's why you are so interesting in my eyes and release the girl? Why should I? the little mongrel should pay for the transgression her father do to me, and I have no intention to release her until she pays that debt"

'As expected talking to him is useless'

I lit my staff on fire and throw it at Archer who look bored at my attack and summoned a weapon from his gate and launched it at my thrown staff.

But he did not anticipate my staff to explode and emit a loud sound to deaf him momentarily and create a lot of smoke that also obscures his vision for a moment.

(i already cover Saber and myself with the protective rune before I do that trick)

Saber took a chance to rush forward and attempt to behead Archer with a single strike.

and I already moved to prepare my plan.

Archer jumped back and summoned his unique weapon to block Saber's attack

"so you choose to defy me again Saber? No need to worry I shall make you obedient enough to become mine"

Saber ignored Archer and continues his onslaught on Archer who keeps dodging then he shot his weapon from GoB at Saber who ignored it even as it hit her.

Saber shrugged it off and continued her attack.

Avalon instantly healed her injuries so aside from a fatal wound like a beheading Saber is essentially Immortal if she has enough Prana from me that is.

and that's why I can't use too much prana to fuel Saber in this fight.

"Hoh ? your sheath abilities are indeed intriguing and worthy to become my treasure along with you Saber"

in this plan Saber need to keep Archer only focused on her to keep Archer from unleashing his unique Weapon ability and for me to charge Gae Bolg as Plan A

"It's useless mongrel the same trick will not work on me again" Archer called out as his chains are coming out and aimed at me.

I run and the chains follow me like a homing missile as Archer is still busy defending himself from Saber's attack.

I glanced at Rin's prana level and sensed Archer started to drain it again and that means Archer already used the prana reserve that he regained after the previous fight.

'...Time for Plan B'

I dodge the said to evade the chains that aiming at my head and I slammed my palm on the ground.

The chains disappear as I activate the rune that I planted across the cave since the beginning of the fight where Saber distracts Archer with her relentless attack

The flying weapons that are aimed at Saber also disappear

'The rune that Caster based on his Teacher seems to have worked perfectly'

I commented internally as I can imagine Caster smirking when this rune worked on Archer

"What ?!" Archer is bewildered as my Rune activated and a blue rune room illuminates the cave.

Archer is distracted enough for Saber as she cut one of his arms again and loses the hand that holds the unique weapon.

He jumped back to avoid Saber from beheading him And he landed where I want.

The trap rune beneath him activated and paralyzed him in place.

"You Mongrel ?! Release me this instant !" Archer shouted in fury despite now only having a single hand again

"I am not surprised you can still talk Archer, that rune supposedly also makes the trapped unable to speak but knowing your identities you can still talk despite that. "

I approach Rin as Saber keeps an eye on Archer and ignores his words.

I carefully scanned her and found beside minor prana exhaustion she doesn't have any traps or injuries on her.

I severed her connection to Archer and create a single wood Golem to pick The Grail as I don't know what will happen if I touch it with my barehand

Ignoring Archer's insult Saber approaches him and prepares her Noble Phantasm

"Sheathed in the breath of the planet, a torrent of shining life.

Feel its wrath."

"Excalibur"!!

I watch transfixed at the beautiful light that emits from her sword and as the light died down

we watched as Archer left with a trail of gold dust signaling he is back on the throne of heroes.

I also sense Archer prana entering the grail and now the war is almost over.

and with that, I deactivate the Rune Room and Saber slowly walks to the grail and stare at it

"...So this is the end of the war and just like those from three family mages planning, the grail will not activate unless all Servants dead and fuel it," Saber said bitterly as she look at the Grail that is formerly Ms. Irisviel von Einzbern

"So you do indeed also deceive me from the start Irisviel," Said Saber with a tone of sadness in her voice as she witnessed it herself

And before I can respond to her words I sensed something in the grail and only feel one thing

*DREAD*

"What is this ?" I shuddered at the feeling from the grail emitted and Saber seem also notice it because she immediately move between me and the grail. and I also have a bad feeling about the grail decided to give Little Rin to the golem instead and command it to run back to the church that I give it the location in its mind.

I planned to scan the Grail to find the cause for such dread feeling

"Stand Back Kaito, there is something dangerous on the Grail-!"

Then at that moment, the Grail spewed out black mud and swallowed us. and before it happens I manage to give an extra command to my wood golem.

*Protect Sakura Matou*
