Poseidon Pov

Dashing at Achilles I stabbed my Trident at him, he smiled and with an equal speed he deflected my attack, I quickly dodged some arrows shot at me by Atalanta, she wasn't using her trump card like the original so my current circumstances were better, I continued fighting with Achilles who displayed an equal amount of agility like me, his swiftness was more than me but my experience in using Trident made me calmly fight against both of their attacks simultaneously.

"As expected of you Lord Poseidon, being able to keep my speed and considering my vessel is currently able to display 100% of my speed Parameter's wise it is impressive", he said praising me wholeheartedly with respect and admiration, I ignored him and destroying all the arrows shot at me by Atalanta, I performed dozens of stab at sound breaking speed, his eyes widened seeing this.

The next moment he was meters away with a serious look on his face," I see, I have been disrespectful to you by not going all out, very well I will give my all!", he said as his body shone lightly in the green light,' Here it comes ', I thought getting ready to fight him, Achilles used his Noble Phantasm Dromeus Kometes, his speed instantly quadrupled as he dashed at me.

I covered my whole body doubling my all Parameters and swiftly blocked his stab, he smiled and continued doing stabs at me, I blocked them and grinned, I started doing stabs at him, and while his movement was twice as fast I easily managed to stand against his rapid stabs and responded with the same, meanwhile Atalanta had stopped shooting her arrows and watched us as we fought against each other.

I did a powerful parry with my trident and managed to throw him a few meters away, he quickly moved to regain his balance, and circling me he managed to get behind me and stabbed me with his lance, I calmly blocked it using my trident without even looking back and threw him away, he again circled me and moved so fast that a tornado formed.

" I will win this!!", he shouted running around me, the next moment dozens of his after-mirages covered me while all of them stabbed at me,' Not bad, he managed to make a half-ass copy of my technique after seeing my own, but well ', I thought and used my strongest technique Medusa Alope Demeter, and I got behind all of his afterimages, he looked back in surprise and the next moment he was greeted by hundreds of my after mirages stabbing at him.

His face looked at me stunned as my Trident ripped his body with countless holes, "Ahhhh!", he cried in pain as our battle ended, blood spewing out of deep holes in his flesh, he looked at me gobsmacked," Your half-ass cheap copy didn't stand a chance against the real deal", I said calmly glancing at Atalanta who looked at me with her angry eyes.

He started laughing and said," Hahaha, Even short that was the hardest battle I ever had and I feel pride that I stood against you, even if to lost", he glanced at Atalanta who aimed her arrows at me," Missy, it seems I failed this time making you my wife, but fret not I know we will meet in future".

She grunted and said," Who wanna meet you again Bastard?! Just die already!", Achilles laughed and she snorted though if one were to see in her eyes one could see a bit of reluctance and sadness,"-Auckk!", she coughed blood surprised as my Trident pierced her, this surprised both of them confused by what happened, it is simple I didn't waste my time and using my immense speed I stabbed her while distracted, truly an idiot she is.

" It would seem your flirting didn't go to waste Achilles", I said amused, Achilles started laughing while Atalanta glared at me and said," Fuck you two", Achilles turned into golden particles vanishing, and I took my trident out of her chest, she fell on the ground and her body started vanishing as well.

I am unsummoned my Trident and quickly moved toward the Throne room, entering I was welcomed by the scene of the separated head of Serimanis whose body started vanishing and a fatally injured and poisoned Mordred on her last leg, I quickly approached her ready to detoxify the poison and save her but she stopped me.

" I think it's my time to leave", she said with a smile, I asked her," Not wanna fight for Holy Grail?", she smiled bitterly and said," I am content especially after killing that bitch, also what's the use of staying here? You bastard will win anyway", a creepy smile came on my face scaring the hell out of her," Wha-What's with that smile?!", she asked crept out.

" Don't ever, USE BASTARD WORD TO CALL ME AGAIN, get it? otherwise, I will call you a bitch", I said smiling, she nodded frantically and said," You know what, I will refrain from calling you from Ba- I mean that and you won't call me a Bitch!", I nodded, and standing up I said," Well, it was nice meeting you son of King Arthur, Knight of Betrayal, the legends about you did forget to tell one thing".

I stopped saying any further and turning around I started leaving," Hey! Mister God at least tell me what was that thing!", she shouted and I continued walking away ignoring her," Tsk, truly a troublesome God", it was the last thing I heard from her before I left the place breaking the sound barrier.

"Tsk, tsk, at least he could have told me what that one thing was", said Mordred pouting,' Do you feel regret Saber? ', Kairi sent a telepathic Message, smiled closing her eyes, and replied,' I don't feel regret Master, it's just ', she opened her eyes and finished," He is similar to my father, even if it's just a little bit", her body started vanishing until not a single speck of her existence remained.

Kairi on the other hand in the Aircraft sighed and looked at the last Command Spell on his hand," It was truly an honor fighting with him", his face softened remembering her daughter and he smiled," You make me remember her as well", he said while clenching his fists.

Poseidon Pov

I entered to see a distraught Jeanne and William Shakespeare with Gilles summoned as Saber, this idiot managed to summon him as Saber after he abused Holy Grails another mechanization, though Gilles is extremely weak reduced to the level of a low-level servant as a result, I glanced at them and walked towards her.

" Oh! So she is the God you have fallen for my Jeanne! What a heinous sin! By doing so you betrayed the Lord!", Gilles said dramatically as she trembled, I looked at the two jokers and not waiting any further I stabbed William through the chest,"*Puff*", he coughed saliva looking at me shocked," At-Atleast you should have- le-me finish my pla-y", his eyes became hollow as his body started vanishing, truly a low-level servant.

Then I made quick work of Gilles as well while Jeanne was sulking not caring about what is happening, finally finished I looked at her and sighed, a person can be strong-willed and weak at the same time, and undoubtedly William as a writer knows this, with his intellect, he somehow managed to make her end up in this state.

Tears streamed down her cheek, I made myself at her level and grabbed her cheek, she looked at me with teary eyes and said," Lo- Poseidon, am? Am I right? I-I betrayed my God, do- you love me?", her words barely made sense which made me realize that this time William went further than he did in the original.

I sighed and flicked my finger on her forehead, she grabbed her head in pain while looking at me pitifully, I stood up and said," Being right or wrong is subjective, What defines that you are right? What makes you wrong? Just because you think you are right makes you right? Do you think you are wrong just because others said so? See it is hard".

She looked at me with full attention, her purple eyes glistened as she went ahead and grabbed my hand, bringing it to forth her tear-stained cheek, she closed her eyes and asked me," What do you think Poseidon? Was I wrong?", I ruffled her bright blonde hair and said," You truly an idiot Jeanne, to not know about yourself, but yes I consider you are right".

Her purple eyes looked at me with warmth, and she replied," I see, I am truly an Idiot", suddenly clapping sounds reached my ears, not surprised I turned back to see Shirou," A Holy Virgin falling in love with a Greek God, it is something that I even haven't thought in my dreams", he said with a smile on his face, I looked at him uninterested and said," You will die here Shirou, all your servants are dead including Serimanis".

His eyes narrowed upon hearing that then returned to normal," Indeed you are right, but before that", he turned towards Jeanne," Will you join in my goal of salvation Ruler?", Jeanne replied firmly," I won't! Your approach, your method, your goal! Is something that goes against humankind and till the end, I will stand against you and your goal!".

" So a No huh?... But let me ask you Ruler, what about your act of falling in love? Didn't you give your entire self to Lord? Even falling in love would be counted a sin much less falling in love with another God", he said, Jeanne gripped her flag tightly before taking a deep breath and said," I have sinned the moment since I have held this flag, by now I don't care about it anymore".

Shirou's eyes narrowed upon hearing that and he said," Truly, You are a hypocrite!", I moved forward with the intent to finish this bastard off not wanting to hear his rants anymore but Jeanne stopped me holding my hand gently and looked at me, her face started turning into a shade of red as her lips moved," Please, le- Let me... Let me Protect you this time!", with her face flushed she looked at me anticipation.

I smiled and said," Then go ahead and protect me Jeanne", a big beautiful smile appeared on her face, Shirou grunted taking a battle stance, and shouted," Stop flirting in front of me, bastards!!", he dashed attacking us, Jeanne quickly parried an attack from his sword with her Holy fag and then said, "La Pucelle!", fire manifested around her.

The battle between her and Shirou raged on in a similar way to the original, as I watched carefully with my eyes as the battle unfolded before me ending with Shirou being severely injured and Jeanne losing, I quickly took her weak body laying on the rubble in my arms, she looked at me and grabbed my hand," You haven't told me yet, Lord Poseidon do you love me?".

I replied," I like you Jeanne, but no, I don't love you", my cruel words struck her heart, and tears came out from the corner of her eyes, "Ca-Can I know why?", she asked me brokenhearted I sighed and said ruffling her hair," Cost of loving me isn't something you can bear", her eyes widened hearing that, I continued," There are many things I don't accept about you, and again there are many things I like about you, it's my own selfishness, I can't accept you someone like you".

"I see...", she said as her body turned into particles revealing the backup body of Laeticia who was unconscious, I heard a laughing sound and turned to see Shirou standing up, his one hand good as gone, he spits out his two broken teeth and said," That was some unexpected Drama", next moment I appeared near him and pierced his core with my trident.

He looked at me with a weak smile," It's useless... I have won and it can't be stopped... My only regret is I won't be able to see it with my own eye-" Before he could say anything further I separated his head with my sword, I looked at the brightly shining Greater Grail threatening and started walking towards it.

"Lord Poseidon!", said Laeticia, without looking back I said," Stay there for a bit, I will come to fetch you shortly", then I went inside the Greater Grail not wasting time any further. Coming Inside I was greeted by a flower field and a woman with Long White Hair, she was none other than Justeaze Lizrich von Einzbern, a human and user of the Third True Magic and she was the person whom the Homunculi of Ainzbern are based on.

[Ding! You have won the Holy Grail! Please Choose a Wish!

1) Attain Third True Magic

Advantages: Extremely Pure Mana, Soul Manipulation, Soul Immortality, Extremely fast Mana Regeneration.

Disadvantages: As you are not directly attaining it from the Root and due to your unsuitability for it won't fuse with your soul Nuclei using your soul as a medium to work instead, can result in tremendous pressure on the Soul. Can result in the destruction of the soul if overused.

2nd) Wish anything you like, the Holy Grail will achieve it within its limitations.

Advantages: You will get what you want.

Disadvantages: Worse than Third True Magic, wishes won't be perfectly what you want, you can't wish for the power of any other verse.

3rd) Use Holy Grail to get a well-suited reward by the system.

Advantages: You will get what you need.

Disadvantages: You can't wish for anything and you won't get anything specifically you wanted. Your reward won't have any nerf or other disadvantages, it will be simply made for you]

My eyebrows twitched seeing the best option among them has too many disadvantages, I angrily asked,' System are you trying to control me? Make me depend on yourself? This option seems to limit my strength ', I narrowed my eyes.

(A/N: He is not wrong, but it is me who is doing that not the System)

[Master! I am just giving you the answer to what will happen if you choose any of these and what will be the consequences, your reward will be decided by you, in fact with all your merits you can even erase their disadvantages, but Third True Magic is too powerful that, I calculate if you were to get five times more what you have now by earning merits I can erase the disadvantage of the magic, also it can't grow any further under normal circumstances, you will hit a bottleneck with it in future and would have to do something else to make it grow], system replied.

I sighed, taking a breath, then I asked,' My rewards for the merits I have earned till now and Holy Grail are different right?'.

System replied[Yes Master].

I said,' I choose the third option '.

[Ding! You have been bestowed a reward!], the system said as the entire Greater Grail was sucked into nothingness making me teleport outside of it.

[You have got a Mana Heart: EX(Growth Type)

Functions: Absorbs Mana from the surrounding rapidly and then pumps them into your body as several times purer Mana in your blood.

Advantages: Act as a reservoir of Mana increasing Mana capacity, it regenerates Mana rapidly, its current speed is about 100 times the Mana regeneration of a Normal Peak Human from Age of Gods, also due to its ability to absorb Mana from the atmosphere makes you independent of a Master, unlike other servants. If damaged or destroyed it can regenerate itself entirely though the speed of regeneration is very slow and may take several days to completely regenerate.

Disadvantages: You will lose Mana stored in it and all of its Mana absorption if destroyed, the above-mentioned effects are severely weakened when damaged.], System said.

My eyes opened wide seeing the reward, I smiled seeing this, well I guess it's still good, heck better than what I anticipated. Still, forcing my excitement down I looked back and saw Laeticia who seemed afraid of the breaking rubble showering slowly, I knew that Hanging Gardens of Babylon isn't gonna last long so I quickly grabbed her in a princess carry surprising her.

Then I quickly cast a fly spell and started escaping from here, some broken rubble fell on me but I easily destroyed them and successfully came out, Laeticia gripped my neck tightly scared of the height," Don't be scared", I said and she nodded, then I flew towards the Airplane, yes the plane has been flying behind Hanging Gardens of Babylon two kilometers behind.

I approached it flying, and then looked through the window signaling them to open the door and then came inside, I was greeted by Clauses, Fiore, and Kairi," I have won and stopped them", I said making them breathe in relief, Fiore asked me," Lord Poseidon what was your wish?".

I put Laeticia down who said blushing," Thank you!", and then turned at them who sweated and replied," Purer Mana", they became dumbstruck hearing me, Kairi asked me in disbelief," Just that?!!", I nodded and said," Holy Grail's mana is as pure what I had while as God", they gasped in shock.

(A/N: He is referring to his other self in Fate, and worded his words with double meaning, so yeah he didn't lie, as for why he refused to tell them, simply he isn't that big of a jerk to who helped him, even if it's a little)

"Ah, I- I see, I forgot you were a powerful God", said Fiore shocked, I patted Laeticia who seemed down, and then looking at them I said," Can you do a favor and please escort her to her home", they looked surprised seeing me using the word please, I mean I just didn't want to jerk when I needed help.

"Sure, don't worry about Lord Poseidon", said Fiore, I smiled as my body started disappearing, Laeticia hugged me taking me by surprise, I looked at her face stained with tears and sighed' Not again ', I thought," What about Lady Jeanne?", she asked me, I replied," It depends on fate", she then hugged my vanishing self tighter and said," Thankyou".

I said," You know, you might find someone else who would truly love you", she looked at me surprised, I smiled ruffling her hair, and vanished from this world.

...

3rd Pov

"Yes, I may find someone who might truly love me, but would my heart love that someone?", Jeanne muttered sadly.

To be continued...

(Author's Note: Apocrypha arc ends here, also to not ruin your sleep, Jeanne will be in harem, and this specific one, no other her of different timeline as for Laeticia, still unsure but please be patient and not be childish, I am not the one to go for sad ending)
