"cough cough... You don't have to say turth at our faces. And Director how about you listen to my report" He changed the topic. It's true, they don't have good control over Chaldea. Even Olga thanked him mentally for saving her remaining reputation.

While they discussing, Ritsuka thought about the servants persent at Chaldea. He got information from olga memories.

Leonardo da Vinci is summoned as a servant to Chaldea. But what's shocking was "He is she". He loved his art so much, and so he became a woman named Monalisa, which is famous art created by himself.

Ritsuka felt werid.

'What beru said is true, but I hope I don't see this type of things in future.' Ritsuka fujimaru thought.

'See my Liege, I was right' Beru said while eyeing his comrades.

Ritsuka remembered what Da Vinci created in Chaldea to make herself persent in current era without a master. Da Vinci constructed a duplicate puppet of herself, and she is suspended in the present era by asserting that as her Master.

'WAIT!! PUPPET...I see'

Suddenly Ritsuka got a idea. If he talk with Da vinci and make her prepare the product. He can able to Save Olga and give her a second Life. He need to talk with her first.

Actually, Ritsuka trying to gain Resurrection skill. For that he is missing few information parts of life. He had more than enough knowledge of death but not about life. And he also need level up by fighting with strong opponents.

While Ritsuka lost in his thoughts. Olga who listened to Romani reports felt angry. She felt Goddess of Bad luck hugged her. She was happy atleast few of chaldea members are alive.

The master candidates, however, weren't so lucky, all of them have been put into cryogenic sleep and will be put into a coma until further medical assistance is available. The members of Team A in particular are all in dire conditions, with Romani unsure if their lives can be saved even with further medical assistance.

But ritsuka already know all of them are died. If some omnipotent god appeared out of no where and bring them to life then they will survive, or else they are good as died now.

" I've shifted all available manpower to repairing the rayshift system and maintaining CHALDEAS' and SHEBA's states. As soon as external communication is possible, we'll request help and supplies." Romani continued.

"...Good job, Romani, I'll give you that." Olga replied after hearing Romani's entire report. "Alright, I'll approve you as the acting director of Chaldea until I return. While you repair the rayshift system, we shall look into Singularity F." Olga declared.

"Anyway, on the account of our lack of experience and supplies, our exploration of Singularity F will be limited to finding the root cause of the singularity." Olga recomposed herself and gave the final word on the operation.

While Ritsuka felt what's going on.

'I already know the dark servants roaming in this place. Beru and Igris, both of you go and deal with them. And Also there is a caster type Rogue servant coming to meet us. So don't do anything to him. Now go' I ordered my soliders to take care those guys.

'Yes, my Liege, leave this to us.' then they disappeared from my side.

"Ohh, Where are your monster summons?" Olga asked

"I unsummoned them. I don't want to waste my Mana" I said.

"I see it's good thing. We can't waste our resources."

"Before we end communications, there is something I need to tell you all." Romani announced to the group.

"The FATE system should now be able to work." The statement made Olga widen her eyes in surprise.

"But without catalyst it will hard to summon a servant" he said.

"Even so, we can't let this opportunity go to waste. I'll send over some Saint Quartz; they are crystallizations of the concept of a heroic spirit. The RD section has been working on how to engineer them to help with the FATE system ever since Chaldea existed. It was still a work in progress." He further explained the system. Within a few seconds, 3 rainbow-colored star-shaped diamonds appeared on top of Olga's watch.

"We calculated that at least 3 Quartz were needed to summon a servant, though there is a chance that they'll just disappear into magical energy. 30 is the optimal amount, but with humanity's circumstances, I doubt the throne would be picky, so I sent 3 for Ritsuka." With that, Romani finished his mini lecture.

"Best of luck to you all. Feel free to contact me in an emergency." With that Romani cut off the communications, leaving the both of us with the crystals.

"First you should eat this food." She agreed to me. We started eat a small breakfast to keep ourselves in good mood.

I checked my mom who is in my shadow world.

And while eating we talked with each other. I become close enough to her like a good friend. I understand about her because I saw her memories. She just wants to feel love and attention. She wants to be acknowledged by others.

'I'm going to save her no matter what. Because I decided to save Olga' I was determined on this.

Then I stood and saw Olga who finished her food.

"Okay, they let's try our luck. If not let's rely on ourselves (me)" I said with 3 quarts in my hand and started ritual.

'i don't have hope in this, who will response to god of death call' I thought

"Come forth heroes of humanity, if you wish to save human order. Then come and help me" I said

Suddenly a bright light flashed and a person appeared in front of us.

"Mikon~~! Servant! Caster! Tamamo no Mae! I'm so glad to have you as my Master~!" Tamamo said

"Ohh" olga was surprised. Because she know about her but can't remember it.

Then I saw her, she had appearance of a human possessing fox characteristics. She looks cute.

Olga felt her name familiar but can't remember. But she had a strong feeling. That this servent is not a normal women.

"Oh my! My master looks so handsome" tamamo said while looking at Ritsuka fujimaru.

(Ritsuka fujimaru in this story looks like Sung jin woo with blue eyes, So of course Ritsuka looks hot.)

'Wait for real!! I summoned a servant. But from olga memories I thought Summoning a servant is impossible. Anyway something is different about her , she had a connection to a divine being. ' I thought while looking at her.

"Thanks, my name is Ritsuka fujimaru. I'm happy to work with you, Tamamo." I said and extended my hard for shake hand.

"Fufu, aren't you straight forward, master" and we did a shake hand. But when I touched her hand. Suddenly I saw connection of the source of her. And I found myself in another place.

I saw a familiar face. She appears as a large, nine-tailed being similar to Tamamo,

She saw me. For a moment our eyes contact each other. Her bloodthirsty expression changed into confused and shock.

"How?" She said one word.

Next second I saw myself again with Olga and Tamamo.

'What was that!? Did I missed Naruto anime. I saw a beautiful 9 tails fox?'

"Master, are you okay?" Tamamo said

"Yes, just thinking about what is our plan but first let me tell you the current situation." I said and started to explain the situation to her.

(Demonic temple of no return)

We can see 9 tails fox who slept with boredom on her bed, suddenly she felt some one come to her place without her permission.

She woke up and saw it was Ritsuka fujimaru. She know the famous unparalleled master across the history. She actually wanted to meet him in future and she also thought to kill all Ritsuka fujimaru from multiverse if she got chance. But she decided to watch Ritsuka journey. Now one of the Ritsuka versions from the multiverse visited her

She thought it was same situation like Hakuno Kishinami. But when she saw him, it was not the case. Her one tail didn't even form a bond with him. He came to her place by himself And what surprised her was this Ritsuka fujimaru look mature and adult version despite being young. He also looks hot and tasty. She licked her lips.

Then she was shocked because this Ritsuka fujimaru is different from every counter part of himself. Because he is death and darkness itself. He is god of death but from foreign world not from this UNIVERSE. Which makes him dangerous.

Before she can ask any questions he disappeared from her.

She got angry and released killing intent which can turn any powerful people into ashes in seconds.

"Fufufu, How Rude, sneaking into my palace without my permission and disappear infront of me."

She had a bloodthirsty expression. She wants to kill the one tail infront of Ritsuka to show how angry she is. But she stopped it, she wandering how he came to her place through space and time without creating time paradox. He must be really good in mage craft but she not liked him even if he is some powerful god in his world And on top of that.

"I don't like this at all. even this version of Ritsuka fujimaru going make that silly One tail fall for him with his stupid good behaviour".

Then She saw the future of this one tail and shocked. Because this version of Ritsuka fujimaru is different from all. He is caring and kind towards his loved ones but cold heart to his enemies.

He can go against fate and destiny to save his loved ones.

What surprised her was with each fight he continuously becoming strong.

He is the ruler of Darkness and death. If he was left alone, he will reach her level after less than 10000 years later. Well, she is now weakened.

"Fufufu, interesting. It will be fun to watch your journey, Shadow Monarch" she said. Because anyone who knows about Darkness, will never underestimate Ritsuka fujimaru, Shadow Monarch.

Shadow monarch had potential to surpass most powerful beings because...

Darkness came into existence before creation of everything is happened.

"I will be waiting for you, my dear master, Shadow Monarch. I know you will come back to me, to save your beloved pathetic one tail of mine. Hahahaha"

There is no affection in her words. But she is thrilled for their future meeting.

(Ritsuka fujimaru POV)

Olga is angry now because of Ritsuka. In few minutes he become close to Tamamo and now they became friends.

'This idiot is very good at talking with others' Olga thought.

"My, my, Master, saving humankind?

Wait, you don't think someone from my household is behind this, do you? N-No way, right?" Tamamo said and came close to her master.

"I don't think" I said. She is light hearted person.

"Fufu, I see." She said.

I was waiting for the Rogue caster servant to meet us. But it's seems like it will take some time.

'Wait I have important work' I thought

"Guys, stay here for 10 minutes. I will come back. " I said and started to move in a destroyed house.

"Where are you going?" "Where are you going, Master?" Both of them asked me at same time.

"Bathroom... Wanna join me" I said

Olga and Tamamo faces become red.

"You idiot, complete your personal work and don't waste our time. We have Important work. " Olga said by turning her head side.

"Master,...I...amm... Not ready...no...I mean I can't now ...yet... I need to check...are you...my ...fated one..." tamamo started murmur in low voice. She blushing and covered her face.

I saw her and thought. 'Did I teased her hard'

"Hey, it's a joke. Just wait here" I said and went inside the house.

Suddenly a small number of undead came near them. Olga feared and hide behind tamamo.

"Mikon~ Don't worry my master's boss. I can handle those undead. Let me show you my power. Now I'm going erase those evil things and I'm going to protect my master who is busy in bathroom" she used her power and started to defeat them.

Olga thought 'You don't have to say what your master is doing'

Meanwhile After entering the house. I cancel the Rayshift. And teleported to Da Vinci work shop. I saw the him/her who is taking care of Mash girl.

"Hmm...ahhaaaa" she surprised to see me out of nowhere.

"Sorry, about that" I said.

"Don't worry, but don't do that vanishing thing again on me. Now tell me, both you and that Monster Ant are connected" Da Vinci said.

I nodded

"I see, thank you for saving this girl" she bowed her head with respect and gratitude

"Ohh, it's okay. But I have serious matter to discuss with you."

"And what it might be" she said.

"I will be straight with you. Your director Olga life is in Danger. I want you to create a puppet body for her which can capable to store her saint graph and soul. And you will say Yes to my request" I said

"Well I am truly universal genius. So I can do that. It will take some time. But are you a Master" she said and asked me

"Yes, now I'm working under Olga but we can talk later, bye" I said and disappeared.

"Hey Wait. Just tell me who are you... He already gone. " Da Vinci said and started doing her New work.

I used same ray shift ability and teleported Singularity f.

"Fou Fou" I heard a cute voice and saw a cute rabbit type creature. But my eyes can see the truth. This creature is Dangerous but I didn't take it serious.

"When did you came behind me?"

"Fou fou" fou Said

"I see, you teleported with me."

"Fou fou fou" fou said

"It's okay, I did what I have to do. And mash is a good girl. She needs to live a normal life" Fou thanked me for saving Mash.

'Mash is popular than I thought' I thought.

Then we went to meet Olga and Tamamo outside of the house.

'My Liege, we completed the task' Igris and Beru came back to me and said.

When I saw Beru and Igris, I was surprised. Because both of them are become stronger than before.

They level up again after fighting with strong opponent

Beru got mystic eyes from Medusa alter servant after he eat her.

Olga recognised Fou. And started complain how fou came with them.

"Master" Tamamo said with serious face.

"I know, tamamo. You can came outside Rogue servant. " I said.

"Yo! Well aren't you fast, it's not like I'm trying to hide"

A voice rang throughout the area.

A blue haired man wearing a blue robe can be seen standing on the roof, in his right hand, a mage's staff is visible.

The man jumped down, approaching the teenage master and his friends.

"You're a heroic spirit, right?" Tamamo asked.

"Yeah, I'm the caster of this Holy Grail War,"

"What??? You know what happened here?" Olga asked

He nodded.

" How about we exchange information first!" I said

"Sounds good to me" he said

Then I started to explain what is Chaldea and what happened to it.

"I see." The caster said vaguely, leaning on his staff. "Your situation doesn't look the most pleasant. I'mare in no better condition, though."

"Here in the Holy Grail War I am the only survivor."

Nodding at the place that still kept the imprints of the recent battle, the man sighed and put his hand behind his head, patting his neck.

"It was an ordinary War, as much as you can say it about any Holy Grail War, but one day everything changed. All the Masters disappeared one night, then the city was engulfed in flames, and Saber..." Caster shivered slightly. "Every day that psycho becomes more and more insane. All the Servants with half a brain tried to flee from her. She beat everyone who tried to attack her. And after that they all disappeared."

Looking at the site of the recent battle, where the bodies of the Servants had already turned into black smoke, Caster frowned. "They all disappear into black smoke. These are not even Servants, just the monsters that took their form. Like worms taking the body of the deceased... And now only I remain, wandering through this fiery hellhole."

"In other words, the only one that remained in this War are you and Saber?" Animusphere, while allowing me to speak freely, still asked questions as the boss here and there. "And if you defeat her..."

"Yes, I believe the War will end." Caster sighed and ruffled his hair. "At least I think so".

"In other words". Olga sighed

" you want us to team up, right? If only so you could defeat Saber, since you don't stand a chance by yourself." Olga concluded, a slight accusatory glance sent to the servant.

"Well, that's a way to put it, but yeah. Not a bad deal, right? Our goals align after all." The mage replied, offering his hand to the director.

"We will help you to defeat saber" I said and accepted his hand.

"Haha, I like you, kid"

"Hey,... Ritsuka... Fujimaru... But I'm supposed to be the leader here" Olga had red face.

"SORRY Director, but we can't waste our time, we need to solve this problem" I said.

"Okay you are right"

"Oh, and one more thing, the source of this singularity? I'm willing to bet it's the greater grail."

"The greater grail?" The director asked.

"Yes, I suppose you could call it the true "heart" of this land." The mage explained his words further.

"That being said, Saber is guarding it, along with the remaining servants, which should be Archer, Assassin, and Berserker after the fight you guys had." He counted along the remaining corrupted servants with his fingers,

"Well we don't have to worry about them. If we didn't meet them" I said I mean my shadow soldiers already took care of them.

"Yeah, but we still need to be careful" caster said.

Again suddenly Romani call contacted us.

"Director , I have important matter to discuss with Ritsuka fujimaru." I saw Romani and Da Vinci in Screen.

I already understood what is happening by the look of Da Vinci face. She must have told about me to Chaldea staff members.

"Ritsuka fujimaru, I prepared the product, you told me to do. So, How about you tell us your intentions and yourself. You showed what humans can't do. I know you are trying to help us by supplying Mana to Chaldea. But without trust we can't move forward. " Da Vinci said.

"What Product? What you mean by that? Ritsuka fujimaru tell me what does she mean,?" Olga asked me.

"Master" tamamo worried

"Calm down every one, I know you guys will be suspicious of me and you may even think I'm behind this. But I'm not." I said to Chaldea members.

"I came to Chaldea today. Because all humans and other life forms are disappeared from outside aside Chaldea. This is the reason you guys can not able to contact outside world. I came to here to investigate. And after that you two know what happened" I said and pointed both Romani and Da Vinci. This information brought Chaos in Chaldea. They can't believe this but also they can't deny it.

" I see, it makes sense now," Da Vinci said.

Romani had serious expression because he already know this is going to happen but this happened right when Chaldea was in worst state. But now he didn't say out.

"But who are you?" Romani asked because he want to believe me.

Romani and Da Vinci don't have any hope in Team A members. So they want to believe this kid, can Ritsuka fujimaru able to save the human order.

Then I saw everyone and said

"My name is Ritsuka fujimaru..."

my eyes started to glow in purple and my body covered in purple Aura.

"...I'm the Ruler of Darkness, God of Death, the guardian of earth..."

My fake saint graph disappeared and my mana started to increase in unbelievable speed. Until Chaldea can not able to observe me. Their technology can't able to read my Black Heart.

"... I'm Shadow Monarch..."
