A Not So Evil God In Fate/Grand Order

After the charade was over. Cu looked at Seth smiling a bit. "So you managed to beat Berserker eh? I knew you had it on ya!" It would be a lie to say he wasn't worried -not that he would say it- but seeing him in one piece relieved him a bit. Although he didn't expect Seth to win without sustaining any injuries.

Seth closed his eyes and grabbed the back of his head. "It wasn't easy, I nearly died a couple of times. Plus, he threw me around like a ragdoll and almost chopped me in two." Just remembering that fight gave him a headache.

Caster raised an eyebrow at his words. "You look fine to me." he said. And indeed, if one looked at Seth's body. They would think of him as the epitome of health.

"I just healed myself with the help of my weapon. I don't have any external or internal injuries but I can't do anything about the pain." It hurt like hell but it was nothing he couldn't handle.

Olga, being ignored, couldn't help but interrupt their chat.

"Wait a minute! I need to question you about how is it that you got here! But first of all, have some shame and cover your c.h.e.s.t!" She shouted indignantly.

Seth could feel a headache incoming. "Listen, kid. This is the only thing I have with me right now and besides, I don't remember ever becoming your subordinate. I don't think you can order me around."

Olga's face went red, from embarrassment or anger, that was unknown. "Listen here you stri-.." She was about to continue before being interrupted by Roman.

"It's okay, Director. Calm down a little, we won't be getting anywhere fighting like this." He tried to reason with her. Fortunately, it worked.

Taking a long deep breath, she sighed. "You are right Romani, there are more pressing matters at hand."

She then looked at the Caster servant who was on the sidelines enjoying the show. "What do you think we should do to stop this, Caster?" She hated asking other people for help -except Lev- but giving the circ.u.mstances, she didn't have a choice.

"Well, for starters, we should kill the remaining Shadow Servants before facing Saber. We have defeated Assassin and Lancer, Se-...he defeated Berserker, there are only 2 Servants remaining, Rider and Archer. I don't know the location of Rider, but Archer is going to be wherever Saber is. We share mutual interests so we should fight together until all of this is over." Caster stated concisely, avoiding calling Seth by his name.

"Makes sense. But if we do that, who will be your master? Him?" She pointed at Seth.

Caster shook his head. "That kid there, of course. It doesn't seem like you have the aptitude to be a Master. And him? well, he is a special case so I don't think it would work." He didn't forget to add salt to the wound though, "You have top magic circuits but not the aptitude to be a Master, is it a curse? Tough luck there, young lady."

"Oh shut up! Why do you care?" She exclaimed. That was a sore spot for her.

Despite remaining silent, Olga could see how much the stripper guy was enjoying her misfortune (He definitely was).

Turning to the Master she said, "He is in your hands, Fujimaru. Make sure to use him well."

After everything was over. Caster looked at his new Master. "Then it's settled. The contract is only temporary, but I'm counting on ya."

Fujimaru just smiled. "Hm. Even tho I don't quite follow everything that's going on, let's work hard together." (A/N: Shounen protagonist aura is strong with this one.)

"Well, with that out of the way, what you are probably looking for is the Greater Grail." Caster said making the trio and doctor confused.

"Greater Grail? What is it?" Dr. Roman asked. To which Caster replied, "It's this land's true "heart", that would be what you are looking for. The thing is, Saber is around it. If you want to get it, you will have to defeat her."

"I see. Mister Caster, please lead the way" Roman said causing an exasperating sigh to drop from Cu's lips.

"Drop the 'Mister'. I will lead you there, but the kid will decide when to make a move." Caster said and then looked at Seth. Which at this point had faded into the background. "You are okay with that right?" "Yeah, I don't have any problems."

After confirming their target, they departed.

=========================

Currently, they were taking a detour. Apparently, the servant with the shield was depressed because she couldn't unleash her Noble Phantasm. A Noble Phantasm is the embodiment of a legend belonging to a Heroic Spirit, the fact this girl couldn't use it puzzled Seth but he ignored it. Not his problem, he thought.

Caster said he was going to help her unleash it. After all, having half the war potential is like having none at all. He started by adding misfortune runes on the annoying kid's coat. 'Nice one, Cu Chulainn. I knew you were someone I could trust!' Seth gave a mental thumbs up to the man.

Not long after, a horde of skeletons appeared before them. He decided to stay in the sidelines like Cu and let the shield girl solve everything herself. Otherwise, she won't accomplish anything.

The Servant girl raised her shield to meet her enemies. "D-Director, get behind me! You too Senpai, prepare for battle!"

'Her personality is fit for a shield, at least.' He thought after seeing her actions.

This time, Caster spoke, "To put it simply, a Noble Phantasm is part of a Heroic Spirit's instinct. It's hard to use it if you think too much. Therefore, you must first use up all of your energy,

young lady! Man, I'm a genius!" Caster laughed feeling a little proud inside.

The trio fought with all they've got. The Servant slamming her shield onto the skeletons, the annoying kid providing support with her magic and occasionally attacking while the Master just gave the orders -if a little clumsily-.

"I can't, go on——Any more back-to-back, battles——I'm sorry, Caster——" The Servant spoke between breaths. It seemed she exhausted all her energy.

Did Caster seem...disappointed? He couldn't tell. But he was sure he wasn't pleased his plan didn't work. Gone was now his playful attitude, now he was serious. The only time Seth remembered Cu like this was when he told him about Saber and Berserker.

"You just don't get it, do you? It seems I must kill your Master to see if you can unleash it." Caster spoke while rising his staff.

"...!" Mash's eyes widened at Caster's words

"What are you talking about? Are you crazy? What does Fujimaru have to do with this?" Olga asked, feeling a little fearful, but most of all, angry.

"A Master and a Servant share the same fate. If one dies, the other is next. That simple" Caster stated. Damn, he got acting skills. Seth thought while watching the event unfold.

"Master please get behind me, I...I won't be a hindrance to Senpai!" She exclaimed, determination oozing from her.

"That's what I wanted to hear! Now, let's have a real Servant battle!" Cu shouted while raising his staff and preparing to chant.

======================

They have been fighting for over 10 minutes, considering how tired the girl was after fighting the group of skeletons, it was impressive. That and Caster wasn't serious, even if he looked that way.

Suddenly, magical energy started gathering around Caster. 'So he is using it huh?' Seth watched as Cu Chulainn was preparing to unleash his Noble Phantasm. He was curious he's got to admit. Everyone he has fought so far had only been Shadow Servants, incapable of using their Noble Phantasm. This was the first time he was going to see one.

His eyes focused as much as he could on Cu, hoping to learn something. To possess a Noble Phantasm, he had to be a Heroic Spirit. But, if he could find a way to bypass this requirement, he would be able to unleash his various legends in the form of mysteries and even a Noble Phantasm. (A/N: Think of it like Merlin's case, the d*ck wizard -Who never bothers to show up in my Chaldea btw- possesses the qualities of a Heroic Spirit even tho he is still alive.)

«My spell is the coffin of flames, a giant of verdant thorn.

Retribution, the forest that will purify human misery—

Befall the Wicker Man!

And behold. as both good and evil bite the dust——!»

Flames covered the already hellish place. From the ground, A wooden arm shot towards the sky, followed by the rest of the body. What appeared before them was a giant made out of good. Caster commanded it to go forwards, with each step it took, the earth trembled.

'It's power is amazing.' Seth thought while looking at the giant

As Caster Noble Phantasm was approaching, Mash started to panic.

"I must protect... I must unleash it, or everyone will——

Even if it's fake, even if it's just for now...l have to unleash it properly, or everyone will

disappear——!" Ever so slowly, determination was showing on her face.

"Ahhhhh!!!" With a final shout, a big, green magical shield former on top of her, stoping the punch that was coming from Wicker Man, Caster's Noble Phantasm. Seth, who was watching the girl attentively, closed his eyes. A smile forming on his mind. 'So that's how it is...'

Watching Cu unleash his Noble Phantasm has been helpful to figure out how to create his own. But watching the girl do it was even more so. After all, it was simpler to watch a student learning how to solve a math problem, than the teacher resolving it without explaining anything.

Caster told him the real identity of Saber. The King of Knights, Arturia Pendragon. He was a bit surprised knowing she was a girl, but the situation didn't improve even if they knew her true name. At least, not then...but now, things changed. While Seth couldn't form a Noble Phantasm yet even if he had the ability to do so. Watching the girl forming her Shield, he managed to make something. Make something like Cu's Protection from arrows...the information appearing in his mind like some sort of magical thing.

This was starting to get interesting.
