A Not So Evil God In Fate/Grand Order

Seth and Caster were sitting together on top of a building. Seth was looking ahead bored out of his mind while Caster just rested his head on top of his arms looking at the sky.

"Now that I think about it. I've never asked your name" Seth said while casting a sidelong glance at Caster. Said man just raised an eyebrow but then sighed. He remembered this guy is clueless.

"Saying our true name is kind of like a taboo, ya know?" Caster said while still looking at the sky.

"Why? Is your name a girlish one?" Seth asked the blue guy.

Now it was Caster's time to want to punch him. "Idiot. It's nothing like that, saying our true name will reveal our weakness if another Heroic Spirit knows who you are, then he can prepare to counter your abilities" Overlooking the insult, Seth understood now why would he want to keep his name a secret.

"Anyway, it's not like this is a normal Holy Grail War either, and if we wanted each other dead we had thousands of opportunities to kill one another. The fact we are still alive means I don't want to kill you and you don't want to kill me" Caster said to which Seth agreed.

Getting up and removing the dust from his clothes Caster looked at him. "My name is Cu Chulainn. The Hound of Ulster. Although I would've liked to be summoned as a lancer, I will try to make the most of it as a Caster" Former Caster, now Cu Chulainn told him his true name. Just like that.

Seth's eyes flashed with surprise but in his mind, he smiled wrily. 'I guess he trusts me more than he lets on' He closed his eyes for a moment, before opening them and looking at Cu Chulainn. "So you are the user of Gae Bolg? That's surprising. My name is Seth. I'm what you folks would call a Divine Spirit, tho I'm not so Divine at the moment"

Cu's eyes opened wide. A Divine Spirit? How is that possible? Has the world become this messed up? "A Divine Spirit you say? That's impossible! It's been a couple of thousand years since one manifested in the world as far as I'm aware. And wait a minute, did you just say you were Seth? Like, that Seth? The one who killed his brother?" To say Cu was surprised would be an understatement. He didn't like troublesome things, he just wanted to have a good battle and nothing else. Now he was stuck in a War that got messed up and in the company of a psychopath who killed his brother! Despite having D luck in his parameter instead of the E of his lancer counterpart, it seemed bad luck always followed him.

Seth, for his part, just sighed seeing his reaction. It was always like this when someone knew his identity. "Yes, I'm him. Don't worry, history is always written by humans, you never know what really happened"

"So you didn't kill and mutilate your brother?" Caster asked calming a little.

"No no, that part is one hundred percent accurate." Said said. Cu just fell comically to the ground. Ignoring his antics he continued. "As for the part about me being able to manifest here, it's because my divinity got sealed to the point I look like a human, just a little stronger. Besides, I'm not the Seth of this world, for all I know, he might be dead. I'm just a God from a parallel world to this one" He finished making Cu a little dizzy with all the information.

Cu put his hands on top of his staff and rested his head on them. At this point, he was just too shocked to show a reaction anymore. "That for once explains why you can manifest but not why you did it." Cu said but added "Well, forget it. It will add troublesome things to my already troubled head and I doubt you would tell me even if I asked"

Seth agreed with this. All it was going to do was get things more complicated. After standing up he looked at Cu and asked. "Do you know which of the other six Heroic Spirits excluding Archer is strong?"

Cu seemed taken aback but the question but he still answered. "Well man, if I have to be honest I would say the only Heroic Spirits worthy of a fight would be Berserker and Saber. Berserker, even tho he lost to Saber and became that shadow-like thing. It's still strong enough to wipe the floor with almost all the others even if they didn't lose their Noble Phantasms after becoming a shadow" Cu said after contemplating for a bit.

"Do you know where any of those are?" He asked again. Hoping he would give him a satisfactory answer, and he didn't disappoint.

"If we are talking about Berserker then he is in the forest surrounding the city. He keeps roaring and roaring so if you get close enough you will know his exact location" Cu said while flashing a smirk. It seemed he was not the only battle-hungry one.

"What about Saber?" Seth asked after processing Cu's information.

The air around the Caster suddenly became deadly still. There was an atmosphere of seriousness that wasn't there before. Even Seth was surprised at this.

"Forget about Saber, trust me. I don't know how strong you are but she is on another level" Cu said while giving the only rational advice when it came to that monster.

Seth crossed his arms and looked at Cu for a second before asking the question he was dying to know. "Is she that strong?"

"Yeah, you are probably going to fight Berserker right now, aren't you?" Cu asked, Seth just nodded. "Then let me tell you this, even when Berserker was at his peak with Noble Phantasm and all she still could beat him. I'm not saying it was a walk in the park. But the fact remains, she won and Berserker lost"

Suddenly, as if nothing had happened, the atmosphere returned to normal. Caster just scratched the back of his head. "Look, if you fight Berserker and win with ease, you may have a chance against her now that she is not at her best after their fight. Otherwise, forget it" This was the only thing he could say to him.

"I understand, but what about you? What are you going to do now?" He didn't think Cu would accompany him to fight Berserker. When it comes to having a battle, they were like-minded people. They didn't like the idea of ganging up on someone. A fair duel where you put everything you've got is what they wanted.

And sure enough. "I'm just going to try and find some Servants to kick their asses and see if I can thin out the competition." Caster said while looking at the giant bridge in the distance. Seth followed his gaze before asking. "Did you find anything?" to which Cu just gave a simple nod, smiling like he was anticipating something.

Seth just turned around and started walking in the direction of the forest but was stopped but a shout of Cu Chulainn. "Hey, take this." He said before throwing a stone that was giving a faint blue light. Catching the stone Seth looked at Cu questioningly. "I engraved some runes in that stone. It will lead you to my general direction. If you come alive after your fight with Berserker be sure to use it to find me"

Seth just nodded. "Will do"

With nothing more to say, they went their respective ways.

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

After walking for half an hour. Seth finally heard what he wanted to hear, a roar. Increasing his pace. Killing the occasional skeleton he came across, he finally stopped when he stood before what looked like a giant monster. Even tho his features were covered by the shadow, it didn't diminish his fear-striking appearance.

Berserker was almost double his size, he was carrying a stone Axe-Sword. It was a brutish sword, more like a lump of rock than an axe. Even if Seth couldn't see his face. He knew Berserker was piercing him with his maddened eyes, ready to strike him at any moment.

Pointing his spear at the giant warrior he spoke, knowing perfectly well he wouldn't respond or even understand. "Let's see who will be standing at the end, will it be you? or will it be me? let's find out, big guy." The response he got was a roar, not that he would get anything else.

Seth inclined his body to dash forward. What he didn't expect was for Berserker to suddenly disappear. His eyes widened a bit. 'Fast!' Almost on instinct, he grabbed his spear with both hands and raised it to his left side, where a stone sword of Berserker was heading to.

But, reality is often disappointing. As if to mock him from his words earlier, he was sent flying. Like his resistance meant nothing at all.

*Cough cough*

Seth threw the debris on top of him, getting up he coughed some blood into the ground. 'You've got to be kidding me. What's with that physical strength' he complained while reappearing on the streets where Berserker awaited him.

His arms were shaking a little after he "blocked" Berserker's swing. 'Strength will not work, not against him at least. I need to evade each one of his attacks. But even that will prove difficult, not only his strength is high, his speed is nothing to scoff at either'

After seeing him back up, Berserker, flexing his leg muscles making the earth beneath him crack, made a high jump and then came crashing down at Seth.

Having learned his lesson. Seth jumped to the side avoiding Berserker's hit. This didn't stop the shockwave from sending him further from his original position.

This continued for several minutes with Berserker being the only one attacking. However, experienced eyes would be able to tell that with each passing moment Seth was starting to get used to Berserker's fighting style, no, that's not quite right either. He wasn't just getting used to Berserker's fighting style. He was copying it!

Even tho Berserker's fighting style didn't suit a spear user, his agile movements were truly appreciated. Seth wasn't aware of what he was doing. After all, his full concentration was on the fight.

Suddenly, his ever so red eyes partially changed to gold for a moment. But at that moment, Seth evaded a swing from Berserker and did a vertical thrust against his b.a.r.e torso, creating a line that made blood flow out from him.

Silence, total silence. For a second, both maintained their position as well as their stances. A second later both separated. Seth looked at his hands while Berserker looked at his wound.

"haha...Haha...HAHAHAHAHAHAHA" His cold facade crumbled, replacing his face void of emotions was a hearty laugh. He couldn't help it. How long has it been since the last time he enjoyed a fight like this? where the odds were against him? were death was around the corner? For a moment, he forgot all his troubles, all his past, all his worries. He just concentrated in the foe before him, who was even through his shadow veil, Seth could see the anger in his eyes.

"It's time for round two, BERSERKER!" He exclaimed with enthusiasm, ready to face his enemy one last time.

Meanwhile, on the side of Cu Chulainn, he was looking at the battle unfolding in front of him. Shadow Assassin was persecuting a group of people he didn't know. There was one clueless guy, who, if his vision didn't fail him, was a Master if the Command Spells on his hands was anything to go by. A pink-haired girl carrying a big shield with her. The last was a white-haired woman who appeared to be a Magus.

He watched as Assassin put the trio into a corner only for Lancer to show up too, making things even more difficult for them. The white-haired girl panicked seeing a second Servant appear. 'Man...seeing little girls making that kind of expressions isn't to my liking' Cu said in his mind while he continued to watch. Even tho he would have to eliminate those servants eventually, he wasn't a charity. He wouldn't help them out of the good of his heart, especially if they just run cowardly in fear.

At first, he was going to give up on them. They were just frozen in fear. But then, against all thinking, the Master decided they had to fight to have a small chance of survival. Although little Magus girl was against the idea, the Servant backed his master.

"We must fight. I will find a way for us to get out of this alive!" The Servant girl said with determination. Cu just smiled, this was what he wanted to see.

As Assassin jumped towards the Master, I chanted a quick fireball and sent it directly to his face. 'Ha. Servers you right' Cu said in his mind.

"I thought you were just some girl, but it looks like you've got some fight in you. Then I can't leave you like this." He said as he appeared before the group of Shadow Servants and the strange trio.

Tonight, there will be two Servants less in this cursed Grail War.
