Arc 1 - Chapter 1: Well, I'm Alive

(Unknown Cave)

For some unknown reason. I have mixed memories of the same person, which is myself, but with a different beginning and ending even the afterlife. Talk about weird, but then again, being living, breathing, [Heroic Spirit] is already considered weird itself.

Of course, I can just think it as my E Rank luck is part of the reason why I'm in this situation or something. No clue if being alive again is, well, a bad thing, but knowing my luck and like the other alternative version of myself.

I, Cú Chulainn, formerly known as Setanta, have somehow gained a new life, and furthermore, I seem to have all my counterpart, skills, magecraft, even the battle gear, and Gae Bolg.

Yeah, I seem to be able to create multiple copies of Gae Bolg, which is cool and all, but completely weird for me. Seeing how most of the mixed memories I have; well, the alternative of me would only wield a single Gae Bolg only.

But, who am I to give up this advantage. Save me the effort of having to deal with the chance of Gae Bolg being stolen, destroyed, or just lost it somewhere, and have to figure a way to get a new one or find the old one.

Either way, with all these mixed memories I gained from the [Heroic Spirit: Cú Chulainn].

I would have to say. Yikes.

Out of all the different versions of Cú Chulainn. He literally has the worst luck ever and end up getting killed without giving the chances to use all his strength. Like seriously, most of the timeline related to the Fifth Holy Grail War.

Cú Chulainn was either forced to fight without able to finish off the enemy or use everything he has to kill the enemy Servant.

Heck, even I can tell that Cú Chulainn is a monster in his own right, but due to his bad luck, which I know for sure I would have the same luck as well, Cú Chulainn continues to die in the most tragic way and a very selected alternate version of Cú Chulainn managed to defeat all the enemy servants on his own, but still end up getting kill somehow by an unknown factor like a hidden servant from the previous Holy Grail War or something he can't remember exactly, but killed him the very last moment he killed the last servant.

Yeah, that's right. I got one of the memories of Cú Chulainn, who manage to solely kill Berserker, otherwise known as Heracles the greatest hero in Greek mythology. A fellow demigod as Cú Chulainn.

Also, not the mention in tales of Cú Chulainn, where he continues to fight an army by himself while his strength is weakening due to breaking multiple oaths that the enemies forced Cú Chulainn to break. In the result of Cú Chulainn having to fight his last battle while not being at full strength. Talk about a monster in his own right.

As for me, I got the version of Cú Chulainn, be it the Lancer-class, Caster-class, and even the Berserker Alter-class, memories, experiences, and everything.

Making me feel like the strongest Cú Chulainn at the moment. Due to the fact that I have all my alternative version's abilities to use, not to mention I could feel my prana being a hundred times bigger than the average summoned Lancer-class Cú Chulainn.

So yeah, I can spam the Cú Chulainn's [Noble Phantasms] like it could go out of style.

Also, I could say I would be able to defeat all those enemy servants in the Holy Grail War by myself if I don't get summoned into any servant class other than the Lancer-class. Not to mention I'm no longer bound to any oaths at all made by Cú Chulainn. Giving me a fresh start. Hell, I could even use my old name before Cú Chulainn if I wanted to.

Now, if I could only figure out why I was created. Yes, created.

Because I did not experience the whole rebirth kind of thing. I literally popped into existence in the middle of nowhere; well, I'm in a cave of some sort. But, that still doesn't mean I know where I am and how I got here.

With all the memories I got from Cú Chulainn. I would have to say, that I wasn't summoned for a Holy Grail War, thank the Gods. Because I rather not get killed the most tragic way like my alternative versions.

Plus, the fact that I don't see anyone nearby that could be my master or contractor, whatever they are called in this place. Whatever this place is, seeing how, unlike my counterpart. I don't get any implanted knowledge of this world.

So, I'm technically blind at the moment until I find a native to explain to me where I am and what kind of world it is.

Really hoping the native and I speak the same language, because if not, I'm screwed until I learn how to read, write, and speak the language of this world.

Talk about bad luck.

I let out a tired sigh, wondering if I should go by as Cú Chulainn still or not. Can't call myself Lancer; well, I can, but it is a bit confusing since I'm also a Caster and Berserker. I could go by my old name as well. But, I got the feeling it would feel a bit too weird being called by my old name when I'm, other me, used to being known as Cú Chulainn.

Then, I decided I may as well go with Lancer since I'll mainly use Gae Bolg as my main weapon to fight anyway. If I feel like it. I can just change it.

On another note, unlike all my counterpart. I don't have the drive to fight strong opponents right now. I've already experienced all the fights I could have for numerous of lives by now, which is technically true in a way.

Summoning Gae Bolg or creating, whichever it is, as the familiar red cursed spear appears in my right hand, with a habit from countless Cú Chulainn. I spin it around with one hand, then toss it in my other hand before return it back to my right and stop with Gae Bolg resting on my right shoulder.

Honestly, I shouldn't bring out Gae Bolg out in the open since it releases a heavy amount of bloodlust, ready to kill at my will, but who knows what things live in this cave. Better to have it out now than not and end up in a bad situation when I really need a weapon to fight with.

Knowing my luck, I should already expect I would end fighting with something in a matter of time before finding my way out of this cave.

Looking around. I see the walls are light green colored and wonder if I'm in an underground cave. If so, it's going to take me a while to get to the surface.

Walking around as I kept my guard up. Questions started to pop up in my head.

Like, why was I created with countless memories belong to Cú Chulainn?

How come I have the ability to switch battle armor from Lancer, Caster, to Berserker-class? While the clothes I have on right now is a simple white T-shirt and black pants, with a matching pair of black boots.

Another is a question is why I don't have any problem able to merge all the experiences together of Cú Chulainn, but not be too confused with the multiple memories of Cú Chulainn?

So many questions, but no answer to be given.

"AAAHHHHHHHHHHHHH!"

I blink when I heard someone screaming in fear. Ironically enough, I wasn't that surprising since wherever I am. There is bound to be enemies.

Being the hero I am, even when I really don't feel like putting my nose into other people's business, but my honor and pride, along with other things that made me; well, as Cú Chulainn.

With a quick burst of speed. I reach in time to see a white hair and red eyes boy was about to be attacked by a monster with a human body and a bull's head, a Minotaur.

I raise an eyebrow at this, but that all I did before throwing Gae Bolg straight at the monster, piercing the Minotaur's head to the wall, causing its blood to leak down from the head.

Not avoiding my range of detection. I saw a cute blonde haired girl standing near the dead Minotaur with a blank expression.

I can guess she was about to save the boy from being killed by the monster, but it looks like I got the kill before she did.

Honestly, I should say I did the boy a favor. Because his pride as a man would be hit due to the fact that he was saved by a girl. Not being sexist, but lots of males have pride, and knowing the boy, I can say I helped save his unless he one of those boys with weak self-esteem and the concept of pride would be a bit different compared to others.

Either way, I save the kid, may as well and my trace of thoughts was cut off when the Minotaur's corpse burst into a black mist and disappear a second later. Making it look like the monster wasn't there, to begin with.

I casually walk towards the two, causing both to tense up. With a bored look on my face, seeing how I killed the monster with ease and I could tell the boy wasn't much of a fight while the girl on the hand, could give me a warm up.

I grab Gae Bolg and pull it out of the wall, causing both the boy and girl to flinch once they felt the bloodlust coming from Gae Bolg.

"So." I look at the two. "Do you have any idea where we are? Because I'm lost."

I place Gae Bolg on my shoulder and stare at the two with a bored look, but I got a flinch still and started wondering if my eyes would cause others to be scared away.

"Uh, yo-you-" The boy tried to answer, but continue to stutter.

"Speak up boy." I said in a strict, but bored voice, causing the white-haired boy to flinch again.

"We're on the 5th floor of the dungeon!" The white-haired boy shouted in fear, causing the blonde-haired girl to tense up and look ready to strike or flee at any moment.

"A dungeon you say." I rub my chin with my free hand, "And where is this dungeon located?"

"It's located under the Babel! The name of the tower located within Orario that was built over the dungeon beneath it!" The white-haired boy quickly response in fear.

I nod my head a few times, "Yeah, I have no clue where that is. Do either of you two know a way out of here?"

"Yes, sir!" The white-haired boy shouted instantly, causing me to have a twitchy eye with how loud the boy is and can't fault him for it. Since I technically did scare the boy too badly, both by my Gae Bolg, which is still out and releasing bloodlust and should be put away for now. And doing so, the two let out a sigh of relief the moment Gae Bolg disappear.

"Alright. Come on. Lead the way." I said to the boy, then look at the girl. "You coming along as well or you have friends waiting for you?"

The blonde-haired girl shook head, that she not tagging along or don't have any friend waiting.

I raise an eyebrow at this, causing the poor lass to tense up again.

"I have friends waiting." The blonde-haired girl replied in a quiet voice, too afraid to speak out loud in my presence.

"Alright. Come on kid. Lead the way. I'm sure the girl is strong enough to protect herself while waiting for her friends to arrive." I said to the white-haired boy while telling him that the girl would be alright by herself.

After all, I can see that the girl is trained and could use that sword of her to kill. Unlike this white-haired boy has a minimum of training, but have the potential to become great if trained well.

The white-haired boy still scared and quickly speed walk towards the direction to exit this dungeon.

A few hours later*

(Orario: Dungeon: Entrance)

-Bell's POV-

'Crap! Crap! Crap!' These are the thoughts going through my head for the past few hours.

It was lucky for me to even remember the paths to exit the dungeon or risk angering the beast behind me, watching me like a prey if I so much as did something wrong.

By now, I swear I may have sweated more than in a lifetime, because my entire clothes are wet from the inside and sticking to my body uncomfortably.

All I wanted was to become a great adventurer, seeking fame and fortune, where in the end, I would have an encounter with a girl that has been attacked by monsters.

Sadly, this never happens and instead of rescuing a girl. I was rescued instead and by a beast in human skin. Well, at least I kept what left of my pride as a man than saved by the girl, a cute girl that is.

Right now, I have to do my best to lead this beast out of the dungeon and now that I thought about it. WHAT THE HELL AM I DOING?!

I'm literally leading a beast to a group of preys to be eaten!

I don't know about those other high-level adventurers, but I got the feeling they would be eaten by this beast like nothing!

'Kami-sama! Run away! There is a deadly beast behind me and close to be released onto the world! Run away and live! I won't make it!' I mentally cried to myself and already accepted my death and just hope a hero, a true hero, would rise to stop this beast from taking over the world.

"Hey, lad." The beast behind me spoke, causing me to sweat even more, but at least I didn't piss myself, yet.

"Yes, sir?!" I cried out in fear, not noticing the way the beast sighed in frustration as I was too afraid to turn around. If I didn't know the beast could outrun me easily, then I would have long by now run out the dungeon, leaving this beast behind and warn everyone about it before it comes out of the dungeon.

At this point, I feel like this beast spawned by the dungeon and something went wrong in the process, where the beast gains control over its life and desire to get away from the dungeon's influence.

"How long until we leave this dungeon?" The beast ask me, causing me almost to faint right there and then, but my willpower wouldn't let me and because I wanted to at least get everyone I know and love to escape from Orario.

"We're close to leaving, sir! We just need to go up these stairs!" I feel like I betrayed mankind for revealing this.

"I see." The beast mumble to itself.

'I'm sorry! I'm Sorry! I'm sorry!' I started apologizing to all the countless lives about to be lost due to my cowardness to not face this beast to the death. At least, I would be able to prevent it for some time before it escapes the dungeon.

Slowly, up ahead, I see the light and for once. I wish the light would disappear! Because in a matter of minutes, the beast will be free and it would be all my fault!

'Kami-sama, if I get the chance. I will come to you first and do my best to get us out of here!' I was at least determined to save the one person that believed me, to be a true hero. 'Some hero I turn out to be.' I thought with bitterness.

A few minutes later*

(Orario: Babel: First Underground Floor)

-Cú Chulainn's POV-

Upon climbing up the last stair, leading to a big circular room, with multiple columns at equal intervals and above is a beautiful azure painting of the sky that resembles the real sky. Along the circle are gentle stairs that spiral down into the dungeon, which I just came from.

"Huh, this is a nice place. Too bad it isn't my style." I mumble my thoughts and notice the way the kid tremble for some reasons upon hearing my words.

I just ignore it since I was too lazy to figure out why.

"Now, where the exit from here?" I ask the kid, who started to tremble even more than usual and slowly lead me to the exit, but why do I get the feeling the kid is heading to his death or something?

"Something wrong kid?" I ask with concern, but all I got was a quick shake of his head.

I raise an eyebrow at this, but decided not to push it. Not my business if the kid doesn't want my help.

Soon, both the kid and I head to another set of stairs up to another floor and I got the feeling this is when I get to see more people.

Haven't seen many people, yet on this floor, but I just toss it in the idea that not many are coming down here just yet.

"Let's see what kind of place is out this dungeon." I thought out loud, ignoring the kid shaking like crazy now the moment we enter the next floor.
