The only reason I asked to do a job or go a round-a-bout way is to get on their good side. Sure I can just make them teach me with my Ginga Rinne Sharingan but I would like to come back so acting in a disrespectful way or antagonizing them is not the way to go. I have no depth perception when it comes to magic so I don't know if they can break my hypnosis anyway. Even if I can end them all, I will not be able to learn anything. By taking a job, even the 100 year one, I can take one or a few of the guild members with me so I can learn or if they let me, read their minds. Will someone who is taken against their will sincerely teach someone? Hell no! If anything they might teach me to implode or make me weaker. By being forthwith and semi-honest I can at least reassure them that I am no enemy and that they can teach me without consequence to them.
After waiting for the guild members to pick themselves up, we headed back to the guild hall. Once everyone calmed down, Mirajane handed a little pile of job requests. All of them were 10 and 100 year jobs. Since I couldn't read the words of this universe, Mirajane read them to me. I picked a 100 year job to subjugate a dark guild that has been operating for some time now. As proof of the subjugation I needed to have something that belonged to the dark guild mages.
Sage: So I just need to take out this dark guild and show proof that I did?
Mirajane: Yes. But according to this, you will have a hard time with them. There are about 15 dark mages and have a moving guild hall. All 15 of the dark mages have S-class power.
Makarov: Maybe you should hold off on the mission.
Sage: Nah, I just need someone to come with me. How about Mirajane? I promise with me there, no harm will come to her.
Makarov: That is up to her to decide.
Mirajane: Just promise that if the danger is too high we will abandon the mission.
Sage: Even though I doubt I will leave the quest unfinished, sure, if it will put your mind at ease.
Once Mirajane was done preparing and I was done restocking on food, we left the guild. Along the way Mirajane gave me the alphabet that they use but that is only for their modern words. My real reason for taking on a 100 year job it to read the minds of those with an extensive history like the mission we are heading to now. No one will miss them so I could read their minds then kill them. The longer these dark mages have been alive the more knowledge they have accumulated. Mirajane told me that by the time we reach the destination of the contact would be a month from now so I told her to hold on to me and tell me the direction. I grabbed Mirajane into my arms and flew at high speed.
After a few minutes we reached the destination. It was a small station with a minimal amount of people. The people we met up with were tracking this particular dark guild for years. They put in requests for backup to finally be rid of them but, like the name suggests, it's taking 100 or more years and it's still not done. An elderly man came to greet us.
Old Man: Hello. My name is Marlin. You must be from Fairy Tail. To be honest we were reluctant to accept you taking this quest considering your guilds track record.
Sage: My name is Sarunokami Sage.
Mirajane: My name is Mirajane Strauss. We understand your concerns and we will do the best we can to complete this quest.
Random subordinate: Ha! "Complete this quest?" Don't kid yourselves. We can track these dark mages but we can't bring them down, that's how strong they are. Our group is made up of all the villages they decimated. We are the second generation to inherit the avenger mantle. In a way you can say we are taking revenge but no one has been powerful enough to bring them down. Sure, we were able to kill one or two but they know necromancy as well, so their numbers stayed the same.
Marlin: Baste, that's enough. What he said is true. Unless we can get rid of them all then your help won't matter.
Sage: In total, how many are there?
Baste: There are 15 dark mages in total with the ones they resurrected. Although the number mages they have is small they are all powerful. If you really have the power to kill them then it will take us a few months to kill a few then track where their guild will move to next.
Mirajane: What do you mean?
Marlin: You don't really think they will idly stand by as you eliminate their members without them having a plan, do ya? When ever we have them on the edge they activate some ancient magic in their guild hall and are teleported somewhere else and we have to track them down all over again.
Baste: They haven't moved for the past 10 years so they must be really confortable with this particular spot. According to the intel we have gathered they took in other smaller dark guilds. Their main force are the 15 but since they have taken in new members that number should have risen.
Sage: Just tell me where they are, that's all I wanna know.
Marlin: Hmph! Youngin's just looking for a place to die. Baste, we won't have any luck with these helpers. Just tell them so they can die and we can expect better reinforcements.
Baste: Fine.
After receiving the directions I told Mirajane that I will go on my own. I found the guild hall of the dark mages and snuck in. I found a few dark mages guarding the entrance they must be some of the new guys they brought in but I knocked them out. After reading their minds I found out that they have implemented a mental barrier just in case their minds were read so the important information of their activities was blocked. I cared less because I was after their magic not information about them.
After finding a few more of their members, though none of the 15, I took all their magic knowledge. Some even had the same power as Moro so I was ecstatic to know how to counter it. One way was to make him absorb more than he can handle but that wasn't an option since he is a 10 million year old glutton. The other ways were know how to stop his magic from draining you, since I learned that magic just now but at a much weaker state, it was still good to learn. I took more of their members and learned as much magic as I could. I killed all the members' whose minds I have already read. When I encountered those with copied magic, I killed immediately. I stored their heads and bodies in a dimensional pocket and moved on. Once I got bored I saw members of the 15. I stepped out of the shadows and got their attention.
Sage: I'm tired of killing your minions.
Dark Mage1: Who?!
I practiced some of the magic I learned and erected a dimensional barrier, trapping the entire guild hall and stopping them from teleporting out. Once the barrier was up I sensed around for all those in the guild hall. Once I got the locations of the remaining main 15 dark mages I let my crazy out. In order to practice the magic I learned I killed them with it. I drained one so much that he turned to dust. There was one move, Revenge slash, that I learned from a grunt that when cut, even if it heals, the pain from the wound persists and bleeds occasionally. The stronger the user the more damage is done, duh.
Sage: Come at me you little twats, daddy here wants some blood.
I grew tired of waiting so I used Shadow clones to start taking heads. When all the main 15 of the dark mages remained they grouped up to where I was.
Sage: So this is the remains huh?
Dark Mage2: This isn't the remains, we are the main mages. What you got rid of was the extras.
I smiled as I flicked my finger and killed one of the 15 on the spot. All they saw was their comrade's head fly through the air before it disappeared into my dimensional pocket.
Sage: Main, extras… it doesn't mean a thing to me, you will all die just the same.
Before killing them I read their minds and broke their mental barriers. Once I learned their magic their heads will be lopped off. After decimating all of them and grabbing their heads as proof, I took down the barrier and walked out of the dark guild. Once I saw Mirajane waiting for me she became worried as she gave me a check over if I was ok.
Sage: Don't worry, this blood isn't mine.
I turned around and used Tengoku no Hashira (Heaven's Pillar) on what was the dark guild. In a blinding flash the dark guild was no more. Once I confirmed all the heads of the dark mages, even the new ones they brought in, with the Old man and his group, we confirmed the completion of the 100 year job.
