The Dark Side of Great Ocean

[ Many Years Ago. ]

" Gramps, who are those who come into our dojo... " Galen says to his father as he sees a person with Blue Hair with some other that uses robes, come into the Stinger family's dojo at that time.

As Galen helps his grandfather and points out those robed people he sees in front of their family dojo, Galen's grandfather was shocked to see them.

" Galen..., my boy. " Galen's grandfather says as he throws his cane.

" Grandfather, what are you doing, your cane? " Galen says as he picks the cane.

" They're still on the front, I and the other disciples will meet them," he says in sweat.

" While I'm gone, go to the [Hive Chamber] that contains all of our ancient books and bring the most important books you can find with you. " Galen's grandfather says as he then summons his disciple behind him three of them take Galen away immediately.

" Grandfather, wait! " Galen says as he was taken away at that moment he sees a flash of light coming in front of his grandfather's direction.

...

"( He wasn't bluffing around... )" Galen says right after hearing the Dark Brotherhood Sect's name.

As Galen hears it, he then realizes that Ragna was telling the truth the entire time, since the reason he enter this Raid despite the odds is to kill Adrian Waterson who the people had suspiciously noticed that he is part of the Dark Brotherhood Sect.

"( Adrian Waterson, the leader of the Great Ocean Guild... )"

"( After becoming a Hunter for some time, I also begin to notice his suspicious activities from one of his men that I had been going to Raid with. )"

"( At that time, one of his men starts a riot during the Raid and killed many Hunters at the time. )"

"( I was the only survivor. )" Galen says as he remembers back then fighting the Great Ocean Guild member, when he fight him, the Great Ocean Guild's member named Aaron released a weak Demonic Aura similar to the Demonic Aura of those Black Robed people who fights his grandfather and destroys his family dojo.

As he sees the similarity, he then uses all of his [Stinger Martial Arts] techniques to defeat Aaron quickly while asking how Aaron has such a demonic aura inside him. At the time, Galen was so in rage as he uses many of his martial arts techniques to defeat Aaron and immediately managed to defeat him, but during that very time.

" Ahahahaha... Martial Arts, hey? " Aaron says as he unleashes his [Sin Mark] which also reveals that it begin to already form a [Sin Core].

" What the...? " Galen asks as Aaron suddenly teleports in front of him.

" How very old..., I thought people had already abandoned the use of Martial Arts around the world? " he says which made Galen flee to maintain a distance but he was immediately followed by Aaron who immediately received great speed.

" But it seems there are some that maintain that old and boring way of fighting! " Aaron says as he uses his which increases his speed tenfold, making Galen almost disoriented for some time. But after some long fight, Galen decides to get serious and use many and many of the [Stinger Martial Arts] most dangerous techniques.

So dangerous that as result...

" Kuh.. Kah... " Aaron's body was destroyed as some of his internals exploded for Galen must have used one of his dangerous acupuncture techniques and imbued it with his power, thus resulting in the destruction of some organs.

" You... " Aaron says before Galen pressed his body on the ground with his feet as he asks him about some information he wants to know.

" Now tell me... "

" Where did you get that kind of power? " Galen asks Aaron and Aaron just bluntly says the details that he gets from the Vulture Guild (Ripper Jack's Guild).

" And where the Vulture Guild get it from? " Galen asks but it seems Aaron is no longer available at the time which he then left him to rot inside the Dungeon.

"( The Vulture Guild, huh? )" Galen says while bringing some things that he picks from Aaron's clothes, including his phone that contains many things related to the Vulture Guild, showing many clues that he must have brought it from them.

...

After some time, Galen then attacks some Vulture Guild base that he deems to have important information regarding those with Sin Marks that had successfully created a [Sin Core].

" I... I didn't really know... " said one of the Vulture Guild Captains that Galen pinned after dealing with the other members.

" You lie, Aaron from the Greater Ocean Guild says that you're the ones that gave that knowledge to him. " Galen responds.

" And... and you believed... him..., that Great Ocean... bastard...? "

" He... didn't get that information or anything... from us... "

" We're... the ones... who stole it... from them... "

" From them? " Galen asks.

" From... them..., from the Greater Ocean Guild themselves... " the Vulture Captain was pacified after Galen locked him and after it, the information he needed was spoken, Galen then feels stupid after attacking the Vulture Guild and decided to turn around and observe the Greater Ocean guild led by Adrian Waterson.

For many times, Galen observed the Guild's activities by often joining the Raid filled with the Great Ocean guild members as he spied on them to see many of their activities that were also found to be suspicious, not even during the Raid, but the Dungeon they choose is a place filled with Demonic based treasures and artifacts that should've been purified first by the priests before the Hunter could take it home completely.

"( The Great Ocean guild is so suspicious, after many times following them, I can immediately hypothesize that they must be doing something illegal or... )" Galen suddenly stops thinking right after he hears a Great Ocean guild member's conversation in the G District Hunter Association Building's Basement.

" It seems we'll be having more Sin Core users in our members, didn't we? "

" Guess so, after all the Guildmaster himself is the one who secretly promoted it... "

" Really? "

" Of course, don't you heard that the Guildmaster is rumored to be aligned with the 'Dark... "

" *Shush*!!! " the other person says while Galen still hides to spy on them.

" Don't say it out loud you fool. "

" If you say it loud, the [Sharks] might be hunting you as they smell your scent of betrayal, "

" Especially if you said the [Dark Brotherhood Sect] word in public, without any... "

" Oh, shit... "

" We have to leave... " the Hunters say which made Galen curious about why they are running away.

As he tries to follow them, he then felt someone behind him with a Demonic Aura.
