Inuyasha's father and mother are enjoying each others company when a strange miasma of a powerful demon Rashinki starts spreading and it starts to take over the mind of his wife because she is human so with out Inuyasha and Sesshomaru father realizing that she was being controlled he let her leave and she went to Sesshomaru, where since Rashinki could use his powers through people he takes control of Sesshomaru. Using one by the name of Onigumo, Rashinki controls Sesshomaru mind and he leaves in the middle of the night, already sad from his human wife leaving he goes to check on Sesshomaru and finds he is gone getting angry he sets out to find his wife and child as he sets out he comes across many humans who have weird symbols on there fore heads and where heading toward the castle and some of the humans even seemed to have there scents changing and there where many weak demons or where suppose to be weak kept attacking Inuyasha's father but even the enhanced but still weak piles of demons where no where in his strength rate so he blew them all away but as he fought the scent of his family seemed to be getting further. He did not want to harm the humans so he would just jump over them after transforming into his demon form he would jump from open place to open place yet still the scent of his family kept getting farther and farther still he decided to act like he was controlled and follow everybody else still he got to the huge mountain castle. After getting to the place where everyone else went he saw a huge mountain in the shape of a castle with no entrance with people just disappearing and when he tried to go trough the wall he just hit it and the scent which was very close seemed to be growing farther and closer at the same time which he couldn't understand and it was like it was coming from around the whole world and then he realized it was the miasma that had control over the human but he couldn't see where it was coming from. The miasma that controlled the weaker people and demons was there but not visible, the wearier people and demons would just have to smell the miasma and would fall under Rashinki's control while others like him had to be under direct control of the mountain ruler. The castle was huge with towers left and right truly the biggest castle he had ever seen but there where no doors so how did people and demons get throw he sat down and thought, then realized that people where not going throw the wall it was just a barrier that looked like a wall so he broke down the barrier and saw these huge golden doors and saw people going threw them so he followed, transforming back into his human form he leaves the line of people and starts running around the huge castle it was not only huge above ground but he had an underground castle connected to the above ground one the, great dog demon ran around till he found what looked like that main thrown room but who does he find waiting for him non other then Sesshomaru. He sees his son Sesshomaru standing with the symbol on his head and all of the sudden Sesshomaru eyes turned totally blood red, redder then ever before and his nails started growing which showed he was becoming even stronger then his body could handle, which if any more power entered Sesshomaru's body he could die but right before the breaking limit the energy flow stopped and Sesshomaru started attacking him with his now razor claws moving faster then his father. Sesshomaru's father bewilder by how strong Sesshomaru had suddenly got was slashed hard along his back that kicked in the wound, Sesshomaru's father pleaded Sesshomaru to stop and doesn't fight back getting several more injuries. Sesshomaru is about to kill his father with his claws inches away from slashing his fathers throat out he stops and the symbol started to crack and it suddenly shattered all the dark energy dispersing from him and the jewel that holds his memories cracks Sesshomaru falls to the side and mutters father I will defeat you on my own and not with someone's help. Sesshomaru's dad smiles and gets up and walked throw the doors and to his disgust he sees his wife next to Rashinki in different cloths Rashinki says "heh heh I see your angry that your wife is now mine" Sesshomaru's father breaks out in anger at the thought of this demon having his wife, he spit at the thought of it and he charged at the demon only to revel that the demon nor his wife where there only a miasma filled puppet pelt, the scent was still strong though signifying that they where in the room somewhere with his thought of finding him he starts to tear the innards of the castle apart. He starts getting really pissed till suddenly a strange scent leads him to a room, he goes in and once again and sees his wife with Rashinki but this time they where real he started cursing up a blue strafe at Rashinki and it started. It was Sesshomaru's dad that attacked first, it looked like a dog fight, both had become there demon forms lunging, biting, clawing, scratching, and hitting.
He was still weak from his fight with Sesshomaru so he couldn't move fast enough to dodge all of the attacks and didn't know what to do but kept fighting. After many painful hit, Rashinki seemed to have the advantage even after Rashinki knocked him out of the castle but once he was at the door he started building his energy into a humongous ball of energy but right before he could launch the attack Sesshomaru's father used his energy to put a locked seal on the door encasing him and freezing the castle with everything in it but not before all the people where freed and his wife was spit from the castle and to seal it shut he used one of his fangs and a claw on the huge handles making a barrier round it to hid the castle mountain to look like a regular mountain. Rashinki was put under a spell so the fang would bind the door and that claw would hold a spell over him that would put him into a sacred sleep for what he hoped was forever some would quest for the castle because there rumor of there being a huge room filled with gold jewels all sorts of things, he had his son and his wife back and went back to protecting the land yet forever more Sesshomaru despised his father even more then he ever did for him saving his life and for years he had a terrible fear yet a flaming hatred to Rashinki and after that all the freed people went back to there lands and hope that he would be sealed awat forever
