Wallie it is. U_U
When the SO6P fought the Jyuubi, the battle waged on years and years and the foul chakra the Jyuubi exorted was so great that it scarred the earth, so dangerous that it was almost living, hoping to find someone to live off of in exchange for power. It latched itself onto Anshoku, burning the clan's symbol of Demon on his palm, the same very symbol you have on the inside of yours. Trying to get back closer to it's orginial master, it traversed back to the moon, where the Jyuubi was sealed. However that symbol on Anshoku's hand allowed him to summon this chakra through the use of portals.
As for the abilities, I'll going to post a section of them and explain each to ensure you got it.
"The abilities of the Nekura center on the summoning and control of this foul chakra of the Juubi's, that the clan calls "Keigoku". The chakra is warped from the moon by a clansman opening the dimesional portal, through which the chakra enters the battlefield. This is much like a Summoning jutsu, which brings objects from a different place through dimensions. The portals can be opened anywhere on the battlefield. However, note that they cannot be used for transporting the user, opponent etc. over dimensions. Only Keigoku can transport itself through the portals. The portals are silent and do not actually count as a jutsu, however the release of a Keigoku technique from them is a jutsu; furthermore, it's not as if the portals possess any use outside of transporting Keigoku anyway.
Essentially the main ability of the clan, we access this chakra we called Keigoku through the use of portals we open up. Think of it as a s/t hallway of sorts, one door is open on the moon, where the chakra of the Jyuubi travels through and another portal is open somewhere on the battlefield, in short wherever you choice to open it. We can only send Keigoku through these portals, nothing else. Opening a portal doesn't count as a move but seeing as to merely opening a portal does nothing and doesn't prevent a jutsu from hitting you, you can see it as completely useless unless you channel chakra through it in the form of a jutsu.
The power of the Keigoku, however, is not to directly affect physical objects. The Keigoku is so corrupted, that it causes searing pain to an opponent's mind if they have been touched with the energy. Much like how prolonged exposure to a fire can cause extreme burns, prolonged exposure to high-rank Keigoku techniques can cause a complete shattering of the mind and possibly a vegetative state. This also lets the Keigoku pass through physical substances without minds, such as earth, water or trees to reach a target behind it, since it loses none of its powers on the non-sentient object. Should the Keigoku touch a Summoning, it will turn them against its master
The Keigoku doesn't do any physical harm to a foe. Well, that's to say it doesn't affect the opponent's physical being. The Keigoku is a chakra so foul, so corrupt, that it rots away a foe's conscious and mind. Once contact has been made with a foe, even the slightest of brush against exposed skin, causes great agony upon their brains and mind, taken the concept of mental torture further than genjutsu can take it. Prolonged exposure can cause great damage to their brain, leaving the foe in a comatose like state until they receive training. Because it focuses on the actual conscious and soul of an object, it is able to pass through solid material, such as trees, buildings, waves, etc. However that all depends on the rank and experience of the user. A seer's Keigoku is unable to even pass through a door while the Clan Head on the opposite end of the spectrum can send his keigoku through something as large as a mountain range, depending on the rank of the jutsu used. If the Keigoku touches the mind of a summoning, it causes the mind to go through great pain, not enough to disburse, but enough to corrupt the mind, turning it against it's master, making it a temporary ally as long as it's on the field, depending on the rank of the technique.
Skilled users of Keigoku have been rumored to shift its focus from merely shattering minds to bending them or manipulating them with even direct eye contact initiating a transfer of Keigoku between people. However, this can only be done by extremely high-level Nekura and requires special training from the Clan Head. Similarly, skilled Nekura above a certain rank possess one of the most useful powers. The Drain. Once one of their Keigoku attacks have connected with the opponent, istead of letting their Keigoku dissipate, the Nekura bring the Keigoku back to them and pour the stolen strength from the opponent's mind into theirs. This firms up their mind, and even if they have injuries makes their mind pretend it isn't there and force the body to function as it normall would. Since this isn't really a cure, after the battle the Nekura will feel their injuries again plus an extra 25 damage points due to the strain of forcing their body. As many damage points as the opponent is hit with, that many damage points the user may force their mind to believe it isn't affecting their body.
Two of the strongest techniques of the clan, the Evil Eye transfers Keigoku directly to the face of the foe, causing intense pain near instantly. The Drain does exactly what the name says, drains the target of chakra and brings it back to themselves, powering them more and allows you to fight longer despite injuries you might have sustained. Of course, these jutsus are advanced and only the Cla Council and up can learn the Evil Eye and Possibly Black Knight and higher for The Drain, I'm not sure atm.
Another side-effect of wielding the Keigoku is that any Bijuu, whether incompletely or fully transformed, believe the Nekura to be one of "them" since the Nekura wield the same chakra that the Bijuu were made of - just not in the same amounts. The Bijuu therefore refuse to attack the Nekura. Each Nekura is given a cloak strong enough to keep out normal weapons strikes. An unwanted ability is that of the Nekura's bodies, after or during a battle, being so filled with Keigoku that they reject any foreign chakra from entering their body, and stop it instantly. This means that medical ninjutsu have to force harder to overcome the natural resistance, making Nekura extremely hard to heal, roughly three times that of a normal patient.
Due to the Jyuubi's chakra, the Keigoku, always surging through off, it makes it impossible to inject any form of foreign chakra inside of us, including Sage Mode, Curse Marks, Genjutsu, Jyuken, Kiyoshi and other techniques/abilities that might inject chakra in you (however attacks that use chakra as brute strength still work). It is due to this same chakra that Bijuu are unwilling to attack us, even in their incomplete forms. They associate our chakra with that of the Jyuubi, believeing us to be one of them. The Jinchuriki can attack us but his Bijuu will be unwilling. However, we can be healed after battles, once our body is worned down and defenses are lowered. They'll have to work 3 times as hard, likely using higher ranked jutsus to heal small wounds. Luckily, we have a very special cloak, that blocks most weapon strikes, including kunais and shuriken.
Read it, learn it, study it. Any questions?
