Ninja's Spirit ( Senran Kagura x Male!Spirit!Reader )

Prologue - Endless Darkness

( Third Person P.o.V )

Shadow Realm...

The world of shadows keeps many souls. Not all of them are evil but not good either. Those stranded inbetween also found their way here. This is the world where souls can rest and move to the other plains or ressurected as another livings beings... But not all of them. There are souls who are trapped in this realm forever without a chance escape. Souls of those who died and couldn't finish their ultimate goal or being bounded by strong emotions. Those cannot leave on their own...

There are, however, ways for them to return to the land of the living in material forms. One of those forms is being summoned by a powerful person who will bring out an ancient ritual. The goal of the ritual may range in what the summoned ghost is to do. From a simple servant, to spy or even a deadly assasin with expirience from previous lives. One soul may have many uses and awaits for final moment to return and finish their ultimate goal. But there is yet another way...

If a person hides a large amount of hatred in their hearts or seek vengance their very own spiritual aura may shoot out like a flare for unresting spirits who will rush to such an open well and jump to the world of living. Outcome depends on the current state of the person who's feeling summoned them. If this is an anger or other negative emotions the spirit will appear as Oni - demon. If the good feeling is great enought it may also summon a ghost of element or part of nature. A powerful part is vengance...

When person seeks vengance with all their heart and will beg for justice the spirit will appear as an merciless assasin born from shadows with only one goal. Kill. This spirit will listen to it's master for the time being and roam the world of living reaping the sorrow of it's master heart and kill responsible for what caused the need for vengance. Those spirits have name - Aragami, The Vengeful Spirit. They will most likely disappear after they're done with serving the justice but death of their master, not being able to deal justice or more strong emotions may bound them to this world in mortal shells once again...

Once the dark emotions take control over person's heart and they seek a way to fullfil their desire a certain spirit may appear. Oni, The Demon. They are feeding off of theirs summoner spirit and living energy to stay in this world. They will stay by theirs summoner's side to continously flare up their negative feelings so that they can have even greater feast. Oni become extremely powerful the more they feed and they will protect theirs summoners so that they can feed more. They can stay in the world of living after feeding enought, they possess the summoner if they give up or if the summoner will accept the demon...

If those are the great good emotions flooding person's heart and mind a diffrent spirit is summoned. A free spirit or so called Yokai. They may be called many diffrent names, like : kitsune, kappa or tengu - depending on the emotions which summoned them... They roam the earth freely once released but can stay near their summoner as to be sure to not break the link connecting this world to shadow realm. They are good spirits who love many diffrent things dependable on their summoner. They can stay in this world if they can find themselves their elemental spot, become protectors of shrine or fall in love with their summoners...

All of those forever bounded souls keep on scratching at their locked prison in hopes of someone summonging them or someone letting out enought emotions. Those souls are cursed and forgotten even by the gods. Among those forgotten souls may even be the greatest of heroes or the worst of the villains. No one is sure about what may hide the locked Shadow Realm. However, most of the scrolls with hidden knowledge had been already destroyed and there is no known ritual in the modern world but emotions still flare up...

Among those souls is one that may be tainted with darkness or covered in light. No one knows that one soul but it keeps on roaming the Shadow Realm searching for a way out. The soul that was here many times and every time they left. In the past life, however, the soul must have not finished their ultimate goal and now was bounded to suffer until it will find a way out. As the soul kept on moving throught dark scapes with view of many others passing a gate to ressurection the soul felt something. A pillar of glowing lights appeared nearby and soul moved as fast as it could to answer the emotions and leave the shadows...

No one thinks at what may be those emotions... The soul rushes to the exit and enter the stream of emotions being pulled into the world of living with relief and excitment entering it's pained existence... Time to live...
