 Ten's Citadel... many lifes taken, many blood from both sides...

The great toji face many battles and is wounded over and over.... eventually returning to the dreadwoods, and without tell without want a piece of him is dropped on ground.

That piece crawls away seeking protection, cover, so weak and pitful, almost invisible to sight, that even toji dont noticed it fell from him, his mind always focus on the next battle, a shard from toji.


Eventually crawling and dranning the essence of that place it develops more and more to the point a egg is born, flesh and warm, filled with occult magic, toji great healling skills provided such recovery into this egg but it took all energy toji shard had to heal , a new being is made, from his flesh and from the dreadwoods essence.

Weeks pass and the egg bloom into a new creature, a spawn from it... it was not planned or desired by the demon, as it not needed reproduce itself.

Unplanned, not borned properly, and full of flawns the new demonic creature breaks free from his flesh prision
a body fully defective, that had drained all the small bits of that toji shard was, in oder to grow. 

Pathethic, weak, killable, however it did inerted something from creator.
A great hunger for battle and martial arts.
