Seijuro is born, yet he is all alone, his parents left him and the only thing he remembers is the haori that they gave him, Which still faintly smell like them.
The God's and Demons are fighting a battle to the death, which the God's are losing
The Universe is divided into 3 dimensions, the God's reside in Heaven while the Demos reside in hell but in between them they are 7 layers which and infinite amount of planet's reside in them.
the quick witted god's Took all the people that resided in the planet's and forced them to fight the war. Seijuro's parent's went to the war in which we are yet to see if the will come back alive or not come at all.
The God's gave every race in the 7 Layers a power called Blessing which gives you a power that some even rival the gods Magic, Swordfight, Martial arts everything you could name you could get with the power of the blessing, Every person has a individual blessing only able to themselves which represents they're soul and beliefs,Some were born with it some had to achieve it, the battle between the God's and Demons was reaching it's climax with the God's winning thanks to the all the races from the 7 layer's. In the end the some demon's managed to escape but most of the race had been killed in battle,But the greedy races tried to fight for they're power they got destroyed and were made to be executed by their family members,Such cruelty from the gods made no race in the 7 layer's disobey the God's, But there was a miracle seijuro's parent's Blessing wasn't removed intact it got upgraded his Blessing special ability was to give blessings to people with the power of Seijuro's parent's Blessing they were able to give they're own type of blessing to every race in the 7 layer's but that came at a cost, they're death.Seijuro was left alone with no one but the heavens, earth and water to keep him company he was truly alone, at the age of 10 his Blessing awakened which was strange to awaken a Blessing at this age, most people awaked it when they were Under 5 year's old, the late bloomer Seijuro spent his day's training with his sword his sword name was Hontōni soko ni he swung it like it had a life of it self when Seijuro awakened his sword transformed.... into what?
