The True Fight: Seireitou Hyuga vs Hikaru "Shadow" Kurosaki

The Story Thus Far
3 years ago, a fight that nearly destroyed the world occured. This was a battle between the Denkiteki Sannin no Ninseken. Since then, they have trained to hone their skills, becoming stronger than even Rokudou Sennin, Zukia Tojiro, and even Myoken through their combined strength. They have since retired to their respective positions: Ryun Uchiha as the Gokage Sennin, Seireitou Hyuga as Lord Sekennousama, and Hikaru "Shadow" Kurosaki as Rosutorikujou Sennin. They have fought together, trained together, and survived the tests throughout their training. After all this, Seireitou Hyuga has traveled to finally earn the respect of his rival, and friend, Hikaru "Shadow" Kurosaki.

Sake, With a Side of Battle
Hikaru was walking through the streets of Kurisutarugakure admiring the architecture. He was in the village to meet with Lady Kurisutarukage, to discuss the progress in the Crystal Mines. He then sensed a familiar prescence and noticed a note on the ground. He picked it up and read what it said:

Hikaru,

''I feel that our last fight was a little unfair, considering you lost all motivation after I used my Shukai. I wish to fight you again, but I want this one thing.''

Hikaru looked further into the letter, and read the bold print.

Release your Shukai, or I will kill you.

Hikaru swore, then said to himself, "Doesn't he realize the consequences?" He then looked further in the letter and was stunned to read:

''But I want to fight you in my realm. I realize the danger it brings to the Human world, and the Other World can withstand such power.''

Seireitou

Hikaru sighed, and then he wrote on the back of the letter:

I Accept.

He then saw the letter disappear, and another letter was in it's place that said:

''Good. Meet me at the site we fought at 3 years ago.''

With that, Hikaru set out for the field near Kagegakure 2.
