Chapter 1- "the midst of war"

Sasuke approaches Byakuya who is standing in the middle of a shallow pond in a grassy field.

Sasuke: So you are the head of the Kuchiki clan? Kuchiki Byakuya?

Byakuya: ...

Sasuke: you must die for my Ideals to come true. Once i defeat you, i will become one step closer to being strong enough to fight.. him.

Byakuya attacks with a downward slash to Sasuke's head, Sasuke tilts his head to the right side and blocks with the katana on his back, and flows lightning chakra into the katana with his right hand. byakuya's sword shatters. Sasuke does a horizontal slash and byakuya backs off.

Sasuke: you will fight me with your full strength, otherwise, i will crush you.

Byakuya: a mere human such as yourself does not stand a chance against the head of the Kuchiki family. leave now before you speak disrespectfully to me again.

Sasuke: you are clouded by your honour, as you do not even recognize one of the Uchiha clan. the strongest clan.

Byakuya: hmpf, so be it.

Sasuke throws lightning charged kunai at byakuya, who dodges and shunpos behind Sasuke and attacks with a backslash which Sasuke parries with the lightning katana and byakuya's sword shatters again. byakuya shunpo's away and Sasuke uses grand fireball technique which Byakuya blocks with Bakudo #39, enkosen (arc shield) and shunpo's away again.

Byakuya thinking: so it seems that katana is electrically charged to increase its cutting power and destructiveness.. it also most likely paralyzes with each stab or any physical contact... also, that fireball attack he used seems of mediocre power as enkosen was able to completely reflect it.. he is quite powerful.. but how troublesome.

Sasuke attacks again, this time activating his sharingan and using taijutsu after he sticks his katana in the ground. he uses a handstand upward kick to break byakuya's guard and kicks byakuya in the chest with the other foot. byakuya goes for a spinning backhand fist and a uppercut with the otherhand but Sasuke dodges them all. byakuya backs off again.

byakuya thinking: hes faster! and he's predicting my movements perfectly! that damn sharingan..

Sasuke: fight me seriously! i must test my strength.. i cannot waste my brother's sacrifice! i will become strong enough to defeat whoever badmouths him! i was told that you were strong. and that you trained with one of the senju clan in the past!

Byakuya: fight you seriously? a brat like you would not be able to stand against me. no matter what you say,
i won't take you on with my full power.

Scatter, Senbonzakura.

Sasuke sees the hundreds of thousands cherry petals flying towards him and smirks. Sasuke uses the grand fireball technique again and runs into it. which is then surrounded by cherry petals.

Byakuya: this fight is over.

End of Chapter One.
