Reincarnated as Izuna: In My Previous Life, I Was the Great Demon of Annihilation

Having an older brother was something I wished for in my previous life.

And now I really do have an older brother, an unbelievably amazing one at that!

It's just a shame that the world is at war, and our mortal enemy lives right next door.

Oh well... Life is bound to have its disappointments.

But... why does that watermelon-haired guy next door keep bothering my brother?!

Nii-san! Don't let that damn watermelon head fool you!!!

And you, white-haired creep!

What do you mean by kissing me on the cheek?!

Are you trying to disgust me to death?

I refuse to die that way!!!

By the way, my name in this life is Uchiha Izuna. In my previous life, I was an Annihilator Lord.

(Tobirama/Izuna pairing, Hashirama/Madara friendship)
