After I Swapped Bodies with My Mortal Enemy

Senju Tobirama and Uchiha Izuna are sworn enemies.

During one battle, Senju Tobirama used his self-invented Flying Thunder God Technique to run Uchiha Izuna through.

That night, Senju Tobirama enjoyed a good night's sleep for the first time in ages.

Who could have imagined that when he woke up, he would have become Uchiha Izuna!

*

Uchiha Izuna was reborn. In his previous life, he had died with regrets after Senju Tobirama ran him through with a sword. This time, he decided to seize every advantage and kill Senju Tobirama!

But when he opened his eyes, he discovered that he had become Senju Tobirama!

This is just too ridiculous!!!
