Evil Uchiha brat, I'll marry you myself.

Main characters: Koki, Uchiha Shizumizu
Synopsis: [Single female lead][Very sweet in the beginning][The female lead turns evil and becomes violent later on]
Transmigrated into the body of the Second Hokage, living in the same era as Hiruzen Sarutobi, Koki Senju, who did not display any talent, did not receive Tobirama's attention.
He had no intention of standing out; he only sought to protect himself.
Until this day, Koki learned that his fiancée had also traveled through time and become the evil Uchiha brat in the eyes of the Second Hokage.
From then on, Koki joined the Ninja Academy and became a ninja student along with Hiruzen Sarutobi.
He punched Hiruzen and kicked Danzo, gradually revealing his strength and talent, which began to shock everyone, and even showed signs of becoming the next Hokage.
When Tobirama learned that his favored son was going to marry an Uchiha, he called him a rebellious son and fainted from anger.
……
Until one day, by chance, Uchiha Shizumi witnessed Koki's chest being pierced.
Overwhelmed with rage, tears of blood flowed, and the two tomoe opened in a furious burst into the kaleidoscope.
"I will end this evil and cruel world. Ancient Tree, I will create a world with you!!"
......
"Heh heh, a body resurrected through Edo Tensei, then this era belongs to me!!"
