Konoha's Blondie: The System Insists Sasuke Is Kushina

(Dual female leads: Sasuke + Sakura. Team 7 should keep it in the family.)

After being born into Naruto Uzumaki's body, on the eve of the Chunin Exams, I awakened memories of my past life and the [Blond-Haired Roleplaying System]. Acting like a blond gets me stronger!

But the System insists I'm Minato and wants me to reclaim the surname Namikaze.

During the Chunin Exams, the System assigns a mission: [The Third Shinobi World War has broken out. Cover the retreat of Yamanaka Inoichi, Nara Shikaku, and Akimichi Choza!]

I grabbed Ino and Choji and ran for our lives, shouting, "Inoichi-san! Shikaku-san! Choza-san! Run!"

Ino: "??? Am I my dad?"

After the exams, the System issued another urgent mission: [Your destined match, Kushina Uzumaki, has been kidnapped by the Hidden Cloud Village. Go stop them immediately!]

I rushed to the Valley of the End and saw the person the System identified as "Kushina."

That was Sasuke Uchiha, who had just defected! And she was a girl?!

I used the Flying Thunder God Technique to teleport straight in, grabbed her in a princess carry, and forcibly brought her back.

After we returned to Konoha, the System nagged me every day: Please marry Kushina as soon as possible and give birth to the Child of Prophecy.

I gazed at Sasuke, now back in women's clothes, and fell into deep thought.

When the entropy of space (Namikaze Menma), the entropy of civilization (Indra), and the entropy of time (the transmigrator) collide, two souls that should never have existed decide to join forces to trick the System, the Otsutsuki, and everything in this world.
