The Strongest Marshal in History

After transmigrating into the world of Digimon Tamers, I became Ruki Makino's older sister. But how can I make my mark in this world?

Ruki Makino: "Sis, what exactly are you doing?"

Lengxiang Makino: "Be a good girl and keep it a secret. Don't tell anyone."

"Or just you wait. I'll make you wish you were dead."
