A modern-day doctor who died from overwork was reincarnated as Saito Yoshitatsu, a rival of Oda Nobunaga in his early years.

A life that ends prematurely at 33 and makes him an archenemy of Oda Nobunaga is utterly unbearable for him, so his goal is to hand over his domain to Oda Nobunaga.

And he strives to achieve a long life of ease and comfort.

However, his problem is that he's too afraid to defy his father, Saito Dosan, also known as "The Viper."

To facilitate the storytelling, some non-conventional theories have been referenced.
