A new frontier for the 4-koma prince, Naoki Shigeno!! A Sengoku gag that revolutionizes 4-koma is finally released!! There have been several 4-koma manga featuring historical figures as variations of character goods since long ago, but a work that vividly and delicately depicts Nobunaga's battles for unification while incorporating the latest research results might be unprecedented even in story manga. The skill to vividly portray the tragedies of the battlefield while properly dropping the punchline as a 4-koma is the true essence of Naoki Shigeno as a veteran 4-koma author.
