It's one of the entries made by Sandrovich Yabako in the Sandroverse. By Sandroverse, it means a fan term for all his works canonically existing within the same universe and timeline happening independently while dropping easter eggs of another's existence once in a while.
I made a review about Kengan Ashura back in 2020 which is also one of Sandrovich's works.
Nozomi was fired from her underground fighting gig. The only job she had after she quit professional fighting due to an injury. Now unemployed, she meets up with her friends and decided to start an undergound fighting arena on their own. This leads them to meeting Hongou Hina (the poster girl of the series), a high school girl who came from a mysterious organization and drawing in more trouble than Nozomi bargained for.
I like this style of storytelling because it creates continuity over individual stories and shows how one action series is just part of the greater universe.
The overall impression:
It's consistent with what I would expect if Kengan Ashura had a female version of the fighting genre and it did not disappoint. The consistency in the art style is there and I see Sandrovich has improved their visual story telling work through gore, nasty expression, and ink work to prove a point. Isshou Senkin is still a fighting manga that features a diverse cast of femme fatale. Where beauty and lethality blooms in fights contrasted by how brutal human nature can be.
This last image was actually what drawn me into the series because I like horror.
Thanks for your time.
