With an Ankō System, Am I the Darkness of the Toyokawa Family?

[Bang Dream + Girls Band Cry + Bocchi the Rock + perhaps more...]

[In this parallel world, all high school students are adults, and every character who appears in this novel is of age.]

[Some details have been changed, and the timeline does not fully follow the original plot. Please don’t read if that bothers you. Also, the Anko elements aren’t the main focus. This is essentially a music novel.]

I’m no good at writing a blurb, so please read the story.

Why? Why did I suddenly die on the spot because I choked while ranting about how terrible the plot of Ave Mujica was? When I opened my eyes again, I had transmigrated into the body of a tool character adopted by the Toyokawa family. Worse, I was given the identity of a second-year high school student and placed in the orbit of Ave Mujica protagonist Toyokawa Sakiko, as her “family inspector.” Now this really is the Toyokawa family’s darkness.

Even more absurdly, I awakened an “Anko System” that can influence the plot and issue side quests. As long as the story is exciting enough, the rewards are mine!

Caught between the family’s mission and a world of girls, bands, and youth, standing at the crossroads of a plot he knows from his previous life, what choice will he make?
