MIAB-414 - I'm the only useless one in a team of elite investigators, so much so that I can be inserted, deeply penetrated, and completely ignored. Miyazuki Ruisa.

I belong to a certain investigative unit. Everyone around me is elite and on the fast track to promotion, while I am low in ability and stand out. And one day… I am ignored by the entire team under the orders of my female boss, Ms. Miyazuki, who always scolds me harshly! But wait a minute? If I'm ignored no matter what I do…! I came up with revenge and started fooling around, exposing my genitals during an important undercover investigation! They clearly show they dislike it! But… you, the instigator, have no choice but to ignore it, right? I became a transparent person even though I'm visible, and I can insert and deeply penetrate as much as I want! Of course, the mission failed and I was captured by the villains, but… I offered my physically fit senior, Ms. Miyazuki, as a substitute and was rescued!
