Vise is the definition of a background extra—virgin, normie, permanently eclipsed by a stepsister who saves lives and collects friends like trophies. Nobody takes him seriously until the day he snaps and signs on as a Hollow Investigative. The power flip starts there.
Vise, the Invisible Little Brother
1. The setup leans hard into the underdog POV that fuels the whole route structure. Vise isn't edgy-protagonist material by design—he's an ordinary virgin, a "loser" in his own words, a normie drifting through days where even his social circle is thin. The game opens with him not mattering, which is the point.
2. The pressure comes from the household comparison. His stepsister is the polar opposite: saves lives (medical/paramedic-type framing), popular, competent, the one people actually look at when both siblings walk into a room. Vise has been living in that shadow long enough that "no one takes you seriously" stops being a joke and starts being the premise.
3. What makes this readable for the download page is the relatability-via-pity angle. Players browsing stepsister overshadow MC VN or normie-turned-investigator ADV will recognize the archetype immediately—the question is how far the "Hollow Investigative" gig tilts the balance, and that's what H2/H3 below handle.
"Becoming a Hollow Investigative" as the Lever
1. The title Zone Zero Project and the job title "Hollow Investigative" suggest a worldbuilding layer underneath the domestic setup—something zone/hollow related (likely sci-fi or urban-fantasy adjacent, given the terminology) that gives Vise a reason to step out of the little-brother lane and into a uniform/role with actual weight.
2. The phrasing "you get tired of it" matters—this isn't a recruitment arc where he's scouted; it's a snap decision. That "fed up" energy is what separates the route from a standard charage. The MC chooses to act, which the original blurb flags as the pivot: "Determined, for the protagonist who decides to act, what route lies ahead——?"
3. SEO-wise, the collision with Zenless Zone Zero's "Hollow Investigative Association" is unavoidable, so the page needs disambiguation keywords baked in—Zone Zero Project VN adult, Hollow Investigative Vise stepsister, indie ADV Hollow setting—to keep Google from sending searchers to Hoyoverse wiki pages instead of the download.
Where the 18+ Payoff Lands
1. The game's selling point is the reversal: Vise spends the front half being nobody, then the Hollow Investigative role gives him leverage—authority, danger-pay charisma, maybe blackmail-grade access depending on how dark the routes go—and the stepsister who used to tower over him suddenly has to relate to him on a different axis.
2. Given the "ordinary virgin / overshadowed by savior-stepsister" starter kit, the likely route spread is built around women Vise couldn't touch before the job—stepsister included, plus whoever orbits the Hollow Investigative workflow (colleagues, people he pulls out of zones, maybe the "group date" style chance encounters if the dev borrows that beat). The original blurb doesn't list heroines, but the power-flip structure tells you where the H-scenes aim.
3. For the niche, the long-tail is virgin MC stepsister VN, Hollow Investigative uniform fetish ADV, normie-turned-authority 18+ simulation. The page should flag 18+ upfront, note the domestic-to-field pivot, and make clear this is a project where the MC's growth is the kink—watching someone go from "nobody" to the guy holding the badge.
