Do Disciplinary Committee Members Dream of Succubi?: Virgin Succubus Achievement Guide

I want to walk you through the hidden achievement Virgin Succubus in Do Disciplinary Committee Members Dream of Succubi? without ruining the story for you. I’ve chased this one more than once on a clean save, and the trick isn’t raw skill — it’s knowing exactly which events will quietly rob Iroha of her chastity and which ones you can safely farm. This guide is written to keep your V-card intact from start to finish.

How to Read This Guide

English isn’t my first language, so if a sentence comes out awkward, that’s on me and I apologize up front. A few conventions will make everything downstream easier to follow. Every event below is named exactly as it appears in the Recollection Room, and the stages carry those same names — so when I say Bookstore Stage 2, that’s the label you’ll find in-game.

How H-Events Actually Work

Understanding the underlying system saves you a lot of reloading, so let me lay it out plainly. H-Events split into categories, and each category has a fixed set of stages. Roughly nine times out of ten, a stage only unlocks when two conditions are met: you’ve already watched or completed the previous stage in that same category, and you’ve advanced far enough in the chapters. There are 5 Chapters plus a final chapter, and the final chapter matters for later planning.

You cannot leapfrog a stage by simply pushing the story forward. Say completing Chapter 3 unlocks Stage 3 of a category — if you never did Stage 2, the next time you interact with that event you’ll clear Stage 2 first, and only the time after that will Stage 3 actually fire.

Later stages are the dangerous ones, because most of them strip your chastity outright. Once that happens the game locks you out of certain categories to keep Iroha “clean,” which is exactly the kind of soft-lock I want you to dodge. A handful of stages can be skipped entirely by winning their minigame — those you can repeat deep into the endgame, as long as you don’t fail. If you do fail one and lose your chastity, heading back to the main menu and loading an earlier save is a perfectly fair fix.

What Actually Counts as Losing Your Virginity

This is the part that trips up almost everyone, so here’s the blunt truth: the game doesn’t care who Iroha sleeps with. It only reads one physical stat on the H-Stats screen. Practically speaking, you can let Iroha act as shamelessly as you like as long as her hymen stays unbroken.

That’s why losing your virginity to inanimate objects is fully possible here.

At the start of a run the event icons make it obvious — a “cracked” heart means the hymen breaks, so I steer clear of those. The problem arrives once you hit 100 Sexual Encounters, because the game forces the Rape Fantasy passive skill onto you, and that turns every icon into the plain, unmarked version. From that point on you can’t tell the safe events from the ruinous ones by sight alone. You could dodge the skill by never opening the skill panel, but honestly that’s more hassle than it’s worth if you’re comfortable with save-scumming or leaning on the cheatsheet below.

My Recommendations for a Clean Run

Assuming you’re on a plain New Game and not New Game+, this is the approach I’ve personally run through twice on a fresh file, and it’s kept my achievement path tidy.

Save constantly. If curiosity or bad luck costs you your chastity, you can always bail to the main menu and reload an earlier slot.
Avoid bad routes. The chapter bosses for Chapters 1–4 won’t game-over you on a loss — instead you’re dumped into that chapter’s bad route and stuck there until you can beat the boss. Most bad routes take your chastity no matter what you do, so dodge all of them except the Chapter 1 bad route, which only inflicts some harassment and spares the important first time.
Do as many H-Events as you safely can — mostly to farm SP, since spending on skills is a far better way to grow strong than grinding levels. Naturally, stick to the ones that don’t break the hymen.
Keep School Order high, or students will jump you. You can dodge them, but it wears thin fast.
Hornymon can’t take your V-Card. No hornymon attack causes virginity loss. The one exception is the H-Event you get by dying inside the Dream Cloisters — that’s a separate matter, so check the Hornymon Defeat entry below if you want the details.
And the rule the original guide shouts in caps, which I’ll happily echo: don’t put the tip in — it’s not just the tip.

The Cheatsheet: Events to Avoid

Below is every H-Event category you need to watch out for, excluding the bad-route events since we’re already skipping those. Chapter 4 gets its own section afterward. Most categories can be pushed to their last safe stage, but the exceptions are the whole point of this list, so follow it closely if you want zero surprises.

Event Category	Safe Stages	What to Avoid
Basic Sex	Stages 1–2	The first two are unavoidable. The third doesn’t count, so grab the optional chests. Avoid completing the Used Tissue questline — you get used, literally, at the end.
Exhibitionism	Stages 1–4	Avoid Stage 5.
Bookstore	Farming-friendly	Stages 3 and 5 only trigger if you fail the apron minigame, so as long as you don’t fail it you can keep doing this event safely. Failing Stage 3 is fine; don’t lose Stage 5.
Blackmail	Stages 1–3	Avoid Stage 4, and therefore Stage 5.
Massage	Repeatable	You choose the course, so you can repeat it endlessly as long as you don’t pick the 4th course or higher.
Bunny Pub	Stage 1	Both stages only complete by failing the minigame. Completing Stage 2 forces Stage 3 next time because the customer cheats to guarantee he finishes raw. To keep farming money and SP, don’t fail the minigame a second time, or just avoid completing Stage 3.
Groping	All stages	Surprisingly safe across the board. Happy train-riding, I suppose.
Sauna	Stages 1–3	Avoid Stage 4, and therefore Stage 5. You can still visit the public bath — just don’t interact with the event while inside.
Poster Photos	Stages 1–2	Avoid Stage 3.
AdultMart	Stages 1–4	Avoid Stage 5.
Girls in the Magic Mirror	Stages 1–2	Avoid Stage 3, and therefore Stage 4.
Guidance Counselor	Stages 1–4	Keep School Order high and these never fire. If you deliberately drop School Order, avoid Stage 5.
Sex Trap	Stages 1–4	Stages 1–4 are unavoidable. Failing Stage 5‘s minigame won’t cost you the V-card, but it hands you a Bad Passive status, so I’d personally win the minigame.
Hornymon Defeat	Stages 1, 2, 3, 5	Triggered by losing inside the Dream Cloister floors. Stage 3 even nets you healing items if you’re low on HP. Avoid Stage 4.
Night Pool	Stage 1	Complete Stage 1, and while inside the Water Park you can touch all other events. Avoid Stage 2, and therefore every Water Park event after the first visit.
Exhibitionist Parading Punishment	Stages 1–4	Triggered by letting Lily’s HP drop to 0. Avoid Stage 5, and I’d turn on auto-heal after finishing Chapter 4.
Killer Move	Stages 1–4	Avoid Stage 5. Annoyingly, this means you won’t collect every Killer Move this run if you’re also chasing that achievement.
Nightmare World	Stages 1–3	Avoid Stages 4 and 5. These don’t require completing the previous one, so stay sharp. More on this in the Nightmare Dungeons section below.
Yuna Debt Repayment	All stages	All safe — it’s not you getting used, after all. Worrying about Yuna’s virginity is a wasted effort; these events happen whether you complete them or not. You’re just watching.

Chapter 4 Survival Notes

I’m not going to narrate what happens during this chapter, because doing so without spoiling it is basically impossible. Straight to the point instead.

If you’re not using the cheatsheet, save before every event. Once you have the Rape Fantasy skill you lose the ability to read the icons, and this chapter is packed with events unique to it. You can also dodge events entirely to pass time by stalling at the infirmary or attending class in your classroom.

After a trigger fires, you’re forced to interact with events, so having the safe ones mapped out is a genuine lifesaver if you’re going in blind. And I don’t just mean the events with CG or the ones archived in the Recollection Room — plenty of in-world events help you once that trigger is active.

Here’s what to avoid:

Skip Gym and Swimming classes.
Don’t interact with the two students on the 3F.
Don’t take the job posting at the Courtyard.

That’s genuinely it. If you’re trying to break the hypnosis, here’s the list of events you can safely grab:

After doing the Art Room event, “dirty” posters appear across the school. Interacting with them builds hypnosis resistance and refunds 1 energy.
On Wednesdays only, you can run “uniform” inspections at the School’s Gate.
School gate: a student stands near a green sign; inside the bike parking you get jumped by a student; to the right of the School’s Entrance another student jumps you.
Gym Entrance: a teacher jumps you the moment you reach the center of the map; a student waits in front of a blue vending machine.
The event inside the Gym is safe. Don’t confuse it with the Gym class event at the running track — that one is not safe.
Courtyard: avoid both heart-icon events. You can talk to the ponytailed student above the library’s entrance.
Library (after obtaining the required “toy”): interact with the boy in green headphones at a table near the entrance; on the library’s right side there’s a safe event; walking left of it, a student beside a ladder can be interacted with; in the bottom-left corner you can get kisses from the student posted there; leaving the library also grants hypnosis resistance.
North Wing 1F: both heart events are safe to interact with.
South Wing 1F: go left and interact with the teacher in front of the Staff Room, then the headphone-wearing student in front of the Boys Bathroom.
South Wing 2F: get kisses from the student in front of the Boys Bathroom; going inside lets you do the event there too. You can enter Iroha’s Classroom to check Yuna’s sprite in the “new uniform,” but there’s no event besides attending class to pass time.
South Wing 3F: talk to the blonde student wearing a mask; talk to the student in the blue tracksuit.

Nightmare Dungeons

Nightmare Dungeons are picked off one at a time. Complete only the ones marked as done in the list below, and steer clear of any that aren’t — including the final, still-undiscovered dungeon.

Unknown Forest (Recc lvl: 10)
Foggy Forest (Recc Ivl:15)
Dim Cave (Recc lvl:20)
Haunted Spot (Recc Ivl: 25)
Underwater Ruins (Recclvl:30)
Misty Sea (Recclvl: 35)
Black Company (Recc Lvl:40)
Office Building (Recc Ivl: ??)
Decrepit School (Recc Ivl: 45)

Conclusion

Virgin Succubus really comes down to patience and paperwork more than anything else — know your icons, save before anything looks suspicious, and walk away from the events that break the hymen. Follow the cheatsheet, keep School Order high, and Iroha walks into the endgame with her chastity intact and the achievement in your pocket. Good luck out there.
