Ys IX: Monstrum Nox throws its hero in jail in the first hour and then hands him the keys to the whole city. Adol Christin, the series’ long-running adventurer, arrives in Balduq, a town built around a massive prison complex, and is promptly locked up. A mysterious woman named Aprilis transforms him into a Monstrum, a supernatural being with powers that let him teleport to distant points, run up walls, glide, and pass through solid obstacles. It is a strange premise for a role-playing game, and Nihon Falcom builds a whole city around it.

Balduq Is a Prison With a Town Attached
Balduq is the best idea in Ys IX. The city is dominated by its prison complex, and the game’s structure leans into that. Exploration starts restricted, with barriers separating the districts, and opens up as the story moves. Adol joins five other Monstrums — White Cat, Hawk, Doll, Raging Bull, and Renegade — and together they investigate the prison and defend the city from creatures that appear in a parallel dimension called the Grimwald Nox.
The setup gives the game a reason to care about its walls. Most fantasy RPGs treat a city as a menu with legs. Ys IX treats it as a puzzle box, and the Monstrum powers are the tools that crack it open.
Gifts Turn Walls Into Roads
Each Monstrum carries a traversal ability called a Gift, and once acquired, any character can use it. Adol’s Crimson Line moves the party rapidly to marked locations. White Cat’s Heaven’s Run runs up vertical surfaces. Hawk’s Hunter’s Descent glides. Doll’s Third Eye reveals concealed objects. Raging Bull’s Valkyrie Hammer destroys certain obstacles. Renegade’s Shadow Dive slips the party through narrow passages and beneath barriers.
Falcom built the Monstrum concept after deciding to push vertical movement in three-dimensional spaces. It shows. The Gifts are not cosmetic unlocks; they are the map’s grammar, and the game keeps finding new ways to stack them.
Combat Keeps What Ys VIII Got Right
Ys IX retains the party-based combat, Flash Guard, and Flash Move systems of Ys VIII: Lacrimosa of Dana. The active party holds up to three characters, one controlled directly and the others run by the game’s artificial intelligence. You can switch the controlled character mid-fight.
Each party member uses a slashing, striking, or piercing weapon. Enemies may be vulnerable to one attack type and resistant to the others, which pushes you to rotate characters to match the opponent. Skills burn SP, restored by attacking enemies or regenerating faster while you hold back. A successful Flash Guard — guarding right before an attack lands — negates damage and briefly makes your attacks inflict critical damage. Evading at the same moment triggers Flash Move, which slows surrounding enemies. Boost Mode raises attack and movement speed, cuts damage taken, and unlocks an Extra Skill.
It is a lot of systems, and they interlock rather than pile up. The weapon triangle gives every party member a job. The Flash timing rewards attention over grinding.
The Dandelion Grows With the Cast
The party’s headquarters is the Dandelion, and its facilities expand as characters are recruited. It is a small thing that does a lot of work. A hub that visibly grows gives recruitment a payoff beyond a new moveset, and it keeps the cast present between missions.
The cast itself is the reason to keep playing. Six Monstrums, each with a distinct Gift and a distinct role in the fight, is a lot of moving parts, and Ys IX keeps them all in play. The story was built around the link between the prison, the Monstrums, and the Grimwald Nox. The game’s producer was one of its scenario writers.
He said Aprilis chooses Adol because his previous adventures have made him a symbol of change. After fighting the same conflict for centuries, she hopes his arrival can break the cycle around the Grimwald Nox. That is a clean reason for a series veteran to be the chosen one, and it ties the game to Adol’s history without demanding that players know it.
A City That Fights Back
Here is how the three pillars of Ys IX compare, and where each one lands.
| System | What it does | Verdict |
|---|---|---|
| Gifts | Teleport, wall-run, glide, reveal, smash, phase | The best part of the game |
| Flash Guard / Flash Move | Timed guard negates damage; timed evade slows enemies | Rewards attention, not grinding |
| Weapon types | Slashing, striking, piercing; enemies resist some | Forces character rotation |
The table tells the story. Gifts are the reason to explore Balduq. The Flash systems are the reason combat stays tense. The weapon triangle is the reason the party matters.
Falcom also kept the series’ habit of referencing older entries without making them homework. The Romun authorities question Adol about his travels, and enemies pulled from his memories return. The producer said the team discussed which creatures could come back; some were specified by the scenario, others proposed by developers. The studio regularly considered reviving the ancient Eldeen civilization but often rejected it, because doing so would require players to understand events from earlier games.
That restraint is a virtue. Ys IX is the ninth numbered entry, and it does not ask you to have played eight.
Where the City Runs Out of Room
The criticism that lands is the visual presentation and the restricted urban environment. Balduq is a prison town, and it looks like one — gray, tight, and short on the spectacle the Gifts seem to promise. When your hero can run up a wall, you want a skyline worth climbing. Ys IX rarely gives you one.
The barriers that gate exploration early also sting. They are functional, but they make the first hours feel smaller than the premise. The game opens up, and the Dandelion fills in, but the early stretch asks for patience.
None of that undoes the design. Ys IX takes a series known for field exploration and drops it into a city, then builds movement powers that make the city worth crossing. The Gifts are not a gimmick bolted onto the combat of Ys VIII: Lacrimosa of Dana; they are the reason the setting works.
The Gifts Ranked
Ranked by how much each one changes how you move through Balduq, from the one you will lean on most to the one you will forget you have.
- Crimson Line — Adol’s teleport to marked locations is the fastest way across the city.
- Heaven’s Run — White Cat’s wall climb opens vertical routes no other Gift reaches.
- Shadow Dive — Renegade’s phase through narrow passages and under barriers unlocks shortcuts.
- Hunter’s Descent — Hawk’s glide turns rooftops into a highway.
- Valkyrie Hammer — Raging Bull’s obstacle smash clears the way but does less for movement.
- Third Eye — Doll’s reveal finds hidden objects; useful, but it is a search tool, not a road.
The Score
Ys IX: Monstrum Nox is a confident sequel that solves a problem most long-running RPG series never address: how to make a ninth entry feel like it has somewhere new to go. Falcom’s answer is vertical. Balduq is cramped and drab, and the visuals will not sell anyone on a screenshot. But the traversal is inventive, the combat is sharp, and the six Monstrums give the party a reason to exist beyond damage numbers.
The prison-city premise could have been a costume. Instead it shapes the map, the story, and the pacing. Adol starts the game locked up and ends it running across rooftops, and the journey between those two points is the best argument the Ys series has made for itself in years.
The weak visuals and the tight early exploration are real costs, and they keep this from the top tier of the genre. What remains is a smart, fast, generous action RPG with a movement system worth the price of entry.
