What is real... is defined by what is not.
Who one is... is defined by who one isn't.
To move forward, one must accept these truths.
Yes, in this prison — this cradle — my dreams and reality became one.
~ Excerpt from Prison of Balduq
Ys IX: Monstrum Nox takes place in Balduq, northeast of Esteria in the Gllia region, under Romun control. Balduq is known as "the prison city" for its large prison facility inside the town and its architecture featuring high walls as a result of being built upon the fortified era. The city is an important nexus for transportation in the region, resulting in a wide range of inns, bars and trade centers. In more recent years, public facilities such as theaters and baths have started to be developed too.
In more recent years, rumors of enigmatic individuals called "Monstrums" are said to have started appearing. The Monstrums are said to possess unique supernatural abilities, some of them seem to be helping the poor and helpless, while others are outlaws up to no good. This dichotomy has earned them both notoriety and ire from the many denizens of Balduq.
Balduq Prison, located at the edge of the city, is supposedly the largest prison facility of the Romun Empire. Originally, it was a fortress built to protect the Romun border, but it has recently been repurposed as a prison facility. Featuring only one entrance through a drawbridge, and surrounded by steep rock walls and deep moats, it is said to be inescapable. The townsfolk do not hold the prison facility in high regard, as the facility is also used to detain critics of the empire and political prisoners.
- Main article: Ys IX: Monstrum Nox/Characters
- Adol Christin / Crimson King: A peerless adventurer whose more than one-hundred travelogues document his journeys for future generations to discover. As a key suspect in the disappearance of the Romun Fleet on the Atlas Ocean, Adol was apprehended by Romun soldiers at the site of his next adventure: the Prison City of Balduq. While attempting to escape incarceration, he came across a mysterious woman with a gun, setting into motion his involvement in the strange happenings of the Prison City and its Monstrums.
- White Cat: She fancies herself a chivalrous thief, stealing from the wealthy and giving to the Shantytown, where the poorest in Balduq reside. She makes frequent contact with the city's denizens, and is often seen making ostentatious public displays throughout town. Her nimble, cat-like physique makes her particularly suited for speedy, agile attacks.
- Hawk: Known in Balduq as the "Feral Hawk," a maniac who tests his skills by assaulting others in the name of "divine retribution." A vicious drinker with a penchant for violence, the Hawk enjoys instigating fights with others, and is prone to losing his temper over minor squabbles. He is the least cooperative of the Monstrums, and has proven to be a handful even for them.
- Doll: A Monstrum with the appearance of a flawlessly crafted antique doll. She possesses the ability to perceive that which normal humans cannot. The Doll conducts herself in battle with a manner one could only describe as uncanny, and her origins are a mystery to even her fellow Monstrums. Her encounter with Adol seems to not be without some sort of purpose...
- Raging Bull: She specializes in pure, raw power. A dynamo in battle, she wields an enormous war hammer to smite her foes. Unlike the White Cat and the Hawk, the Raging Bull is far more down-to-earth, and prefers mediating the Monstrums' quarrels to involving herself in criminal activity. Rumors state that she has family living within the Prison City. Whether that's true or not remains to be seen.
- Renegade: A Monstrum whose ragged vestments and unconventional appearance lend him his name. An ardent pessimist, the Renegade rarely shows himself in public. As such, few in Balduq can profess to have ever actually seen him. He seems to be very knowledgeable about the history of Gllia, as well as the Prison City of Balduq itself...
Ys IX: Monstrum Nox largely builds on the gameplay foundation of Ys VIII: Lacrimosa of Dana, where players control multiple main characters that can be switched between on-the-fly, each with their own play styles and unique skills.
- Skills: Consume SP (Skill Points) to unleash a character's unique skill attacks. SP will restore when you land hits on enemies, but it can also quickly regenerate while not attacking. Later in the game, Valkyrie Hammer can also be used to restore SP.
- Boosting: A returning mechanic from Ys: The Oath in Felghana and Ys Origin. It can be activated once the Boost Gauge is at least half-way full, and continuously drains with time. In addition to increasing damage dealt and reducing damage taken, Boosting also increases attack and movement speeds, allowing for bigger and better combos to be performed.
- EXTRA Skills: Can only be activated during Boost mode. EXTRA Skills boast tremendous power and massive ranges of effect, but they will instantly deactivate Boost mode.
When the player begins a new game, the difficulty can be selected from "Easy," "Normal," "Hard," "Nightmare," "Inferno," or "Lunatic." The difficulty can be changed at any time. The difficulty statistics are:
-  Lunatic has the same multipliers as Inferno, but damage received is doubled.
- Monstrum Gifts: The supernatural powers of the Monstrums, called Gifts. Each Monstrum has their own unique Gift, they can be activated anywhere in the city, field, or dungeon, and they're useful not only for battling enemies, but also for clearing dungeons and exploring the city. As you gain the cooperation of the Monstrums that appear in Balduq, the number of different abilities you can activate will increase.
|Crimson King||Crimson Line||Fly to the nearest pre-determined spot||10% per use|
75% on enemies
|White Cat||Heaven's Run||Run up vertical walls||30% per second|
|Hawk||Hunter's Descent||Glide across a short distance||20% per second|

- Sacramentals: Special items known as Sacramentals can be obtained through exploring or when certain conditions are met. By equipping Sacramentals, the entire party will receive a special benefit that can greatly aid during combat or traversal.
- Azure Petals: Blue flower petals scattered throughout Balduq are said to bring fortune and joy to those who gather them. Deliver them to Marguerite in the city to earn various rewards. For some reason, Marguerite's manner of speech seems to change upon reaching certain milestones.
- Graffiti: Old scrawlings found in various locations throughout Balduq. Examine and report them to Professor Vallin, the anthropologist, to earn various rewards. Strangely, in addition to offering valuable insights on the past, certain special graffiti will bolster the Monstrums' stats when examined.
- Grimwald Nox: The Grimwald Nox is an alternate dimension in which the Monstrums gather to fend off countless hordes of evil spirits, known as Lemures. Eradicating the Lemures and dispelling the Grimwald Nox will release various barriers placed throughout Balduq, allowing you to explore more locations throughout town.
- Connection with other games: If the player has a save file of Ys VIII: Lacrimosa of Dana or Ys: Memories of Celceta, they can receive an in-game bonus for each save they have in their system. Nintendo Switch version players can receive both bonuses with a save file of Ys VIII only. Each of these games don't need to be completed for the bonus, only the save file on the system is required.
|Item Received||Stats||Required Save File|
|Old Seal Ring||STR/DEF +15
Critical Rate +30%
|Ys VIII: Lacrimosa of Dana|
|Celcetan Wreath||DEF +10, HP +200
|Ys: Memories of Celceta|
There is a variety of paid cosmetic DLC such as costumes and attachments.
