Heads up
Parent Pro-Tip
Before your teen starts, talk about the story's themes—the game depicts an authoritarian empire that jails political critics, and Monstrum heroes who defy it. Ask your child: 'Who gets to decide who's a criminal?' to turn the fiction into a real conversation.

Bechdel Test?The Bechdel Test checks whether a game has at least two named female characters who talk to each other about something other than a man. A simple measure of representation.— Passes the test
Ys IX features multiple named female Monstrum characters (e.g., Aprilis, Doll, Liliane) who interact with one another about the prison city's mysteries and the Grimwald Nox, beyond just discussing the male protagonist Adol.
Parent Pro-Tip
Playing through Ys IX's Monstrum system—where each character has a unique traversal Gift used to explore Balduq—is a great opportunity to ask your child to map out the city or plan the most efficient route to a dungeon, strengthening spatial reasoning and strategic planning skills that transfer directly to real-world navigation and goal-setting.
What your child develops
Ys IX: Monstrum Nox is a narrative-rich action RPG that offers meaningful cognitive stimulation across several domains. The combat system rewards real-time problem-solving and sharp reaction times, as players must learn enemy patterns, exploit elemental weaknesses, and manage a party of Monstrum with distinct supernatural abilities. Exploration of the prison city Balduq—with its verticality and hidden passages unlocked by new Gifts (traversal powers)—strongly exercises spatial awareness and environmental reasoning. The dense, text-heavy story demands sustained reading comprehension and attention, and the ethical tensions woven into the narrative (Monstrum as outlaws vs. helpers, the empire's political prisoners) prompt genuine critical and ethical thinking. Skill tree management and equipment optimization introduce light mathematical and strategic planning. The game's progressive unlocking of abilities and dungeon difficulty scaling ensures adaptive challenge throughout its 40–50 hour runtime.

About this game
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.
