Case Closed: One Truth Prevails – The Mirapolis Investigation

The Mirapolis Investigation starts with a comfortably familiar Case Closed setup: Conan, Richard Moore, Rachel, and the Junior Detective League arrive at a newly opened amusement park, then a murder abruptly turns the outing into a case. Wandering the hotel, annex, gym, and courtyard while asking questions gives you the right detective rhythm—slowly turning a tourist destination into a crime scene.

Its best idea is also its harshest. The clue-link sequences ask you to build the correct chain of hints from Conan’s notebook, but one wrong choice wipes out every Link Point earned in that attempt. Fans who enjoy carefully retracing evidence may find that pressure satisfying; anyone wanting a breezier anime mystery may find the punishment disproportionate to the investigation.

Gameplay

You spend the opening stretch steering Conan through Mirapolis from a third-person view, speaking with characters and getting a feel for its separate locations. The hotel, annex, gym, and courtyard give the case a contained, easy-to-grasp footprint. Rather than racing through action scenes, you are expected to pause, question people, and notice what might matter later.

Evidence analysis occasionally shifts into point-and-click investigation, which suits a Detective Conan game well. These are the moments where the game most directly asks you to think like Conan instead of simply moving him to the next conversation. The structure is straightforward, but that simplicity can be welcome when you want a licensed mystery that keeps its attention on collecting leads and connecting them.

The clue-link system is where the investigation becomes demanding. You select a chain of clues from the notebook, earning a Link Point for every correct placement. Make one mistake, though, and the entire run of Link Points disappears. That all-or-nothing rule creates real tension when you think you have the case figured out, but it can also turn a single bad selection into a deflating setback. Take your time and review the clues before committing; this is not a system built for guesswork.

Mini-games add another route to points, which can be spent on bonus content, while Link Point totals can also unlock extras. That gives completion-minded fans a reason to engage with more than the central case. Still, the core question is whether you enjoy the clue chains themselves. If that notebook logic clicks with you, the bonus chase is a pleasant extension; if it does not, more point targets will not soften the penalty for a wrong answer.

Graphics

The game follows Conan from a behind-the-back, third-person camera as he moves through Mirapolis. The hotel, annex, gym, and courtyard provide the main backdrops, and the camera choice keeps the focus on physically exploring those spaces and locating the next person or piece of evidence.

Story

This is an original Case Closed mystery rather than a retelling of a manga or television case. Richard Moore is invited to Mirapolis’s opening ceremony as a publicity draw, bringing Rachel, Conan, and the Junior Detective League along for what should have been a simple park visit. A murder soon changes the tone, putting Conan back in the familiar position of investigating while hiding behind his child identity.

That setup is exactly the sort of compact, location-based premise the series handles well. Mirapolis is useful because everyone begins in one shared destination: guests, hosts, and potential suspects can all plausibly cross paths. You are not being asked to absorb a sprawling adventure before the mystery begins; the case arrives quickly and gives the park a darker purpose.

Fans of the franchise will appreciate the recognizable group around Conan and the fact that the mystery is built for them rather than pasted onto an unrelated game. Newcomers can follow the immediate murder investigation, although the premise carries more weight if you already enjoy Conan’s double life and the Moore family dynamic.

Overall Experience

The Mirapolis Investigation is a modest detective adventure with a strong fit for its source material. Exploring a closed set of park facilities, talking to characters, studying evidence, and assembling clues all point toward the same fantasy: you are helping Conan untangle a case, one observation at a time.

Its biggest frustration is also the feature most likely to separate devoted mystery solvers from casual fans. Losing all Link Points over one incorrect clue choice is severe. For some, that makes a correct chain feel earned; for others, it makes the process feel less like deduction and more like being punished for an imperfect recall of the notebook.

Give it a chance if you want a Case Closed story that asks for patient attention and you can tolerate retrying the logic-heavy parts. The payoff is a self-contained Conan investigation with familiar faces and a fitting setting, not a relaxed amusement-park romp. If you mainly want an easygoing licensed adventure, the clue-link stakes may test your patience more than your detective instincts.
