They’re really challenged… by the case, by incompetent police (it’s not Gunma Prefecture this time though…), by unapproachable instructors, by their own secrecy, by the need for secrecy (up to a point)… it’s good though.

THE HIDDEN TRUTH BEHIND THE ARTIST'S LEGACY
As Kyuu and Ryuu investigates a string of cryptic clues, they decipher a hidden message buried within "Shiunryu" and an old diary. Piece by piece, the enigma surrounding the life and death of the reclusive genius artist Kuzuryu Takumi is brought to light—revealing a truth more personal and haunting than they ever expected.

THE SEALED ROOM AND THE CURSE OF MAYAHIME
A chilling new mystery unfolds as Q Class is faced with an impossible crime: a murder committed inside a room sealed completely by a solid block of concrete. The case ties into an eerie local legend about "Mayahime," a guardian deity said to incinerate intruders with her "Cursed Flames of the Human Sacrifice" to protect the village. Is the terrifying legend real—or is someone using fear as a smokescreen for murder?
