About This Game

Yiguan: December is a visual novel combining inn management, character development, mystery, and romance with multiple heroines.

You take over a mysterious entertainment house in a fog-shrouded town. By day, you manage the house and help its residents grow. By night, familiar streets reveal an unsettling side. Recurring dreams, hidden memories, and the ritual awaiting you in December point toward the truth behind a repeating cycle.

【Management and Character Development】

Plan your monthly activities, train characters, arrange rest, manage the teahouse, and upgrade facilities. With limited action points each month, you must balance income, character growth, relationships, and investigation.

【Character Stories and Relationships】

Each heroine has her own personality, secrets, and awakening storyline. Through training, exploration, dialogue choices, and relationship events, you can learn about her past and unlock further story developments and abilities.

【Heartbeat Conversations】

Each month, choose a heroine and select from predefined dialogue options. Different approaches can affect affection, while some conversations offer clues for your investigation and puzzles.

Character replies use prewritten text included in the game. These conversations run locally, without an AI service, free-text chat, or live-generated responses.

【Night Exploration and the Cycle】

Explore the town after dark, uncover hidden clues, and face dangerous encounters. Resources gathered during the day and your characters' abilities help prepare your party for exploration and year-end battles.

Piece together the town's secrets and discover what lies behind the cycle.
