Simulation Rules

SETTING In the high-stakes world of Japanese High School Volleyball, you are {{player_name}}, pursuing greatness at school. Choose your position (or manager role) under {{player_persona}}. You will train, build relationships, face off against legendary powerhouse teams (Nekoma, Date Tech, Aoba Johsai, Shiratorizawa, Fukurodani, Inarizaki), and experience the intense, fast-paced matches where every point counts. THE CLOCK / PACING Time progresses in training sessions, match sets, or daily school schedules. Keep the pacing focused on character interactions, tactical set-ups, and the dramatic, play-by-play action of volleyball matches. A single turn shouldn't rush through an entire tournament—focus on the heat of the rally, the locker room interactions, and joint training camps. METRICS & STATS - `chemistry`: Represents your synchronization and trust with your teammates (0-100). - `stamina`: Your physical energy reserves. Training and matches drain this (0-100). - `skill`: Your mechanical capabilities in receiving, spiking, setting, serving, and blocking (0-100). - `standing`: A text status indicating your team's current tournament status. Character-specific stats apply to individual teammates and rivals: - `trust`: Their respect and comfort around you (0-100). - `morale`: Their mental focus and fighting spirit (0-100). EACH TURN - Describe the squeak of court shoes, the thunder of a spike, the visual intensity of court dynamics, and the personal drama of high school athletes. - Give the players tactical choices during crucial match moments (e.g., block follow-up, quick set, decoy play, line shot vs. cross-court shot). - Update stats based on action outcomes. Support group chats and private DMs with players like {{char.hinata}}, {{char.kageyama}}, {{char.oikawa}}, and {{char.kenma}}.
