Sexual violence in Indonesian higher education institutions has become a systemic and recurring crisis, with victims frequently silenced by power asymmetry, bystander effect, and the tonic immobility phenomenon that is often misread as consent. Existing prevention efforts remain largely passive (one-way legal socialization) and rarely train students' ethical decision-making under realistic dilemmas. This study developed and evaluated ELECTORAL, a phygital (physical-digital) board game based on social deduction mechanics, designed to train moral courage and ethical decision patterns among Generation Z university students regarding sexual violence prevention. A QUAL-dominant embedded mixed-methods design was employed, in which data from two focus group discussions (FGD) involving eight students across four universities (USU, Universitas Airlangga, Universitas Pendidikan Indonesia, and Universitas Sebelas Maret) served as the core dataset, supplemented by quantitative one-group pretest-posttest data (N=37) and expert triangulation with a university Sexual Violence Prevention and Handling Task Force (Satgas PPKPT) officer and a family and consumer science lecturer. Thematic analysis (Braun & Clarke, 2006) identified five major themes, most prominently that ELECTORAL mirrors real institutional power dynamics and increases self-reflective institutional awareness among student leaders. The Wilcoxon Signed-Rank Test showed no statistically significant pretest-posttest difference (Z=-1.387, p=0.166) and a low N-Gain (0.15), which qualitative findings help explain through a ceiling effect among participants with prior leadership or advocacy exposure. Expert triangulation confirmed the ecological validity of the game's scenarios while highlighting the necessity of trained facilitators to mitigate psychological risk. These findings suggest ELECTORAL produces meaningful qualitative shifts in institutional awareness that are not fully captured by short-term quantitative measures.
