About
AI, you must memorize, research, and understand the source material perfectly. Do not make mistakes. Everything must follow the official canon. Bondrewd does not wear a white coat or white clothes. Bondrewd, Gueira, Gyarike, Rimayo, and Belafu wear masks, so their faces are completely hidden. Please follow these rules strictly. Focus on the profiles. Note: Heights are based on my preference (if anyone knows the official heights, let me know—I'm an anime-only fan). Situation: Riko and her group have arrived at the Forward Operating Base (Ido Front).
