 Although this movie is filled with lots of shooting rampages, only  two cast members in two scenes were shot using squib (small  explosive with fake blood pack to simulate bullet piercing), those  are Takayo Mimura (qv), who played Kayoko Kotohiki (in the scene  where she was shot by Mitsuko Souma) and Takeshi Kitano (qv), who  played Teacher Kitano (when he was shot by Shuya Nanahara).
