Minami Kawanami operates within the Foo Fighters organization, actively participating in hostile takeovers of card shops and embodying a confrontational, disruptive presence. His personality during this phase blends arrogance and a readiness to inflict harm with underlying cowardice, prompting him to flee when encountering serious resistance or pain. A critical cardfight defeat against Toshiki Kai shatters his former demeanor, triggering a drastic behavioral shift. Post-loss, Minami adopts canine-like mannerisms and enters a state of subservience to fellow Foo Fighter Asaka Narumi. Asaka treats him explicitly as a pet, enforcing this role through a dog collar and leash under her direct control. This altered state defines his subsequent appearances. Later, Minami undergoes transformation into one of the early PSYqualia Zombies. In this condition, he assists Suiko Tatsunagi's efforts to seize control of Fukuhara High School, continuing his involvement in antagonistic activities despite his altered mental state. Physically, Minami possesses long, unkempt white hair and red eyes. His typical attire consists of a distinctive red leather suit featuring grey accents and zippers, worn over a black shirt. The dog collar mandated by Asaka remains a consistent element of his appearance.
