An American crawfish wrestler from New Orleans and one of a few remnants of the dMp. Under the name "Masakazu Tamura", he would put on a (barely) human disguise and appear at singles bars. Keiko agreed to compensated dating with him, but Rinko stepped in and saved her. He captured Rinko and Mantaro had to fight him. ("The Rigany" (Za Riganī) is a Japanese pun on Zarigani (crawfish).)
