However, his mother found out about it. Kunioka came to Osaka to explain and greet his mother at home, but his colleague Manaka and cameraman HANAMOTO also came along to join him for an Osaka travel location show. Kenta Osaka joins him on what is supposed to be a fun trip, but Saito, the Naniwa Assassin, catches his eye. Will Kunioka be able to enjoy his trip to Osaka to the end, and will he be able to convince his mother of his profession? The first installment of the Kunioka Gaiden series!
