Tetsurou Yoshinogawa was a chef who had a cooking show on television in the anime. Taiki was invited to be a special guest on the show, and he brought Makoto along to demonstrate how to bake a strawberry shortcake. Usagi invited herself along, however, and jumped into the show to "help" them cook, with disastrous results. Fortunately, Tetsurou was prepared with a pre-made cake and the rest of the show proceeded smoothly.
After it was over, however, Tetsurou was confronted by Sailor Iron Mouse in the hallway outside the studio, and she removed his Star Seed. It turned out to be a blank, and he transformed into the Phage Sailor Chef. He was returned to normal by Eternal Sailor Moon.
- Tetsurou's first name is pronounced the same as another Japanese name which is written with a different character, 鉄郎 (lit. "iron son"). It is likely that his name is a pun referring to Iron Chef.
