His surname is Shinoda. In Japan, surnames are listed before given names.
The chief trainer of Aoki Masaru, Kimura Tatsuya, and Itagaki Manabu, Shinoda carries out Coach Kamogawa's tradition of strict training. Aoki and Kimura have even referred to him as "The mud-fighter producing trainer from hell".
Though arguably the least prominent of the main characters, he is shown to still have a good boxer's eye. He is the creator of the inspirational pun Gattsu de Gattsun Gattsun da! (ガッツでガッツンガッツンだ!).
Shinoda has had very little development in the story until very recently as he nurtures Itagaki Manabu. Most notably, his bond with Itagaki is brought to light in the Class A tournament in which he brought out "Itagaki's true potential" against Karasawa Takuzou. Later he was acknowledged by coach Kamogawa as being a good partner for Itagaki after getting Itagaki to calm down by playing Shiritori with him when fighting Saeki Takuma.
