Trivia

 * Hanma Yujiro is considered the World's Strongest Man, as well as Baki's Father.
 * Baki's first fight with Shinogi is taken almost move for move from the Grappler Baki OVA released 5 years earlier, except with the character designs of the TV show. However, Suedo, who also appeared in the OVA, does not appear at all during the season.
 * The first arc of the anime series actually takes place later in the manga. In the beginning of the manga, Baki is already grown up.
 * Chapter 25 of The Dangers in My Heart features an unseen, draft of Baki during a work-study group trip at Akita Shoten. Episode 5 of the anime adaptation presents the draft as Baki's fight with Musashi. Later in Chapter 76, Ichikawa's sister Kana uses Yujiro's "Become a woman he can't consume" blessing (While apparently doing Yujiro's iconic stance).
 * Considering that Keisuke Itagaki has been practicing martial arts since he was a teenager, it only makes sense that his greatest work is based all around martial arts.
