Before Shotaro Ishinomori become a manga artist and eventually the creator of Kamen Rider Series, Shotaro's father against his son to go to Tokyo and tore his artwork and scripts. As a revenge, Shotaro set the true identity of the final boss in Henshin Ninja Arashi is actually the father of the protagonist, Hayate, making it ended up with father vs son tragedy. This was somehow treated as a legacy by staff in Toei and Ishimori Productions and use this concept in Heisei Kamen Rider Series.
