Susumu Hiwatari (火渡進 Hiwatari Susumu) is a minor character from the Bakuten Shoot Beyblade manga.
Personality & Characteristics
As a child, Kai had a very close relationship with his father, a man who enjoyed engineering beyblades. The two played many battles together, delighting the young Kai and making him adore his father. However, when Kai's grandfather, Soichiro Hiwatari, learned of his son's playing rather than working, he dragged him and Kai both to his office at Hiwatari Enterprises. There he issued an ultimatum to Kai's father – to abandon his silly love for toys, or lose his position as heir to Hiwatari Enterprises. Kai's father chose beyblades, voicing a desire to make children smile as his reason.
Kai tried to go after his father as he walked away, but was held him back by his grandfather. At the tender age of ten, Kai took this to be rejection by his father and takes it upon himself to change his attitude. Donning face-paint, Kai begins his quest to destroy beyblades – the toys that 'stole' his father away. While his mother is present at the confrontation in the office, she seems to serve no role, neither aiding nor trying to prevent this rebellion.
Later, during Kai's and Tyson's battle in the regional championships, Voltaire turns up, demanding that the tournament be stopped. At this Kai's father steps in and tells him to leave Kai alone.
