|Talent|| Lightning Dribble|
Hayama is of average height and build. He is shown to be very agile and athletic. He has short, blond hair and a pair of oval-shaped eyes with dark pupils. He also has a snaggle tooth in the left corner of his mouth. He wears the blue and white Rakuzan jersey with the number 7.
Hayama is energetic to the point of annoyance. He often fools around carelessly like a child. He is an attention-seeker. Despite these, he has a sense of being vengeful towards his opponents like when Miyaji dribbles past him and Kagami totally dominating him while in the Zone; he requested Akashi to let him mark Kagami one more time for he can't settle down unless he returns the favor. He also takes pride in being an upperclassmen, this is shown when he tells Kagami he forgot to add Senpai after his last name. He is also arrogant as he always wants to destroy those who is up against him.
Hayama was a very strong and talented player in Junior High school and was known for his Lightning Dribble, which earned him the nickname Raijū. However, he was overshadowed by the Generation of Miracles and instead bears the title of one of the five Uncrowned Kings.
Hayama and his team made it through the first round and the quarter-finals with no mention-worthy matches.
Before the Winter Cup semi-finals start, Hayama is seen visiting a sports shop. When Kagami enters the shop and climbs the stairs, Hayama is seen rushing down from it. Unable to stop, Hayama jumps, does a somersault and lands behind Kagami. Hayama apologizes and runs off, but not before Kagami can see his Rakuzan High sweater.
He later appears alongside his team, entering the gym for their match. When Hayama sees Shūtoku High, their opponent, he freaks out and shouts that they look super strong. This annoys Mibuchi. He directs his statement at Akashi and Akashi confirms that they are indeed strong. When the match finally starts, the ball goes to Takao. He is guarded by Hayama and surprises him by passing the ball behind his back.
The match goes on and the first quarter passes by. At the first attack by Shūtoku, Hayama finds himself guarding Miyaji in a one-on-one. He is excited to get some action but is set straight by Miyaji's dribbling and is passed. Hayama is scolded by Nebuya, Mibuchi, and Akashi, and he receives the ball during the counter. Guarded by Miyaji, Hayama smirks and guesses that "three" will be enough. He proceeds to bounce the ball extremely strong and fast, and then dribbles right past Miyaji. He goes up for the lay-up, but encounters Kimura under the hoop. He then performs a double clutch to avoid Kimura, and makes the shot. It is later revealed that his dribble from before only used three fingers. Miyaji is amazed to find out that there are still two stages above that.
The next offense, Hayama passes Miyaji again and passes it through to Nebuya, who later thanks him roughly for the pass. Hayama calls him a muscle gorilla, something Nebuya jokingly takes as a compliment. A counter by Rakuzan follows and Hayama passes Miyaji yet again, only to be blocked by Midorima during the lay-up attempt. Hayama is amazed by Midorima's speed. The first half ends with a tie.
The match continues and Akashi faces Midorima in a one-on-one battle. Akashi overwhelms Shūtoku, resulting in 71 - 51 for Rakuzan. Midorima starts combining his shooting with Takao's passing, slowly closing the gap. Hayama attempts to shoot a basket but misses which results in a Shūtoku rebound and possession of the ball. The players pass the ball to Midorima, who scores again. When Shūtoku regains their determination by slowly cutting into Rakuzan's lead, Akashi shocks everyone by scoring on his own team's basket. He tells his team that this is not the time to relax and that the match is not over yet. He states that if they lose by just one basket, it will have been his fault and that he will gouge out his eyes and give them to his teammates.
When the game resumes, the Rakuzan players appear more serious than before. Hayama gets the ball and scores a basket. The match ends with a score of 86 - 70, as Akashi shuts down Takao and Midorima's combination plays.
During the warm-up, the Rakuzan players settle on their marks, Hayama's being Kagami. All of the starting members are announced onto the court as they bow, wishing for a good match. The tip-off begins and Kagami gets the ball, he scores over Akashi using the Meteor Jam, everyone noticed that he has entered the Zone.
Hayama's speciality is dribbling. His ball control is of such high level, that he actually presses the ball downwards with force enough for it to explode perfectly into a quick cross-over. Because he slams the ball so fiercely onto the ground, it becomes too fast for eyes to follow, making it very hard to steal. If the ball has reached its top speed, it's as if the ball has disappeared. It's also shown the noise his dribble made is loud enough to be heard by spectators that covered their ears.
While his dribbling already is seen to be at a high level, this is shown to be only a portion of his power, as Miyaji observed that he had only dribbled with his three innermost fingers, hinting to two even greater levels of dribbling ability. During Rakuzan's match against Seirin High, Hayama passed Kagami with his power-dribble, this time using four fingers. This indeed seems like another upgrade of his dribbling ability and withholds a fifth level, which he uses against Izuki later on. The five fingers is far different than the other stages because the ball stays still in Hayama's hands even though his body is going for a drive. Then, lightning sparks appear as he starts to dribble, emphasizing his speed and agility. Izuki may have been able to see through his dribbling pattern, but remains unable to match his speed. Kuroko is forced to help on defense, luring Hayama into Kagami's sphere of defense, where he is blocked.
He respects him along with the rest of his teammates. However, he gets shocked from his behavior sometimes such as when Akashi promised to gouge out both his eyeballs as punishment if they lost against Shutoku. After every victory, he feels relief rather than elation because he knows Akashi won't penalize him or his teammates. During the Winter Cup Finals against Seirin, his relationship with Akashi excessively changes. When Akashi doesn't need them anymore, he feels upset. When Akashi breaks down, he is as surprised as the rest of his team. Finally, he is ecstatic when Akashi joins them as their true captain and helps all of them enter the Zone.
Hayama seems to get along with the other Uncrowned Generals of his team. Hayama calls Mibuchi "Reo-nee" (Big sis Reo), because of his motherly nature. Like the rest of the Uncrowned Generals on the team, he seems to have a strained relationship with Mayuzumi as the three might have initially doubted Mayuzumi's abilities as a player
During the Winter Cup Finals, when he first faced Izuki, he thought he wouldn’t be as challenging as Kagami was. However, when Izuki breaks through his technique at full strength, he is shocked. Izuki admits that he knows he’s not stronger, but he is at least smarter than Kotaro. Falling for his taunt, Kotaro carelessly lets Seirin score. However, he calms down and decides to save the one-on-one between himself and Izuki for later. Furthermore, he is the only one yet who has laughed at Izuki’s puns.
