A DNA activist, Kira along with Yoshio Iwayama were sent by their bosses in the form of Team Garcias of DNA to foreshadow the events of Neo Battle Bladers. Brutal and quite hellacious of a Blader, he is among the most powerful of Bladers DNA has to offer with their project, Evil Gene.
Kira Hayama has a very androgynous appearance as with the case of Tsubasa Otori, Teru Saotome, Ryutaro Fukami and Jack. If one were to take one glance, Kira would resemble a female in the person's eyes even though Kira is the opposite.
Kira has quite a large spiked set of lightly-dyed purple hair primarily consisting of five spikes that seem to give off the impression of a crown, much like Zero Kurogane's. Parts of it a bright green, a bright pink and an aqua. He also wears a red hairband with gold pins on them. Kira's right eye is golden and slightly hidden by his hair's drooping spikes whilst his left eye is greatly covered by a black eye-patch that when removed, secretly contains a "Beyblade tracker" that detects where the opposing Bey in a Beybattle is; in a similar manner to Tobio Oike.
Kira's attire also consists of a black jump-suit with red and black straps of gold highlights, greatly cut which reveals a small part of his upper torso as well as his six-pack of abs. Sleeves are also bare and replaced by long red gloves with gold orbs around the end. He also wears a red belt also complimented with these orbs, black pants which is also slightly revealing and black boots with red openings golden latches at the back.
Kira is a Blader never to be underestimated in fights. When battling, Kira shows no doubts or hesitations as he always expects all battles to give the common outcome of him winning each time. This is especially true because as a member of DNA, Kira has the Evil Gene implanted in him which gifts Kira with phenomenal, powerful strength to win almost any Beybattle at any situation. At some points, Kira is even shown to fearlessly intimidate and even ridicule his opponents with some derogatory comments to the point where he undergoes grotesque facial expressions. Kira is also a sadist as he enjoys the harm and pain he inflicts to his opponents, evident by how he injured Shinobu's arm and threw back Eight with strong force that it merely amused him.
In addition to his bizarre approach to Beybattling, Kira seems to show a feminine lifestyle, as evident by his revealing clothes, female profile and body language. Doing things that normally females would do which include, placing their arm on their hip, twisting their wrists forward and bringing their arms backwards.
Beyblade: Shogun Steel
The Dragon-KillerAfter seeing Yoshio fall in his battle against Fire Blader Zyro Kurogane, Kira Hayama ambushes a BeyPark Cyclone Stadium by launching his Berserker Behemoth SR200BWD and smashes Bandid Goreim DF145BS away, giving him this "punishment" as a warning for losing. Looking for a battle at hand, Kira accepts a challenge from the Invincible Salamander, Shinobu Hiryūin and prepared their gear ready as they launch the Beys into battle with Behemoth fighting Ninja Salamander SW145SD.
As the audience watched, Salamander delivers multiple attacks and barrages at the Warrior Wheel and Spin Track of Kira's bey, yet to no avail. Shinobu continues with his Special Move, Phantom Fire Shot to create multiple copies of Salamander to challenge Kira's wit. The Dragon Killer, however, was ahead of this as he activated his eyepatch's "Bey-scanner" to find the real Ninja Salamander, and attacks it. Surprising Shinobu, Kira then unleashes his Behemoth's beast as it frightens Shinobu just in time for Salamander to be knocked out by its Iron Brave, giving Kira the win.
He later approaches Zyro and challenges him to a battle. Later on, he hacks into the WBBA networking channel to speak to a startled Tsubasa Otori and Madoka Amano. After introducing himself, he demands their operations for a nearby arena so their upcoming Synchrome battle could take place. After warning that if they refused to do such thing with the consequences deemed dire, they agreed to complete it despite their suspicious and concerns. Kira then arrives with Yoshio to a canyon outside of Metal Bey City where Zero and his company were waiting. A large rectangular and terrain-esque BeyStadium rose from the ground just to have the others marvel at the sudden change. Kira explains this is the BeyStadium that the WBBA had made according to his orders for the battle.
He and Zyro enter the BeyStadium where they agreed on Synchrome battle as Yoshio and Shinobu exchange their respective Warrior Wheels. After assembling their new Synchrome combos, they start the battle and launched their Beyblades when the others spectated. Kira attacked with Golem Behemoth SR200BWD while Zyro pitted with Salamander Ifrit W145CF. As a stadium of stone and terrain, Zero could not rely on Ifrit's CF Performance Tip which cost him the battle as Kira showed no remorse when his Golem Behemoth continued attacking Salamander Ifrit harshly and despite Zero's using of Diving Crash, Kira used his Special Move Gaia Hammer that summons Behemoth's beast to use a one-hit KO on Ifraid's Beast with its flail. Salamander Ifrit was sent flying out of the BeyStadium, costing Zyro to collapse and giving Kira the win.
Neo Battle Bladers
He then advises Zyro and the gang to retreat to the WBBA after revealing himself as a representative of the DNA organization. Assuming that they gathered all the insight about DNA and the Evil Gene, Kira awaited the national announcement of Neo Battle Bladers hosted by DNA while being presented by the WBBA. Alongside Yoshio, Kira enters the tournament, with his first consecutive wins that included battling Eight while Yoshio fought Kite. As many battles were won, Kira had accumulated enough wins to earn a spot as one of the Best Eight Bladers of the finals. With the remaining Best Eight consisting of himself, Yoshio, Zero, Shinobu, Kite, Sakyo Kurayami, Takanosuke Shishiya and Captain Arrow, Blader Gai announced that Kira would face off with Kite as the second battle of the Best Eight.After
Yoshio's loss at the hands of Shinobu and his newly found Special Move, Blazing Ring Shot, it was time to commence the battle between Kira and Kite. While Kite was given Eight's Orochi Warrior Wheel to help him win, Yoshio does the same with his Golem. Launching their Synchrome Beyblades into battle, Kira's Golem Behemoth clashes with Orochi Leviathan. Because of the Syncrome bey's perfect wheel and fighting Kite to his fullest potential, but with his Behemoth's Gaia Hammer that unleashes its Beast against Leviathan's. Despite Kite's determination, Kira showed no fear when his own Special Move causes a great explosion that ricochetes Orochi Leviathan to a dent far above that cost Kite the loss and allowed Kira to pass on through the semi-finals.
The Ultimate Emperor of Destruction: BahamooteIn the DNA headquarters, Kira is battles the other DNA bladers. One by one, he first defeats Yoshio, then Genjuro, then Spike, and finally Captain Arrow with a easy win effortlessly. Then he looks at Behemoth and says that though its the best stamina-type ever created, he wants something more to battle with. He then drops his former bey and Yoshio walks over to him. He asks if he is sure that he wants to get rid of Behemoth which Kira accepted and walks away.
After Zyro defeats Sakyo, Kira and Shinobu's battle begins. Before the battle starts, Kira unveils his newest beyblade: Gladiator Bahamoote SP230GF. Everyone is suprised, even the Garcias. Shinobu does not care as they launch their beys and begin the battle. Salamander attacks right away as Shinobu summons more strength and activates his Special Move; Blazing Ring Shot. But Bahamoote is left undamaged. Kira then unleashes a powerful dark-violet aura of darkness and uses a new Special Move; Gladiator Demolition, which not only crushes Saramanda, but completely destroys the entire BeyStadium, leaving an injured Shinobu.After the battle, the Garcias confront Kira, wanting to know why he is not using Begirados like they had planned. Kira explains that he threw Begirados away and that he wanted something more to battle with. The Garcias are suprised to see that Yoshio and Merci side with Kira. Then Spike, Genjuro, and Captain Arrow jump out and launch their beys. Kira launched and defeats them all at once, proving the power of Bahamdia once again. Then Kira and Yoshio lock the Garcias in one of the rooms in their headquarters.
Kira goes on to the final battle against Zyro, confident that he will win. They launch and the battle begins. Zyro stands strong and uses his signature move Burning Upper. Bahamdia survives this easily and Kira is impressed with Zyro's tactics. He then decides become more serious. Then Kira uses Gladiator Demolition, but Ifraid still spins. Kira is shocked, but continues to battle. Then he uses Gladiator Demolition again and launches Ifraid high into the air, But Zyro is not depressed, then Ifraid comes diving down. Zyro uses the his spirit's bond with his friends to create a new special move: Burning Tornado Fire. Kira commands Bahamdia to defend and the collision causes a huge cloud of dust. When it clears, Bahamdia has stopped spinning and Ifraid is barely spinning. Zyro is now the number on blader in Japan. Then Zyro asks for Kira's friendship, but Kira does not accept and walks away, defeated with Yoshio.
