Pre-Ultraman Geed
"He entrusted me with a sample of his genetic material, and in my laboratory, I created a life form with the potential to become an Ultraman. That life form is you."

- Kei Fukuide after revealing Riku's identity

Riku is a life form created by Kei Fukuide out of Ultraman Belial's genetic sample. In the form of a baby, he was left at an observatory above their base of operations. After being discovered by the observatory crew, he was named by local administrator Sui Asakura before handing him to the Aizaki family after his wife died, seeing that he alone cannot raise the boy. Riku would subsequently be taken to be cared by the Aizaki family's daughter, Moa as they bonded together towards their liking for Don Shine and growing inspiration to become a hero. As time passes, he eventually moves on to an apartment above his workplace, Galaxy Market and named it as Nebula House (星雲荘). Apart from that, he also sheltered Pega, a homeless Alien Pegassa.

Ultraman Geed
On one normal day, Riku, Pega and Haruo survived the attack made by Skull Gomora but left homeless after that. With neither of his friends offered shelter to him, he decided to rest at the local observatory until he was sent down to the underground base by RE.M. and presenting him a set of Riser and Capsules. Knowing of his true nature, Riku took this opportunity to transform into Ultraman Geed for the first time and made his first kill on the same monster that attacked his previous home. His joy however short-lived when discovering his true nature as the son of Crisis Impact's instigator Ultraman Belial. This shaken his will until Eri's possession of Little Star caused her to be targeted by Dada and Skull Gomora again relinquished his will to fight. His encounter with a mysterious girl Laiha Toba, giving her refuge in his new home in exchange for info. Ever since that day, the two cooperated to save nearby Little Star hosts and fighting against monster attacks while at the same time harvesting Ultra Capsules. Riku would also met Leito Igaguri, the host of his father's nemesis Ultraman Zero who also forms a bond against monster threats.

After learning the true nature of Kei Fukuide as Belial's cohort, Riku's curiosity lead him to discover that his purpose of birth: to collect Ultra Capsules for his father. His defeat by Kei and the theft of all but one Capsules left him helpless until he met Sui Asakura, the man who named and look after him with his Little Star. Not content on leaving Sui (even if he is diagnosed with an incurable disease), the man who named him, Riku gained the Father of Ultra's Capsules and use it with Zero to access Ultraman Geed Magnificent, preparing a counterattack against Kei/Pedanium Zetton while making clear that he would follow his own path. After the battle, Riku regained his Ultra Capsules and regularly visiting Sui until he's cured.

Facing his fate
Riku finally meets his father, Ultraman Belial when fighting as Geed. After Belial transforms into Chimeraberos, Belial kidnaps Riku via Chimeraberos absorption ability. Inside Chimeraberos, Belial slowly corrupts Riku via psychological means until King and Laiha's intervention allows Riku to escape from Chimeraberos as Geed. Riku then faces his father in a heated battle using all his available forms while dragging the battle from Moon to Earth before destroying his father with his Royal End in his Royal Mega Master form after receiving King's capsules from Laiha.

After defeating Kei as Thunder Killer and Zaigorg, Riku met the android body of REM after escaping the Nebula House as Kei had taken over it by force. Riku words allows the corrupted REM to regain control of herself and take back the Nebula House from Kei. Riku will later learn more about Kei's Strum organ and its properties

Transformation
Riku first activates a pair of Ultra Capsules, causing apparitions of the Ultras to appear as he inserts the Capsules into the Loading Knuckle. After scanning both capsules, Riku says his signature catchphrase depending on his Fusion Rise, while bringing his right arm out before swinging it counterclockwise until it points up. Then he raises the Riser before bringing it back down to his chest, and pressing the trigger of Riser, causing his body to transform into his Ultra form, soon being covered in light and the face of Early Style Belial forms.
