After meeting his father Belial as when fighting against Godo Wynn as Geed, Riku was kidnapped by Belial through Chimeraberos and was slowly corrupted by Belial through psychological methods. However, thanks to Laiha and King's interference, Riku escapes from Chimeraberos and brought the battle to Earth before seemingly killing his father for good as Royal-Mega Master upon receiving King's capsule from Laiha. Afterwards, Riku celebrated the victory with his friends and explaining the etymology behind Geed's name.

Riku would later face his father again, whom returns as Belial Atrocious but was easily overpowered until Father of Ultra's arrival allowed him to retreat a while. Soon, with Riku determination and courage, Riku transforms into Geed one last time to face his father. Nearing the end of the fight, Riku sees through Belial's memories and noted how his father truly feels about his banishment, and finally hugging the good Ultra. Riku then destroyed his father for good with his Wrecking Burst and biding farewell as well. After that, Riku restored King's body and sees him and Father of Ultra departing Earth.

  • Riku's actor, Tatsuomi Hamada, previously portrayed Nao in Ultraman Zero The Movie: Super Deciding Fight! The Belial Galactic Empire. In a promotional video of Ultraman Geed, Tatsuomi also mentioned his previous role, now viewing Belial as a father to his character while facing his destiny.
  • His pre-transformation phrase, "Yuugo (Fusion)! Aigo (Protection)! Here we go!", is a pun on the English words, "You go! I go! Here we go!". The latter is even used as the translation provided by Crunchyroll, and for Tsuburaya's Ultra Heroes Expo 2017 posters.

    • If both Human Hosts and Forms are put together, Riku clocks in at the fifth youngest (Including Musashi Haruno, who was 19 in his series), with the aforementioned Mirai being the fourth, Ren being the third, Amui being the second, and finally Yuuto Tamaki being the youngest.
    • In an inversion case to Mirai, Riku is three years older compared to his actor Tatsuomi by the time of the first filming (crank-in).
  • Riku was originally going to have a genetically Grandfather named Alien Rayblood, though this idea was scrapped.
