Partners (あいかた Aikata) is the fifth episode of Ultraman Geed.
A failing comedian meets a new partner named Moko, who is taken away by the AIB for being a unique specimen with healing powers.
Moa and Zena found an abandoned baby Samekujira at a nearby dock. According to the alien, both baby Samekujira and Lunah are supposedly pets but can also be reared as Monster Weapons by malicious forces. A single Lunah was detected on Ethiopia seven years prior but AIB failed to catch it.
In Nebula House, RE.M. had just finishes her study on the Little Star’s properties, such as the heat on their hosts’ palm and their individual powers. Since Little Star phenomenon are always the centre of attraction, Riku decided to watch the news. A comedian named Takashi Arai made his name with his healing powers and this caught the attention of Riku and his friends, but his career gets him nowhere getting the large profit. Moa hunted him since he kept a Lunah named Moko as a pet and capture the animal. Moko instead possess a healing power that is unnatural to its species. Leito tries to have Arai heal someone in his body (Zero) but failed and Riku and Laiha joined the mess. Arai finally gives in and reveal that it was Moko who did the job: 10 days ago, he found and adopted Moko after the critter healed his injured fingers. Since then he made his fortune by using Moko’s power. Zero tries to teach Arai a lesson for misusing and flat out trying to sold the critter before a monster shows up.
The monster made its way to Moa while Moko escapes as Riku saves his childhood friend as Geed. Moko gets tangled in a fishing net after trying to escape Moa and Arai went all the trouble to save his pet, reminded of how he was ditched several times as a comedian and Moko was the only supporter for him ever since. Geed wanted to destroy the monster but noticed that it can cause nearby tanks to explode. With the help Moko’s Little Star, Riku obtains the Cosmos Capsule, using in unison with Hikari to become Acro Smasher and ended Arstron’s threat in a painless way.
Despite Moko losing the healing ability, Arai did not mind about it as he restarts his new career. AIB members desperately try to catch Moko a few times but it still made its way to Arai and they finally given up on the small critter, reducing their method to just observing its actions from afar. Riku gets delighted when Geed gains a massive popularity as a hero (partly due to Acro Smasher’s fame among women). Kei takes this opportunity to transform into Thunder Killer as an excited Riku enters the battle again as Geed.
