|This article is about a/an character in Kamen Rider Ex-Aid.|
Rensuke Natori (名取 蓮介 Natori Rensuke) is the victim of the Aranbura Bugster.
Rensuke was going to be married to Asami Goda until his fiancee called off the wedding. Shortly after, the Bugster infection causes him to collapse. Emu and Asuna arrive, but Hiiro shows up and diagnoses him first; the Aranbura Bugster speaks through him before he is taken over by the infection and turns into his Bugster Union form. Hiiro and Emu become Kamen Riders Brave and Ex-Aid Level 1 and destroy the virus form, but before they can defeat the Aranbura Bugster who separated from him, Kamen Rider Genm interrupts, letting Aranbura escape.
Because the Bugster wasn't defeated, Rensuke is still being affected, and is slowly fading away. Upon hearing his story, Emu hypothesizes that the stress from his fiancee breaking up was what "triggered" the Bugster infection to well up. He also discovers that she only broke off her engagement with Rensuke because she didn't think she was good enough for him. After the Aranbura Bugster is tracked down and defeated by Ex-Aid and Brave, Rensuke recovers and uncancels the marriage.
The Bugster Union (バグスターユニオン Bagusutā Yunion) is the monster form of a Bugster-infected patient when the virus first flares up. When a Bugster-infected patient experiences enough stress, the Bugster Viruses inside multiply rapidly and overtake the patient's body, forming a giant orange virus form around it; the Union's shape seems largely irrelevant to the Bugster's appearance. Bugster Unions can only be defeated by a Kamen Rider in Level 1; the reason why is unexplained, though it may be because other Levels are too strong and may injure the patient inside the Union.
Behind the Scenes

- Though partly resembling a squid, his giant virus form also resembles the real world bacteriophage virus.
- If the other Giant-variant virus forms are any indication, this could also be a reference to wall torches/chandeliers of medieval castles, which would pair with the theme of the Aranbura Bugster.
