He enjoys playing video games. He also has interests in anime, that he was recruited as a bright talent, but secretly he seems to know the connection between Komaru and Umaru.


When he was in middle school he was a shut-in, but was influenced to change his lifestyle by an unknown Japanese individual (possibly Kanau)


Alex browses anime content on the work times, even asking Taihei to fix his computer when it crashes on anime websites.

Alex also gets the same eyes and smile as Sylphynford whenever he gets too excited.

In season 2, episode 8, it is revealed that he talks to Hikari about Umaru's indoor persona.
