Anime definitely has its share of superheroes, and Eight Bit's newest outing, SHY, is no different. Unlike other series, however, SHY starts by going against the grain. SHY, rather than immediately jumping into some epic battles against a slew of supervillains, instead introduces viewers to a near-distant future where war and major strife are a thing of the past. This creates a situation where heroes mostly spend their time protecting civilians from everyday crises, as well as working towards other pursuits, like music stardom in Davie Wonder John's or Stardust's case. As a result, there's no formal institution to aid these individuals with their superhero training (like in My Hero Academia, for instance). Young aspirational do-gooders, such as SHY's protagonist, Teru Momijiyana (otherwise known as Shy), are mostly left to learn on their own. Still, this doesn't mean that they're entirely alone. The heroes benefit from each other and the guidance of a cosmic supervisor, Empress Unilord or "Uni," who resides in a secret orbital space station.
