Have you ever heard of the Japanese アニメ (cartoon) called 「妖怪人間べム」 (“Monster Man Bemu”)?
It’s basically about three kind 妖怪 (monsters) who want to be human. They learn that they can become human if they protect humans from other evil monsters.
The three kind monsters, 「べム」 (“Bemu”), 「ベラ」 (“Bera”), and 「べロ」 (“Bero”) are frightening-looking monsters but they are able to assume a humanoid form…but even so, they still look like monsters.
And for that reason, they aren’t accepted by most humans. Most people judge them by their physical appearance rather than their character. That is an underlying theme of this series.
This series originally aired on TV in Japan in the late-60’s…before my wife and I were born but we’ve seen re-runs of it.
A well-known line from this show is 「早く人間になりたい！」 (“I want to be a human soon!”)…it can even be heard in the show’s opening theme song.
Here is a YouTube clip of this show’s opening and closing theme songs:
