A lot of popular anime and manga often have protagonists who always save the day - especially in shonen stories where ideals of heroism and friendship take the lead. However, science fiction isn’t always a genre in anime and manga that follow the same trends. With sci-fi stories often exploring ideas and concepts that take humanity’s knowledge and morals to their limits, happy endings aren’t always present for its characters - especially for protagonists who are expected to make bigger and bolder choices for the benefit of themselves and mankind.
