Since I'm not acquainted with this light novel, it's difficult to name the main characters. However, based on the title, we can assume that the central character is the hero ('eiyuu') from the 'shinwa densetsu' (mythical or legendary). Alongside this hero, there could be other characters such as a female lead who might be a princess or a powerful mage in the isekai setting, and perhaps a sidekick character who provides comic relief and helps the hero in their quests.
Not having read the 'shinwa densetsu no eiyuu no isekaitan light novel', I can't accurately say who the main characters are. But considering the typical elements of an isekai light novel, the hero from the title is probably the main focus. There may be characters like a mentor figure, who imparts wisdom and knowledge to the hero about the isekai world. There could also be antagonists, perhaps a powerful demon or an evil sorcerer who stands in the hero's way and tries to prevent them from achieving their goals in this new world.
