The way the character and story elements were handled are borrowed heavily from Japanese manga and anime tropes, in that many of the premises and representations are larger than life and exaggerated. That can be good or bad depending on the viewer, and their familiarity with those storytelling devices and characterizations. In my opinion, it worked really well with Sanctuary in most instances to dramatize the story and embellish upon plot and character elements. This unique version of the anti-hero to hero origin story and progression hasn't been told in context of sumo before, and you'll be rooting for specific characters and empathizing with them as the season unfolds.
