Young orphan Riko dreams of following in her mother’s footsteps as a Cave Raider to excavate the Abyss’ secrets. When she meets a robot boy named Reg, they descend into the terrifying abyss together.

Hunter x Hunter anime gradually unveils a larger world with inventive Nen techniques, fantastical creatures like Chimera Ants, and a criminal underground network. Watching Gon and friends unlock the mysteries about Ging’s exploits as they advance as Hunters makes for delightfully engrossing worldbuilding for the fans.

6) Dr. Stone

Dr. Stone constructs an intelligent “stone world” where Senku plays by realistic scientific rules to slowly achieve his end goal of reviving humanity. Watching him making things like ramen, light bulbs, and carbonation from scratch shows thoughtful worldbuilding on survival without modern amenities.

7) Mushishi

In an undefined period resembling Japan's Edo to Meiji periods, mushi are primitive lifeforms only visible to some that cause mysterious phenomena like diseases without being fully understood. Mushishi Ginko has studied mushi for years, traveling to Japan to research mushi and aid those suffering mushi-related occurrences using his spiritual abilities.

A slice-of-life episodic series, Mushishi’s volume of creative tales about Ginko confronting new mushi with different abilities crafts a folkloric atmosphere where humans still grasp to comprehend the mushi sharing their natural world. Its minimalist, naturalistic watercolor visuals beautifully match the rural countryside's mystical mushi theme.

With intricate magic mechanics, cooking/crafting systems, and city-building simulated from actual MMORPGs, Log Horizon translates typical RPG game elements into a fleshed-out living, breathing society shaped directly by the gamers’ actions trying to adapt.

As a decades-long generational saga still unfolding, One Piece’s enormously expansive worldbuilding creates an unrivaled vibrant pirate-fantasy universe.
