A Deep Dive into The Twelve Kingdoms
For those who don't know, The Twelve Kingdoms is a proper epic fantasy story. It follows Yoko, who starts off as just another ordinary high school student. But then, she gets suddenly exiled to a completely different world consisting of twelve countries. It is not just some lighthearted adventure; the story shows her struggle as she grows up while learning about the lowliness, kindness, and nobility of the human heart. She has to fight dangerous demons and navigate the complex lives of the residents there.
The series is actually based on the famous novels by Fuyumi Ono. The original anime run had a total of 45 episodes, which were first broadcast on NHK BS-2 between 2002 and 2003. The voice acting was top-notch too, with Aya Hisakawa playing Yoko and Taketo Koyasu voicing Keiki, the mysterious figure who takes her to the kingdoms. This show is often cited as a benchmark for world-building in the the twelve kingdoms and nadia discussions among hardcore fans.

Rediscovering Nadia: The Secret of the Sea
On the other hand, we have Nadia: The Secret of the Sea, which originally aired on NHK General from 1990 to 1991. This work is quite special because it is loosely based on Jules Verne's famous books, 20,000 Leagues Under the Sea and The Mysterious Island. It tells the story of the adventures and personal growth of a mysterious and beautiful girl named Nadia, and Jean, an inventive boy who basically falls in love with her at first sight.
The production team for this was quite a powerhouse. Hideaki Anno, who later became world-famous for the Evangelion series, was the general director here. The character designs were handled by Yoshiyuki Sadamoto. As for the cast, Yoshino Takamori played Nadia, and Noriko Hidaka gave her voice to Jean. This anime consists of 39 episodes and is still remembered for its unique blend of science fiction and historical adventure.
