A hilarious review of the anime series where the protagonist gets his head flushed down a toilet and is reborn as the Demon King. Great visuals, excellent voice acting, but slow in some parts. Good for casual viewing.

Have you ever imagined that getting your head flushed down a toilet would take you to another world? The series Today I Started Being the Demon King (Japanese title: Kyo kara Maoh!) makes this a reality! Airing since 2004, this series is a classic isekai that blends comedy, adventure, and character relationships perfectly. Even after nearly 20 years, its charm remains undiminished.

Plot Summary (No Spoilers)

Yuri Shibuya, an ordinary high school student who loves baseball, tries to help an old friend from a gang of thugs but ends up getting his head flushed down a toilet! Suddenly, he is transported to another world called the Demon World, where he is welcomed by handsome officials who declare him their new king. Yuri must navigate palace politics, conflicts between races, and the challenge of returning home, all while reluctantly fulfilling his role as the Demon King. The series focuses on Yuri and his friends' adventures in a fantasy world full of magic, politics, and comedic gags.

Performance and Characters

Voiced by top-tier voice actors like Takahiro Sakurai (Yuri), who brings the protagonist's playfulness and determination to life. Toshiyuki Morikawa (Conrad) provides a warm and reliable voice, while Mitsuki Saiga (Wolfram) charms with a haughty yet caring tone. Every character has a distinct personality, from the stern chancellor Gwendal (Akio Otsuka) to the gentle but sly Gunter (Kazuhiko Inoue). The interactions between characters are the highlight that makes the series engaging, even if sometimes the focus on comedy makes them seem shallow.

Direction, Visuals, and Music

The series is produced by Studio Deen, and for 2004, the visual quality is good. Character designs are beautiful, especially the elaborate costumes in the Demon World. Action scenes are smooth but not outstanding. The music by Yoshihisa Hirano and Hideki Taniuchi (composers for Death Note) creates an atmosphere fitting the fantasy world. The opening and ending themes are catchy, especially the lively first opening. However, some episodes may look dated and less fluid compared to modern standards.

Editorial Analysis

What sets Today I Started Being the Demon King apart from modern isekai is its focus on character relationships and politics within the Demon World, rather than battles or game systems. The series incorporates slapstick comedy and satire of Japanese society through Yuri's perspective. The strength lies in well-developed characters, but the downside is that some parts drag, especially the middle of the first season, which focuses on travel and minor troubles. Nevertheless, for those who enjoy lighthearted comedic isekai, this series is worth watching.

Verdict

For fantasy fans who enjoy comedic isekai without heavy action, <strong>Today I Started Being the Demon King</strong> is a pleasant watch. Despite being a bit old, it remains enjoyable, especially for fans of Japanese voice actors. However, if you prefer concise plots and modern visuals, you may need to adjust a bit. Overall, it's worth watching.
