Odd Taxi

Odd Taxi is an incredibly-written anime with an anthropomorphic cast. To many folks, this feels like an adult iteration of Animal Crossing. It tackles multiple adult subjects from gambling to addiction. Every topic is handled with respect. It’s an anime that’s not afraid to show the consequences that occur for individuals who participate in these activities either.

As stated earlier, this anime takes place in a world full of anthropomorphic creatures. They take part in many human activities from watching films to working in government offices. We examine the life of a walrus named Horisho. Horisho works as a taxi driver in his city and didn’t grow up in the best situation. He goes about his day picking up strangers and hearing their never-ending tales.

There’s beauty in the tales these animals share with Horisho. Some may be lighthearted while others may be darker than they’re letting on. Many viewers may resonate with the issues that crop up in these animals’ lives. While there is some comedy thrown into the story, it’s an incredible tale that’ll make you ponder.

With its gloomy setting, realistic villain, and mind-numbing plot developments, Monster is a worthwhile series that will surprise you.

Detective Conan

If Sherlock Holmes were a young boy, he’d be someone like Conan Edogawa. Detective Conan (Cased Closed in the west) is a semi-episodic detective series about a boy named Shinichi Kudo. Kudo is a popular teenager known for his incredible intellect and ability for solving any crime officers throw at him. One day, Kudo meets two men who ambush and drug him with a concoction.

He wakes up and learns he’s transformed into a child. Having to hide his identity from his friend and her father, Kudo changes his name to Conan Edogawa. He travels with his friend and her father, helping them solve multiple cries without their knowledge. His goal is to return to normal while bringing the people who did this to him to justice.

Detective Conan is a mature work, despite the show following a childlike protagonist. Conan tackles numerous cases involving sexual assault, gun violence, drug abuse, and other things. Although it’s mainly episodic, the series does dabble into its main plot involving Conan’s mysterious enemies occasionally. It has many seasons and episodes to its name.

Mononoke knows how to make each tale refreshing and interesting to follow. Nothing feels repetitive as it makes sure to include several unexpected twists to keep you engaged with each one. These tales contain deep messages and provide interesting commentary surrounding human nature. This is because humanity’s actions led to the spirit’s horrid natures in this show.

The show’s art style helps it stand out. However, it can be jarring to people who are akin to watching seasonal anime.

Death Note

Death Note is a remarkable detective series. It mixes its supernatural and mystery elements well to create something worth watching. Fans shouldn’t expect much action from this series.
