Calling all 20-somethings! A roundup of nostalgic anime [2000s–2010s] (31–40)
Pocket Monsters

It feels like the Pokémon franchise, which began as a Nintendo game, became a social phenomenon in large part thanks to the anime that started airing in 1997.
The story of the protagonist, Satoshi (Ash), journeying with his partner Pikachu to become a Pokémon Master sparked a spirit of adventure in many children.
The encounters with unique Pokémon, the heated battles, and the bonds with friends are the kind of elements that stir the heart no matter the era.
With each new game release, the anime weaves in fresh elements, and at times looks back on the past—storytelling made possible by its long-running history, which is a big part of its appeal.
Nodame Cantabile

Many people in their 20s today may have watched Nodame Cantabile when they were in elementary school and, because of it, became interested in classical music or even started playing instruments themselves.
Based on Tomoko Ninomiya’s hugely popular manga, the animated series Nodame Cantabile aired on Fuji TV’s Noitamina block from 2007 to 2010 across three seasons, and became a major hit centered on classical music.
It’s also a rare case where both the live-action and the anime adaptations were successful.
Despite its classical music theme, the show is anything but stuffy: from the protagonist Nodame on down, the wonderfully eccentric characters are irresistibly charming, and the series brilliantly lets you learn about classical music while laughing out loud.
It’s enjoyable for all ages, so if you’ve just become interested now, be sure to check it out!
Fruits Basket

Based on the manga by Natsuki Takaya, Fruits Basket is a work whose popularity is clear from the fact that it was adapted into an anime in 2001 and then remade in 2019.
The story follows the protagonist Tohru Honda, who ends up living in the home of her classmate Yuki Sohma due to an unexpected turn of events, and gradually learns the secrets of the Sohma family through their daily life.
The unique characters themed around the Chinese zodiac, as well as the way each one confronts their personal struggles, are key points of interest.
Its touching portrayal of family bonds and personal growth resonated with a wide audience and earned broad support.
Detective Conan

Detective Conan is a mystery anime about Shinichi Kudo, a high school detective who is forced into a child’s body by a mysterious organization and solves numerous difficult cases as elementary schooler Conan Edogawa.
Since its debut in 1996, it has been loved by audiences of all ages as a nationally beloved series.
In addition to its authentic mystery elements with intricate tricks, its distinctive characters are a major draw, and the story’s shifts from comedic to serious keep viewers engrossed.
Not only the TV anime but also the feature films attract attention, giving the impression of a franchise whose momentum shows no sign of slowing.
Magic Knight Rayearth

The anime Magic Knight Rayearth is a fantasy series based on CLAMP’s manga.
It depicts three girls who are summoned to an alternate world called Cephiro and set out on a journey as Magic Knights to save it from crisis.
Set in a realm of swords and sorcery, the story’s appeal lies in how the girls fight and grow.
Another highlight is the beautiful artwork characteristic of CLAMP’s works; the delicate designs further accentuate the worldbuilding.
Along with its theme song, “Yuzurenai Negai” (Unyielding Wish), it’s a title that has surely left its mark on anime history.
