Popular sequels like Re:ZERO -Starting Life in Another World Season 4 and Wistoria: Wand and Sword Season 2 were highlights, alongside several exciting new series. One standout show was Witch Hat Atelier, a fantasy anime based on a well-regarded manga.

Spring 2026 had a lot of new anime, but some really great shows didn’t get the attention they deserved. While a few managed to gain some recognition, they weren’t as popular as the biggest hits. Here are seven fantastic, underrated series that are just as good as any popular anime released lately – be sure to check them out!

7) Nippon Sangoku: The Three Nations of the Crimson Sun

Don’t miss this fantastic anime series, now available on Prime Video! It’s quickly becoming one of the best of the last ten years. Based on a popular manga, the story is set in a future Japan that has been completely changed. During the Reiwa Era, the country fell apart due to war, disasters, and widespread corruption.

The country falls into chaos and civil war, splitting into three powerful factions known as the Three Kingdoms. The story centers on Aoteru Misumi, a humble government worker who rises to become a renowned military leader. He sets out on a mission to end the conflict and restore unity to Japan.

6) Ace of Diamond Act II

The popular anime series Ace of Diamond is back on Crunchyroll with a new season, over six years after the original finished airing. Based on a manga by Yuji Terajima, the show is a well-regarded sports anime. While the first season was animated by Madhouse, this sequel is a collaboration between Madhouse and Production I.G.

This story continues with Eijun Sawamura as he starts a new baseball journey at Seido High. He’ll face tough competition from the nation’s top players while navigating the challenges and thrills of this next chapter in his career.

5) Go For It, Nakamura-kun!!

This funny anime, aimed at a male audience, is adapted from a manga created by Syundei in 2014. It took ten years for the story to be made into an anime, and you can now watch it on Crunchyroll. The story follows Okuto Nakamura, who instantly falls for Aiki Hirose and desperately wants to be his friend, but his attempts always fail.

Nakamura did get his crush’s attention, but it didn’t go as well as he’d hoped. He had several opportunities to improve things, but his own unrealistic beliefs are holding him back.

4) Agents of the Four Seasons: Dance of Spring

The beautiful anime series available on Crunchyroll is adapted from a light novel by Kana Akatsuki, the creator also known for the popular Violet Evergarden from Kyoto Animation. The story takes place in a world that was once perpetually winter. Because this existence felt isolating, Spring was created. Eventually, the world desired even more variety, leading to the birth of Summer and Autumn. Those responsible for maintaining the seasons are called Agents of the Four Seasons.

Ten years ago, Hinagiku, known as the Agent of Spring, vanished, and with her, spring itself disappeared. Now, after enduring incredible difficulties, she’s returned to bring spring back to the world. Throughout the years, a legend has grown about a connection between Hinagiku and Winter.

3) Akane-banashi

Although it started with a lot of potential, Akane-banashi is a hidden gem among Shonen Jump series. Because the story centers around Rakugo – a traditional Japanese art of storytelling – it hasn’t become widely popular outside of Japan, though it’s recently gained a small, devoted following.

The anime follows Akane Osaki, a high school student determined to become a skilled Rakugo performer. She’s been dreaming of this since she was a child, and she also hopes to find out why her father was suddenly forced to leave his position years ago. It recently became available on Netflix.

2) Mission: Yozakura Family Season 2

Let’s talk about Mission: Yozakura Family, another great series from Weekly Shonen Jump. It recently returned for a second season on Hulu. The story follows Taiyo Asano, a boy who became shy and withdrawn after a tragic car accident took his family. His only consistent friend through it all has been Mutsumi Yozakura.

When Taiyo and Mutsumi run into serious problems because of Mutsumi’s family, their school principal, Kyoichiro Yozakura, proposes a surprising solution. He thinks Taiyo might be dangerous to Mutsumi, and the only way to protect them both is for them to get married.

1) Kill Blue

This exciting manga series, created by the author of Kuroko’s Basketball, recently concluded in September 2025, with an anime adaptation announced around the same time.
