Summer 2025 is stacked with some of the most hyped anime releases we’ve seen in years. Whether you’re catching up on fan-favorite series returning for their next arc or diving into bold new adaptations, this season is set to deliver heavy-hitters across every genre. From supernatural slugfests to high-octane science shenanigans, here’s your definitive Foolieo.com guide to the top anime you don’t want to miss this summer.
1. Dan Da Dan Season 2 – The Paranormal Escalates
The cult-favorite Dan Da Dan returns, and the stakes are weirder—and wilder—than ever. Season 1 blew minds with its offbeat blend of sci-fi, horror, and absurdist humor. Now, Season 2 throws us deeper into the battle between aliens, ghosts, and hormone-fueled teenagers with psychic powers.
Expect sharper animation, freakier yokai, and even more outrageous character development. Studio Science SARU is once again at the helm, and if early trailer buzz is any indication, we’re about to witness peak animation insanity. If you liked Mob Psycho 100 or Jujutsu Kaisen, this is your chaotic summer ride.
2. Kaiju No. 8 Season 2 – Humanity vs. Monsters Reignites
One of last year’s breakout hits, Kaiju No. 8, is back and ready to stomp the competition. Season 1 ended with Kafka’s secret hanging by a thread and the Kaiju threat growing bolder by the day. Season 2 picks up with the stakes at an all-time high as the Defense Force begins to question who they can trust—including Kafka himself.
What makes Kaiju No. 8 so special is its unique blend of character-driven storytelling and brutal kaiju battles. Fans of Attack on Titan and Tokyo Ghoul will love how this show balances action and emotion. If you’re not caught up, now’s the time to binge—and buckle up.
3. Gachiakuta – The Wildest Newcomer of the Year
New kid on the block Gachiakuta is already making waves before its first episode even airs. Based on the gritty, graffiti-inspired manga by Kei Urana and supervised by Fire Force’s Atsushi Ōkubo, Gachiakuta tells the story of Rudo, a young outcast cast into a junk-filled abyss where criminals are abandoned to die.
But instead of perishing, Rudo finds power in the trash around him and joins a revolutionary group known as the “Janitors.” Expect slick animation, punk energy, and social commentary wrapped in explosive action. This one’s for fans of Dorohedoro, Chainsaw Man, and anything with wild world-building and grime.
4. Sakamoto Days Part 2 – The Silent Assassin Speaks Again
Everyone’s favorite chubby hitman is back for more gun-fu comedy and heartwarming chaos. Sakamoto Days Part 2 picks up right where it left off—Sakamoto’s peaceful convenience store life keeps getting interrupted by enemies from his assassin past. But unlike other action anime, Sakamoto Days keeps the violence creative and the humor sharp.
Studio TMS Entertainment seems to be pulling out all the stops this season, with crisper animation and bigger fights teased in the previews. Whether it’s absurd stealth missions or heartfelt dad moments, this series is a perfect watch for fans of Spy x Family, City Hunter, or John Wick… if John Wick ran a mini-mart.
5. Dr. Stone: Science Future Part 2 – The Final Invention?
Dr. Stone continues its intellectual sprint into the future with Science Future Part 2. Senku and his science crew are on the verge of discovering the truth behind the global petrification event, and that means exploring the most distant corners of the Earth—and beyond.
This arc promises not just new gadgets and breakthroughs, but an emotional climax that could change everything we thought we knew about the series. If you’re a longtime Dr. Stone fan, this is the moment it’s all been building toward. And if you’re new? Go back and start Season 1. Trust us—it’s worth every second.
