15 Anime Summer 2025: Biggest Sequel Hype Trains

This one has a generic, cliché plot: misunderstood scary guy meets shy girl. But I promise you’ll melt while watching them, it’s pure sugar overload.

Rintarou Tsumugi looks like a scary delinquent, but beneath the tough exterior he’s a softhearted guy helping at his family’s pastry shop.

That’s where he meets Kaoruko Waguri, a bright, cheerful girl who doesn’t judge him by appearances.

She treats him like a person, and that simple kindness starts to grow into something deeper.

This one is perfect if you love romance with a touch of elegance. The story explores how love blooms between characters from different social circles, with plenty of heart-melting, emotional moments.

There’s little to no drama between the MC and FMC. Instead, they’re just two people who admire each other and genuinely enjoy spending time together.

If you’re into romance that takes this sweeter, more relaxed approach, this anime is a delightful watch. Oh, also no unnecessary fanservice so far.

Dan Da Dan exploded onto the scene with its wild blend of psychic battles, alien invasions, cursed spirits all tied together by a story that somehow makes it work.

It’s one of those rare shows that balances sheer ridiculousness with genuine emotional beats.

Science SARU’s animation was a perfect match for the show’s kinetic energy, and fans are expecting nothing less this time around.

After seven years of waiting, the dive club is back. And somehow, they’re even more unhinged than before.

Fans of Grand Blue’s chaotic, beer-fueled antics are finally getting the sequel they’ve been craving. If you’ve read the manga, you already know just how absurd things are about to get.

Season 2 will give us more diving club insanity, more shirtless chaos, and even a bit of love-related misunderstanding.

The legendary drinking gags, the extreme faces, the sheer “what did I just watch?” energy… season two is ready to top all of that.

It may be juvenile humor, but it’s done with so much heart that you can’t help but laugh along.

And beneath all the madness, there’s a surprising amount of wholesome friendship that makes you the cast even more.

So… should we call this Season 2, or is it technically Season 5 now?

Now for one of the most anticipated new entries, Gachiakuta!

This dark fantasy manga has been generating massive hype, and its anime adaptation is shaping up to be one of the season’s biggest wild cards.

The story follows Rudo, a boy cast into an abyssal junkyard for a crime he didn’t commit. Instead of death, he discovers a nightmarish world crawling with trash-born monsters.

The animation style and killer aesthetic give it strong Fire Force and Jujutsu Kaisen vibes. And with Studio Bones (My Hero Academia) handling the adaptation, you can expect fluid animation and a moody, immersive world.

This might be one of the creepiest and most hauntingly emotional series this season.

At first, it looks like a heartfelt tale of friendship, but then it twists into unsettling horror when one of the main characters is replaced by something not quite human.

This isn’t your typical BL story. It’s a chilling psychological drama about loss, identity, and the horror of something wearing your best friend’s skin.

Renowned for its eerie atmosphere and complex character study, the manga has built a reputation for leaving readers unsettled long after they finish reading it.

The adaption captures that same energy, making it one of the most hauntingly beautiful and thought-provoking highlights of the season.

Hey look, it’s Bocchi… but in a fantasy world.

Secrets of the Silent Witch follows Monica Everett, the youngest member of the Seven Sages, who is secretly tasked with protecting a prince at an elite academy.

Though a magical genius, Monica is so shy that she hides her power, even going as far as developing silent casting to avoid drawing attention.

Watching her juggle the pressures of being a protector while battling her social anxiety gives the story both charm and relatability.

It’s the classic “overpowered but socially anxious” setup, executed with heart and humor.

You get a bocchi-type heroine who’s secretly a badass, a sprinkle of romance, and the classic blend of school life wrapped in a fantasy setting.

The stylish, nocturnal world of vampires returns in Season 2 of Call of the Night.

But this series isn’t just about bloodsuckers, it’s about the allure of freedom, loneliness, and connection that only the night can bring.

Season 1 gave us a mix of supernatural romance and late-night wanderlust. Now, Season 2 looks ready to deepen both the vampire politics and the tender relationship between Kou and Nazuna.

This series takes the familiar “new guy living with eccentric sisters” setup and adds something rare: genuine heart.

The Mikadono sisters are basically school royalty. One is a shogi prodigy, one dominates in karate, and one owns the stage in theater, but their talent has driven them apart.

Enter Yuu Ayase, a boy with zero special skills but one important promise to keep: fulfilling his late mother’s wish to create a true family.

What follows isn’t just comedy and awkward cohabitation (though there’s plenty of that).

It’s the story of Yuu slowly breaking down the sisters’ walls with nothing more than his awkward honesty and genuine kindness.

If your summer watchlist needs something easygoing and silly between all the intense action shows, this one is the perfect palate cleanser.
