This dreamy song likens the unique wistfulness and fragility of summer to a moon floating over the sea and drifting jellyfish.

Chosen as the opening theme for Season 4 of the TV anime “Rent-A-Girlfriend,” it will be released as a single in August 2025.

The lyrics were written after the members repeatedly read the original manga, crafting them to closely reflect the protagonist’s wavering feelings of love.

The frustration of not being able to be honest about your emotions and the aching longing for someone you care about perfectly mirror Kazuya Kinoshita’s state of mind.

If you’re struggling with your feelings for someone you like, listening to this track will surely give you the courage to face your own heart.

Light Heading Toward YouAkino Arai

Light Heading Toward You

This is the opening theme of the hidden gem Zegapain, where an “endless summer vacation” continues.

In the real world, the protagonists struggle to survive as humanity faces a crisis in a devastated space environment.

I felt the theme perfectly matches the idea of transferring memories to a server and spending a utopian summer school life in a virtual world.

At the time, there were extremely few anime openings with an electronica or ambient touch, making it quite unconventional.

It’s a delicate, beautiful song that showcases Akino Arai’s unique artistry.

Super☆Affection [Sūpā ☆ Afekushon] (Carnival Phantasm OP) Full Version (Video: CP + Fate/Zero)

This is the opening theme for Carnival Phantasm, an original animation video produced as TYPE-MOON’s 10th anniversary animation.

TYPE-MOON continues to create hugely popular works in anime and games.

As a festival-style crossover that brings together series like Fate and Tsukihime, the song has an upbeat, high-energy feel that’s perfect for summer.

DreamsHIGH and MIGHTY COLOR

DREAMS – HIGH and MIGHTY COLOR

A single released in 2007 that served as the ending theme for DARKER THAN BLACK.

It’s the group’s first duet song featuring Yusuke, who had previously focused on rap and chorus, and vocalist Maki.

The lyrics, which depict the emotions of the characters in the story, convey a sense of poignancy.

Hyadain's Kakakata☆Kataomoi-CHyadain

The opening theme of Nichijou, a popular gag manga adapted into an anime.

Contrary to the title, it’s a gag anime where seemingly absurd developments unfold that make you think, “Does something like this really happen in everyday life?” This song perfectly weaves that worldview into its lyrics.

Its high-energy, up-tempo progression exudes the zany vibe of a gag anime.

Brimming with a sense of speed, it delivers a refreshing feeling reminiscent of the breeziness of summer.

Katsushika RhapsodyKohei Dojima

KochiKame Two Major Opening Theme Medley

It’s the opening theme song of the anime “Kochira Katsushika-ku Kameari Kōen-mae Hashutsujo.” Unlike the intense main episodes of “KochiKame,” the video leaves a strong impression with its leisurely depictions of scenes from Katsushika.

Even people who have never seen the real Katsushika can feel a certain nostalgia, and through the protagonist Ryō-san, you can savor the atmosphere of a Shōwa-era town.

Yuzu “Muscat” Music Video

Kids love it! The anime Crayon Shin-chan—whose movie version is known for moving even adults—had its 16th opening theme handled by Yuzu.

Muscat is a brisk, refreshing track, complete with handclaps that lift your spirits just by listening.

It’s a staple summer anime song and a go-to dance number for children at events like sports days and school performances.
