ClariS’s debut single “irony” became a work that stayed in many people’s hearts.

Gaining popularity through its tie-in with the anime “Ore no Imouto ga Konna ni Kawaii Wake ga Nai” (Oreimo), the song’s lyrics, which express the feelings of teenage girls, resonated with a wide audience.

Since its release in October 2010, it has maintained a high position on the Oricon charts.

The transparent, pure vocals of the two members of ClariS are particularly memorable.

It’s a track we especially recommend to anyone who’s struggling to be honest with their feelings.

Released in November 2006, this song served as the opening theme for the anime Pokémon Diamond & Pearl and was beloved by fans for an impressive 94 episodes.

This is the 15th single by female singer LiSA, used as the theme song for the TV anime Demon Slayer: Kimetsu no Yaiba.

The song’s structure is designed to maximize the impact of the chorus by creating strong dynamics—contrasting the intense rock sound of the A section and chorus with a quieter B section.

In the chorus, simple chord progressions are interspersed with occasional diminished chords, striking a balance between accessibility and a memorable hook.

On the Oricon charts, it achieved both the “last No.

1 of the Heisei era” and the “first No.

1 of the Reiwa era,” setting records that transcend the typical scope of anime songs.

This song, created as the opening theme for Season 2 of the TV anime Dandadan, was written and composed by Aina the End.

It will be released digitally in July 2025, followed by physical releases in two formats—CD and Blu-ray—in September.

Its exhilarating sound layers with a mysterious melody, conveying the protagonists’ determination to fight to protect what’s precious to them in a straightforward way.

As Aina herself says, she “reduced the distortion in her voice and sang straightforwardly,” resulting in a clear and powerful vocal performance.

It perfectly matches the anime’s worldview, where the occult and youth intersect.

It’s a track we recommend when you want to keep moving forward or need a push on your back.

It’s an energetic piece that makes you feel empowered just by listening.

Released as a single in February 2010, the song became the opening theme for the anime “Pokémon Diamond & Pearl” starting with episode 158.
