Mitsunotsuki -For The Film-

A song chosen as the theme for the film Let Me Eat Your Pancreas, starring Takumi Kitamura—member of the dance-rock band DISH//, known for their hit Neko—and actress Mei Nagano.

Never Ending World

This song, “Never Ending World,” was written in response to the Great East Japan Earthquake and is included on the triple A-side single “INORI,” released in 2011.

Mermaid RhapsodySEKAI NO OWARI46rank/position

SEKAI NO OWARI Mermaid Rhapsody

A popular group, SEKAI NO OWARI, delivers a sparkling song that evokes the summer sea and the freshness of budding love—perfect for listening to in summer.

This track is also the theme song for the film Princess Jellyfish.

In the fairy tale, the mermaid falls in love with a prince, but because she isn’t human, she can’t love like an ordinary girl.

While the fairy tale is a sad story, the mermaid in this song thinks that even if she can’t go to meet the one she loves, it’s not so bad to stay where she is, because that special someone will come to her.

It’s such an adorable song, isn’t it?

RAIN (Acoustic ver)SEKAI NO OWARI47rank/position

It uses an acoustic version of the song “RAIN,” whose gentle tone enhances the world of the ad.

One can only wish a jukebox like this really existed.

FantasySEKAI NO OWARI48rank/position

The End of the World/Fantasy

Released in November 2010 alongside “Angels and Demons” as SEKAI NO OWARI’s second indie single, “Fantasy” is said to be a song that vocalist Fukase wrote when he was a first-year high school student.

With its cheerful, upbeat feel, the song is notable for having a relatively narrow melodic range, making it one of the easier SEKAI NO OWARI tracks to try singing.

The lyrics, perfect for cheering someone on or giving yourself courage, are also a highlight!

Death MagicSEKAI NO OWARI49rank/position

Death Magic

SEKAI NO OWARI’s early masterpiece “Death’s Magic.” Like “Phantom Life,” it features subtly serious lyrics paired with a euphoric track and vocal lines.

This piece stays within a narrow vocal range throughout, so even those who can’t hit high notes should be able to sing it without trouble.

However, because of that, the impact of the chorus is somewhat weaker, so to sing it well you’ll need to add clear articulation to your pronunciation.

In particular, make sure to start the chorus with crisp enunciation and projection.
