Zankyo SankaAimer
Aimer’s 20th single.
Released as a double A-side with “Asa ga Kuru,” it drew attention for being chosen as the opening theme for the TV anime Demon Slayer: Kimetsu no Yaiba – Entertainment District Arc.
Although the melody is fast with large leaps in pitch that might make it seem difficult, its driving momentum lets you power through it.
As the theme song of a hugely popular anime, it’s widely recognized and great for group singing, so don’t worry about the finer techniques—just have fun singing it.
aimlesslyAimer
This is Aimer’s 22nd single, released in 2023, and it was chosen as the ending theme for the anime Ranking of Kings: Treasure Chest of Courage.
While the song is a relatively simple ballad, Aimer uses an exceptionally diverse range of vocal expressions to beautifully convey the song’s world.
It may be a bit challenging if you’re aiming for a high score in karaoke, but the melody itself is very straightforward and beautiful.
Be sure to study in advance—such as the placement of rests in phrases, where to hold notes, and where to cut them off—and give it a try.

On nights when I’m too lonely to sleepAimer
The second single, “On Nights So Lonely I Can’t Sleep,” was released as a double A-side with “Re:pray” as a conceptual single.
The song, which secured multiple tie-ins including serving as the ending theme for the music program “MUJack,” is notable for its richly layered ensemble of piano and strings.
Its narrow vocal range and restrained delivery make it relatively easy to sing, but be careful with the leaps in pitch during the chorus—they can cause you to slip off the notes and make it hard to return to the original melody.
It’s a sentimental ballad number that you’ll want to sing while imagining the emotions conveyed by its heartrending lyrics.
bow knotAimer
The 11th single “Cho-Cho Musubi,” which drew attention for being written and produced by Yojiro Noda of RADWIMPS, was also used as the theme song for the information program Sukkiri!!.
The lyrics unfold a story that expands from the theme suggested by the title, leaving a strong impression.
While it’s a challenging song due to its high key and numerous melodic movements, the overall range isn’t that wide, so it becomes easier to sing if you adjust the key to suit your voice.
With its relaxed tempo, it’s a number where you can calmly follow the melody and still capture attention at karaoke.
STAND-ALONEAimer
It was released as a digital-only single by Aimer and was used as the main theme for Chapter 1 of the NTV Sunday drama “Your Turn to Kill.” The song has a melody that seems designed to bring out the full appeal of Aimer’s rich, powerful voice, and through her vocals and delivery, you can really feel her rock sensibility.
Now, if you’re going to sing this song at karaoke, the opening A-melody in particular might be a great place for lower-voiced women to showcase their strengths.
In the chorus there are some fairly high notes, and Aimer herself appears to blend mixed voice and falsetto to express them.
Even if you’re not confident with high notes, I hope you’ll practice and master this part.
Try to avoid tightening your throat; instead, open the back of your mouth in a rounded way, aim the sound toward your upper palate, and practice singing so the voice resonates fully within your oral cavity.
Believe Be:leaveAimer
The song “Believe Be:leave,” included on the 3rd album DAWN, was used as the ending theme for the music program ONCHIKA.
Its airy, transparent ensemble really lingers in the ears.
Although the key is a bit high, the restrained vocal delivery makes pitch control easier, and the melody has relatively gentle dynamics, so it should be manageable even for those who aren’t confident singers.
It’s a soft pop tune that will draw everyone in when sung at karaoke.
