Sword Art Online theme and insert songs (1–10)
Separate WaysHaruka Tomatsu

An insert song from Season 5, Mother’s Rosario arc, episode 24.
As expressed by the opening phrase, “We really took the long way around, didn’t we?”, it’s a gentle piece from Asuna’s perspective, portraying her resolve to cherish the days she spent with Yuuki and to live through many seasons without forgetting them.
Sword & SoulKirito

A song that expresses the world of the anime Sword Art Online through music.
The protagonist Kirito’s strong conviction and sense of justice resonate in the heart alongside a powerful melody.
The lyrics, which capture each moment and sing of the courage to find hope even in despair, are sure to encourage those facing hardship.
Created as a character song, it’s especially popular among anime fans.
With voice actor Yoshitsugu Matsuoka singing Kirito’s feelings, combined with a V-rock-leaning sound, it will undoubtedly leave a deep impression on listeners.
If you listen after watching the anime, Kirito’s determination will come through even more clearly.
Relife BulletSinon

Sinon’s character song from Season 3, the Phantom Bullet arc.
As reflected in the opening and ending themes, this song likewise captures her feelings of loneliness, inner conflict, and heartfelt gratitude toward Kirito, who pulled her out of the darkness.
It’s a wonderful track filled with those emotions.

courage(OP)Haruka Tomatsu

The opening theme for Season 4’s Calibur arc (episodes 15–17) and Season 5’s Mother’s Rosario arc (episodes 18–23).
While the setting differs between the Calibur arc and the Mother’s Rosario arc, the song primarily portrays the latter.
It beautifully captures, through its tone and melody, the feelings of Asuna and Yuuki—the strongest female swordsman known as the “Absolute Sword,” who bears a heartbreaking past and future.
It is one of the finest tracks in SAO.
Lovely Super Idolsilica

This song is packed with Silica’s cuteness.
It’s a lively, bright track about yearning to be an idol and the desire to shine.
Released in August 2014, it’s included in the Sword Art Online Song Collection.
Set to a poppy, catchy tune, it sings about shining on stage and expressing gratitude to someone special.
It’s also very popular as an anime character song, fully showcasing Silica’s charm.
Recommended for times when you want to boost your spirits with friends or cheer yourself on.
Liberty RosarioYuki

Yuki’s character song from Season 5’s Mather’s Rosario arc.
In the story, she often shows a somewhat fragile expression from the very beginning, but in this track her tomboyish, childlike charm and her caring feelings toward the guild members and Asuna are expressed in a pop, classic-anime-song style.
It’s a great song that lets you glimpse the parts of her heart that aren’t just sadness.
Sky The GraffitiLeafa

Leafa’s character song, the heroine of the Season 2 Fairy Dance arc.
She has the shocking backstory of being Kirito’s sister, Suguha.
With a strong sense of justice and a competitive spirit much like her brother’s, plus her thoughtfulness toward others, the song is filled with her straightforward, earnest feelings.
