Overfly (Sword Art Online ED2)

There is a softness to how this song opens — a gentle piano figure and acoustic guitar threading together before the full arrangement blooms. Haruna Luna's voice arrives like morning light through a window, warm and slightly breathy, with a naturally girlish register that never tips into affectation. The production is lush but restrained, leaning on sweeping strings and a mid-tempo pulse that feels both wistful and forward-moving. What makes the song emotionally complex is how it holds grief and determination in the same breath — the lyrics circle around the idea of rising above loss, of becoming something that transcends pain, without ever feeling triumphant in a blunt way. It is yearning made beautiful. The chorus lifts with a swell that mirrors the feeling of clearing a difficult height, the kind of emotional catharsis that comes not from victory but from endurance. As the second ending theme for Sword Art Online, it arrived in a moment when the series had deepened in emotional stakes, and the song carries that weight — it speaks to survival, to love that persists through separation. This is a song for late evenings, for the quiet after something difficult has passed, for the particular kind of peace that only arrives after sustained struggle. Luna's delivery is sincere without overselling any single moment, which is what keeps the song from becoming saccharine.
