RevSong hooks you right from the first chapter, pulling you along for the ride without even asking if you're ready. It's also easy to read without losing any substance.
It's hard to gush about it without spoilers, so I'll be brief.
RevSong hits two points I absolutely love web fiction for: everything feels meaningful, and everything is written from the heart.
I can't understate just how much I love Sayane's story. It's one of the most satisfying character journeys I've ever read, and easily my favorite in the isekai genre. Character development is done very well all around--even side character arcs are compelling.
And the songs... each one is crafted beautifully and I found myself imagining melodies and cadences for each of them, singing along in my mind. Songs I've only read are stuck in my head on repeat.
You won't regret giving Sayane your time and hearing the music again. But be careful, you won't want it to end.
