Hands down the best name of all songs in the game. It matches Kokoro well. Despite not showing facial expressions she sure puts passion in her actions
That build up was soooooo good like the original. Strings, violin, guitars, accordion. Everything making The Lost Emotion even better. I also get some Zinnia battle vibes from this
