To Mark the Day

In a fantastical world where music isn't just art — it's magic, Amiya's melodies are able to shift emotions, change the atmosphere around her, and influence the people who hear them. This music video, tied to the game Arknights, brings that concept to life in a single, concentrated burst of animation and sound. The song 'Kyou wo Shirushite' (voiced by Kurosawa Tomoyo) carries this quiet, bittersweet weight — Amiya channeling something deeply personal through her music, marking a day that matters to her. The animation leans into visualizing what that feels like, turning sound into color and movement in a way that's genuinely pretty to watch. It's short, just one episode, so you're not committing to anything. Think of it as a mood piece more than a narrative. If you liked the emotional punch of Your Lie in April or the way Nodame Cantabile made you feel something through performance scenes, this hits a similar nerve but wrapped in fantasy. The magic system where melodies literally reshape the world gives it a different texture than a straight music drama. It's closer to what Sound! Euphonium does with conveying emotion through instruments, except here the stakes are supernatural. It won't take much of your time, and if the song clicks with you, it lingers. Worth the few minutes.
