"Looking back, it’s been nearly 10 years since I started working on 2.5D stage plays. And now, here I am working on the music for Oshi no Ko 2.5D Stage Play Arc... Can such things really happen!? There’s a bit of fear like opening Pandora’s box, along with self-reflection. But setting those worries aside, I’m eager to deliver 2.5D music from the frontlines, in a bold and unique way that only Oshi no Ko can offer!"
