Difficulty: ☆9.5 (Only Extreme--no hard mode because I'm lazy)
Song producer: Hifumi (https://www.youtube.com/channel/UCHG5yLvj57pnMNm6perFrZA)

I actually don't really care much for this song, but it was short and had a high bpm, so I charted it anyway.
CSInput is included, but I tested and designed it with the keyboard in mind (i.e no single spams). Regardless, it's still perfectly playable on the DS4.
