Brass-driven idol rock with full anime-ending propulsion, CiON’s “渇望 (Katsubō) – Anime size ver.” is less a song and more a 90-second emotional detonation built for post-episode devastation. Your “sort of idol unit” description is dead-on, but what makes CiON uniquely addictive is that the brass and piano aren’t decorative—they’re the actual combustion engine, giving this single the feel of a live band anime anthem with theatrical punch and club-floor uplift.
The title translates to “Craving” or “Longing,” which perfectly matches the dramatic tension baked into the anime cut. The copyright trail confirms the tie-in is the ending theme for That Time I Got Reincarnated as a Slime (転生したらスライムだった件 / Tensura), making this one a huge crossover win for both anisong fans and your broader idol-rock readership.
