Koi-kurenai (濃紅) (4/6/7/10; 950 notes on Oni)
The final song of the Taiko no Tatsujin x INSPION collaboration has just hit the public arcade scene! While bearing the least amount of notes of the newly-introduced song trilogy, Koi-kurenai's Oni mode surely shows its claws in form of yet another relentless stamina-draining experience with broken-down cluster formations mostly made of short-lasting repeated bursts, not that much dissimilar to former Oni trials like the one of G Ishiki Kajou.
