MATADOR

It's called a trill, but it's very long and quite fast at 168 bpm, so it feels like a pretty difficult chart. It might be easy if you're confident in your stamina or good at trills..?

It shouldn't be in the mid-low tier, right..?

It's easy as long as your gauge doesn't drop, even if you miss some notes during the drill.
