When I use an innerware ticket "Duskwake Regalia [In]",
"Behind the Dusk [In]" is registered as a usable innerware.
This can be very confusing, the name differs from the scratch prize list or the official announcement (https://pso2.com/news/announcements/crimsondawn).
A related thread is here (https://forum.pso2.com/topic/2268/behind-the-dusk-shadow-in/).
Also, there is a similar case "Kabuki Thunderstroke [In]" and "Kabuki Kamitoki [In]".
