Anyways they have a new song for Asahi Clear.
Said this before and I'll say it again. the frustration here is if you add up all the side work and one off singles Ami and Yumi have done since "Thank You," they could handily spin up an album. Some of this may be entirely out of their control, depends on who owns all the music as they shifted labels (they do remain represented by SMA which can be confusing) and commercials might introduce other complexities.
While it looks like 2020 has a lot on the calendar for Puffy, they have talked about ending their run this year so it will be curious to see if they hold to that or that was idle speculation their part. My take is it seems like they do just enough to keep going.
Also a side note, I think they are a dark horse for the 2020 Tokyo Opening Ceremonies given they are one of a handful of Japanese acts to have a significant international following.
