Secret Connection 2 was added to her website on November 24, 2020, with the same purchase widget. 1000 JPY.
Secret Xtra was announced and will be sold at TGMS2021. A GBA-style 2-track CD with bonus MIDI source data on the disc. Sounds like she wasn't sure if TGMS was going to happen this year, thus the relatively light mini-album.

Already on the site, didn't see it)
