There will be a new event type starting on 9/8 11 JST called Asari-sensei's Producing Seminar.

This appears to take a similar form to Kunio's Producingbowl in which event producing for certain idols will be active to produce memories from. Instead of score ranking, the event item of Asari Stickers can be used to reroll memory abilities.

This time around, the event mode type to use is Anomaly. However, skill cards from different plans will appear, in this case Sense cards. That's right, you will produce Anomaly idols with Sense cards.
