The production features newly composed solo songs for all 28 idols belonging to 283 Production, performed by their voice actresses in character costumes, with a mix of individual numbers, unit pieces, and theatrical or dramatic segments that highlight each idol’s personality.Because today is Day 1, fans attending in person or watching the stream are posting impressions of the opening, specific performances, new songs, staging, and overall atmosphere. Related after-concert gatherings have also been organized nearby, adding to the volume of posts. The combination of a long-awaited format, brand-new material, and the live happening right now is what made the tag trend.
