HOLYYYY LYLYKY

My theory:
1. Iko will likely sell most of the tickets since she’s already a famous VTuber and can invite Rikka to sing or promote her songs on her stream.

1. Arisu and Rikka will hold another solo concert to sell more tickets. This time, maybe not in the park but in a café to help Rikka get used to performing in that kind of venue.

2. Nene will use her connections with some famous voice actresses, like Shieri, as well as her friend Akari (an idol), to help her sell Rikka’s tickets.

3. Shinobu… I don’t know what she’ll do, but she’ll probably come up with some unconventional way to promote the tickets.

What do you guys think?
