The special site announced that applications would be limited to one per fan club. If an applicant submitted multiple applications for the same event and same preference, the additional applications would be invalidated.
However, Rakuten Ticket informed us that they interpreted "one application per fan club" to mean that if multiple fan clubs submitted applications, only one would be valid, and the rest would be invalidated.
This differed from our intended implementation, so we confirmed the issue with SME Inc., which manages the event jointly with us.

Concerns arose that SMS verification and Rakuten Ticket’s handling of multiple fan club applications might cause unexpected issues.
Rakuten Ticket was asked to review its system, and discussions confirmed that a customer with multiple fan club memberships should be eligible to apply through each membership separately.
We agreed with Rakuten Ticket that this would be handled as an independent issue and not linked to the fan club system.

Rakuten Ticket customer support received inquiries from customers who had their applications invalidated despite applying through different fan clubs.
Rakuten Ticket responded that "if a customer joins multiple fan clubs with one ANYCOLOR ID, they can apply separately for each fan club."

We received multiple inquiries questioning whether applications were invalidated due to membership in multiple fan clubs.
We raised concerns that the lottery process might have been unfairly affected.
We contacted Rakuten Ticket to reconfirm the issue.

A growing number of inquiries reached us regarding the issue, and discussions surfaced on social media.
We summarized the concerns and contacted Rakuten Ticket for a direct response.

Rakuten Ticket responded that multiple fan club applications were counted as a single application.
However, due to continued discrepancies with customer reports, we asked Rakuten Ticket to re-investigate the number of invalidated entries.

Rakuten Ticket reported to us that their earlier response contained inaccuracies.
They confirmed that applicants who applied through multiple fan clubs had their lottery entries invalidated inappropriately.

We began considering compensation for affected customers and reviewing the appropriate apology measures.

Rakuten Ticket informed us that a miscalculation had also affected ticket sales for "Ichigo Yomi 1st LIVE: My Fair Lady," resulting in fewer available tickets than intended.
We prepared an official statement on additional sales.

We confirmed that some affected customers still had not had their invalidated applications resolved.
Given the approaching date of "Ichigo Yomi 1st LIVE: My Fair Lady," we decided to issue an official apology and offer additional ticket sales.

We continued accepting reports from affected customers.

We compiled our response and formally announced the incident.
