We were asked on more than one occasion which episode we expected to be the "real" one.
We don't know how many if any more games will happen in the answer arcs, so we choose Legend as the most likely candidate from the question arcs.
Leads:
- The first tea party is a direct continuation of Legend, and every following interaction between Battler and Beatrice is framed as a continuation of that one. A discrepancy in the character description colors further supports this reading.
- Beatrice, Shannon and Kanon claim to have seen countless loops already, but this is merely the same magic fluff as the witch killing and reviving someone 100 times.
- It's not really a question you would ask unless you knew there is an answer.
