>>44097771I still have my 3DS and Ultra Sun, so I have access to just about every event through Pkhex, as long as the wonder card file or Pokémon data file has been dumped. I do have this event.
>>44097648There's no mistake here. An English language file can receive Japanese serial and Wi-Fi events if the cartridge is Japanese, and NA/PAL cartridges can receive local Japanese events. The event Pokémon can have an English name if received by a game set to the English language as long as said game can communicate with the event server.
