FFRK JP - Echoes of Happiness: part 1 (recruitable Shadowsmith)

An event that expands into the story left from the Record Dungeons, and Shadowsmith becomes a playable hero, it was about time.
More smaller parts are going to be released for the event to ensure I can record anything new. I am sorry I can't provide a translation from my own since I am not proficient in the original language, I'm making some sense from the dialogues with Google Lens and the japanese Record Dungeons as a reference but I am not able to get faithful to the localization work done in the Global version.
Original login background, soundtrack, and home screen are made to commemorate the event.
The event should take place after the confrontation with the Lich. Seems like the Shadowsmith is stuck again in the Record Dimension.
As a point to note gameplay-wise, the Historia Crystals have been buffed with Sorcery boosts, up to 5 99999 hits on the Ultra Historia Skill (from 4x9999 + 99999) and overflow damage on the Historia Skill (up to 99999).
