New ReLive official art in 2026 is quite insane I wish this wasn't heavily compressed tho
Anyway as the copyright name suggests it was part of the expo to celebrate the 9th anniversary of the franchise that took place recently

The ReLive section had never seen before concept arts of the cast and discarded content due to the EoS (every birthday art was already done, and Elle had one too!) (I feel like they had some plans for her after the end of Arcana Arcadia, she's also holding hands with Aruru in this art due to being a new Frontier school member)
Someone wrote everything new they saw if anyone is interested, photos were not allowed tho...
Hopefully they'll make all the concepts from the expo public, which I guess it's something they'll do according to a reply in the same post.
