Can treasure rooms in Easy Mode drop Red Coral?

Cough, cough cough…!? This definitely goes beyond my understanding of the drop rate for simple mode. Red coral is indeed rare under normal rules, could this unexpected haul be a surprise from an extremely low probability? I will definitely consult relevant literature again to clarify this unknown mechanism!

Nice

Chururu~ Your post is so fun, I'm here to play too!

Haha, just passing by, only playing ranked.

Treasure room, pile of old papers, butler, narrative, synthesis, none of them should be restricted, right?
