Nijisanji Collaboration Serial Code

Apparently, it's a ticket to draw from the collaboration event's Lucky Chance Gacha. It said there are a total of 5 in the game's guide. My target is the Tokineko plushie or the 5000 diamonds (supposedly) in the Lucky Treasure Chest✨️ Dream big! I'm allowed to dream until I pull! (I haven't posted the serial code itself)
