Before Taiko no Tatsujin starts its collab with Chain Chronicle on August 18, apparently they have to finish the matters with the last mobile RPG first.
Puzzle & Dragons come for another (and final?) round of collaboration with Taiko no Tatsujin Plus on Apple devices in this final week (August 10-16) before the ChainChron collab, once again opening Walking Through the Towers for free for a limited time, and reviving various draw prizes. The long-incomplete PazuDora Pack also completes with the 5th tune and one of PazuDora's newer boss fight BGM Fight the Fanatics (current pack owners may need to redownload to see).
