Yeah ... I was in a hurry. The Raditz assault has been renewed this time, but after clearing EX6 in HARD mode, "BONUS BATTLE" with the notation "One more time today" will appear.
The reward is EX Raditz's Awakening Z Power. The update is at 15:XNUMX noon, so if you don't clear it by then, you may miss today's awakening Z power.
