In the "EX Homerun Battle Z", which was added to the event "Yamcha's Homerun Derby" on July 2020, 7, you can collect the Zpower of Yamcha: Titans without restrictions. The Yamcha Titans you use will be one other than your own six, but you can increase the Z power gain by incorporating a bonus character in the six.
+9 when including new gacha characters. It will be +4 if you are the only super warrior that can be acquired at events.
Z-power has a chance to drop and is not guaranteed to be available. ×10 (+4) in the image will be a total of 6× including the normal drop ×4 and bonus amount ×10.
The opponent is kefra and the contents are the same as the daily home run battle. It will be cleared if you successfully complete the special arts twice. Be careful because you may use hitting arts and deadly arts.
It is best to avoid hitting arts at the burnishing step, and to be able to counter shots and tap shots with special arts. However, it seems that it can be cleared even if it does not become severe.
The other party is Kefra ...?
