Leaked information from reliable leaker Leifa has provided insights into the huge changes coming to Zenless Zone Zero's Decibel and Ultimate mechanics in Patch 1.4. These updates are set to reshape how players approach battles, making ultimate strategy more free and less restricted.
One of the main changes is that all characters will now have separate Decibel Meters, generating different amounts of Decibels for themselves and their teammates. This adds a new layer of combat to ultimate usage as well as increase the strength of some older characters who were never able to use their ultimate due to your DPS character always using it. Additionally, when a character's ultimate is ready, a small icon will now appear next to their Energy Meter, providing a clearer visual cue for players.

One such example is defense agent Seth Lowell who will be able to utilise his Ultimate: Justice Prevails to generate more Resolve. Another huge example is Burnice White in Jane Doe teams where both Burnice and Jane are fighting for Ultimate useage.


Some of the above information from Leifa was known already through other leaks and developer information however, the beta for 1.4 has confirmed there will be no cooldowns on using Ultimates, and there won't be any changes to the Decibel cost for activating them. 

As a result, characters are also starting to gain mechanics which can influence their own Decibel generation. It is also theorized by players that the current lack of Decibel generation in Harumasa's kit in the initial beta is this way while the developers fine-tune these changes.
This is overall a great change that players have been highly anticipating and will bring exciting changes to the combat in patch 1.4.

Asaba Harumasa is a new Electric Attack character releasing in patch 1.4 for Zenless Zone Zero, however it seems he is currently unfinished?
While the patch 1.4 beta has arrived, it seems Harumasa has not. Dataminers initial looks into things reveal that currently in the beta, he is still very unfinished. Reliable leaker Leifa has mentioned that he is still missing animations and even Decibel generation while there is less kit information too as a result. 
Fans of Asaba Harumasa should not be concerned however, with the changes coming to Decibel generation in patch 1.4 it likely means that the developers are spending the much-needed time to ensure he is properly balanced around this new system. This new system giving each character their own Decibel Meter and their own generation is a highly anticipated change to the game after player feedback around not being able to use the ultimates of many characters.

What information we do currently have, comes from the telegram channel NewEriduStand:
 

Hoshimi Miyabi is a new Physical Defense character releasing in patch 1.4 for Zenless Zone Zero, read about her preliminary beta kit and leak information.
Miyabi is currently a very anticipated character for Proxies, with her unique drip marketing showing an unknown element causing many discussions to occur about her role in the game. 
Placeholder for tweet 1854736895877452179 These leaks offer a glimpse into Miyabi's abilities and how she might shape the dynamics of the game. As with all information surrounding leaks, everything is entirely subject to change. 
The information below is also simply a translation from the CN beta so expect the occasional TL issue, but most importantly, characters often go through several changes during a beta which can drastically change how she is played. The information for this is provided by reliable leaker Leifa. 
Leifa has also been kind enough to create a detailed spreadsheet showcasing this information more clearly and in a lot more detail than previous patch leaks and should also last if the thread goes down.
