Dear CEOs,
This is Kim Hyun Soo, the Head PD of CounterSide.
We thank all our CEOs for all the support and love sent to CounterSide.
In this month's Dev Notes, we'll provide more details about the upcoming updates during June.
[ Mainstream EP. 13 - The Law of Creating a World Part 2]
The first news we’d like to share with our CEOs is that Mainstream EP. 13 – The Law of Creating a World Part 2, the follow-up to Part 1 (updated on Wednesday, May 20th (UTC-5)), is scheduled to be released on June 24th (UTC-5).
Like Part 1, this upcoming Part 2 has been prepared with a rich and expansive story, going beyond the scope of our previous Substreams—and will mark the grand conclusion of the Mainstream storyline.
Part 2 will continue directly from where Mainstream EP. 13 Part 1 left off, covering the latter half of the episode.
We won’t be sharing specific plot details in this developer note as we believe it is more enjoyable to experience the story firsthand. We kindly ask for your understanding on this matter.
We also sincerely apologize for the extended gap between the updates of Part 1 and Part 2, which differs from the typical schedule of previous Mainstream and Substream episodes.
We’ve taken this time to ensure the story is crafted with the highest quality, and we sincerely hope our CEOs will look forward to what’s to come.
[ New Persona Employee - ???]
In June, a new Persona employee will be joining the roster.
This employee will make her debut in Mainstream EP. 13 – The Law of Creating a World Part 2, appearing in a brand-new look. To ensure that our CEOs can fully enjoy the story without spoilers, we will not be revealing the identity in this developer note or the monthly preview. We appreciate your understanding.
The new Persona employee is a 3-cost Soldier-type unit, currently designed as a Striker who deals increased damage to Ranger opponents.
Please note that this new Persona employee will be available through Normal Recruitment.
We hope you're looking forward to seeing who this will be and how she will leave her impression.

[ New Operator - ??? ]
Next, we’d like to introduce a new Operator coming this June.
This Operator is a key figure connected to the Zodiac Knights, and she will play a pivotal role in the storyline to be revealed in the future.
With her arrival, a new chapter unfolds—linking the past and present. We hope you look forward to discovering what stories await, and what consequences her choices may bring to the Knights.
Unlike existing Operators who primarily support allies with buffs or weaken enemies with debuffs, this new Operator is being designed to take part in combat in a more special and impactful way—applying debuffs to enemies while also temporarily summoning units that can deal powerful damage.
We’re excited to see how this new form of Command Skill will shape battles, and once again, we invite our CEOs to look forward to the unfolding story and the effects her decisions may have on the Zodiac Knights.

[ Regarding Invincibility Effect ]
In CounterSide, there are various forms of invincibility effects, such as Immune to DMG possessed by certain employees, or invincibility during Ultimate Skill animations for others.
However, since the timing and duration of these effects vary depending on the employee, we understand that it may be difficult for our CEOs to clearly grasp how each invincibility effect functions.
To improve clarity and help our CEOs better understand and utilize these effects in battle, the development team will be redefining the invincibility effects as outlined below:
■ Immune to DMG with Visual Effects
※ Updated on May 30, 2025 at 05:25 (UTC-5)- When Immune to DMG is triggered while under a non-damaging Stun or Sleep effect, the Stun/Sleep effect will be removed, while Immune to DMG remains active.
- When a non-damaging Stun or Sleep effect is applied to a unit already under Immune to DMG, the unit will stagger, and the Stun/Sleep effect will be removed, while Immune to DMG remains active.
* Other status effects such as Freeze, Bind, and Confusion will not be removed.
* Under Immune to DMG, employees cannot be hit by enemy attacks, so status effects that involve damage will not be applied.
* If Immune to DMG is triggered during a damaging Stun or Sleep effect, that effect will be removed. (This behavior remains unchanged.)
* This clarification of the Immune to DMG policy applies only to non-damaging Stun or Sleep effects, such as those caused by Command Skills like Asha or Chloe Starseeker. It does not apply to effects inflicted through attacks.
■ Immune to damage State (No Visual Effect)
Grants complete immunity to all types of damage and status effects (including those labeled as "cannot be canceled").
Unless otherwise noted, this state is applied for a certain duration during Ultimate Skill activation.
We hope this updated approach to invincibility effects helps CEOs utilize these mechanics more effectively in battle.
[ Unit Tag System Expansion ]
To make it easier for our CEOs to find and organize employees by specific tags, we are planning to expand the current unit tag system used in the Form Squad and Collection menus.
With this expansion, we will be adding more detailed tags based on each employee’s skill effects, allowing for a clearer understanding of their unique characteristics.
※ Examples
Judy Swift: Chill, Sure Fire
Breakbeat Alex: Barrier, Nullify Buff, Stun, Incoming Healing -
* Please note that tag names may change upon the actual update.
We hope this expanded unit tag system helps our CEOs easily find the employees that best match their strategies and preferences.
This concludes the brief overview of the June update.
Thank you for supporting us.
