Following the issue confirmed with the Vanguard Swap character "Byakko," which was recently patched, our team conducted an investigation into similar skill behaviors and identified similar issues among the characters above.
We deeply apologize for causing continued inconvenience to our players due to similar issues occurring in succession.
This issue has been present since the initial implementation of these characters.
While we will proceed with utmost caution regarding potential fixes, as this behavior differs from our original design intent, please be aware that we may standardly disable (fix) all invulnerability-bypassing effects in a future update. We kindly ask for your understanding in advance.
Furthermore, dealing damage to invulnerable enemies due to this issue will not be considered an "exploit," and no disciplinary measures or penalties will be applied to player accounts for doing so.
Once again, we sincerely apologize for any inconvenience this may cause to everyone.

Greetings from the Onigiri Service Team.
The details of the 9/3/2026 JST update are as follows:

In the second half, Oda Nobunaga - Thunderbolt and Okada izo will appear!

Please see 
During the event period, the warding dungeon [Assault! Cursect Princess -Puragtorium-] will be available.
Purgatorium dungeons appear irregularly, but you can get the exclusive Purgatorium Treasure items!
■Concerning Purgatorium Dungeons
・The monsters have high resistances, and attacks other than super effective attacks will be less effective.
Additionally, these monsters will have extra strong attacks.
The Cursect Princess also has a Special Resistance Acquisition that increases her
resistances based on the attribute of the attack received. These values will gradually return to normal.
・Clear the dungeon with a B Rank or higher to be awarded Purgatorium Treasures.
・Occasionally when clearing at the highest difficulty, you can get a rare Magatama!

The Vanguard Swap character Byakko can be unlocked by using the item Summoning Scroll - Byakko -.
In addition to following you around and fighting alongside you, you can take control of Byakko by performing a Vanguard Swap.
Byakko is a Dual Sword-wielding character who primarily uses Mountain and Wind element attacks, and features the new Laceration Gauge system.
When you Vanguard Swap to Byakko, the Laceration Gauge will appear in the bottom-right corner of the screen.
Laceration accumulates separately for each monster. Performing either of the following actions will display the target monster’s accumulated Laceration and its name on the gauge.
・Aim the reticle at the target
・Lock on to the target
※Monsters without a nameplate will not display a name.
※The gauge will disappear if 10 seconds pass after the reticle or lock-on is moved away from the target.
The Laceration Gauge can display a maximum value of 999, but Laceration can continue to accumulate beyond 999.
The gauge will reset if 1 minute passes after its value increases or decreases.
■How to Accumulate Laceration
Laceration accumulates by hitting enemies with normal skills.
For certain skills, hitting an enemy from the optimal distance will increase the amount of Laceration accumulated.
When you are at the optimal distance from an enemy, the lock-on marker will enter the Full Lock-On state.
Normally, Full Lock-On is displayed whenever the target is within the optimal range of the selected skill. However, some of Byakko’s skills will fall outside their optimal range if you are too close to the target.
Additionally, certain skills will behave differently when activated from the optimal distance, increasing their number of hits.
■Laceration Gauge
Ougi skills will be enhanced by consuming Laceration when the targeted enemy has accumulated at least a certain amount of Laceration. Enhanced Ougi skills will have an increased number of hits and greater power.
The amount of Laceration consumed varies depending on the Ougi skill.
■Ougi Ivory Fang Clawfeast Frenzy
Unleashes a furious barrage of attacks upon enemies directly ahead.
■Ivory Fang Tiger Roar Rally
Inspires allies with the majesty of the God of War.
■Buff Effects
・Damage Cap +10,000,000
・Attack Power +15%
・Movement Speed +15
・Attack Speed +15
・Grants self 2 stacks of Guts (Recovers 10,000 HP once upon receiving fatal damage)
・Grants nearby party members 1 stack of Guts (Recovers 10,000 HP once upon receiving fatal damage)
【Addendum 8/20】
