[New Content]

▶ New Agents

• S-Rank Agent Lucia (Support – Ether)

Okay, so I’ve been playing Lucia, and she’s a total support powerhouse! Basically, she can buff the whole team with Sheer Force, which seriously cranks up our damage output. During a fight, I can activate her Ether Veil: Wellspring ability, and everyone gets a huge HP boost – it’s a lifesaver! Plus, she can heal other Agents, which is awesome when things get dicey. She really keeps the squad going strong.

This Agent can be obtained through the “Wandering Night Lantern” Signal Search.

• S-Rank Agent Yidhari (Rupture – Ice)

Yidhari is a strong damage dealer who gets more powerful the lower her health gets. She can use charge attacks to both lose and regain health. When her attacks clash with enemy attacks, she can launch a follow-up attack that deals significant damage. If she has enough Decibels, she can use them to activate her Ether Veil: Wellspring ability.

This Agent can be obtained through the “Alone in a Shared Dream” Signal Search.

• A-Rank Agent Komano Manato (Rupture – Fire)

Komano Manato is a powerful damage-dealing Agent who uses Fire attacks. He’s not just about offense, though – he can also protect himself. Manato gains a ‘Blazing Heart’ through his abilities, which lets him enter ‘Molten Edge’ mode, significantly increasing his critical hit rate and unleashing devastating fire damage.

Starting with version 2.4, the A-Rank Agent Komano Manato (Rupture – Fire) will be consistently available in the “Star-Studded Cast” Stable Channel. Players using proxies can also try to find this Agent through Signal Search in Exclusive and W-Engine Channels.

▶ New W-Engines

• S-Rank W-Engine Dreamlit Hearth (Support)

Can be obtained through the “Dissonant Sonata” Signal Search.

• S-Rank W-Engine Kraken’s Cradle (Rupture)

Can be obtained through the “Dazzling Choir” Signal Search.

• A-Rank W-Engine Grill O’Wisp (Rupture)

Can be obtained through the “Dissonant Sonata” and “Vibrant Resonance” Signal Searches.

Starting with version 2.4, the A-Rank W-Engine Grill O’Wisp (Rupture) will be consistently available in the “Star-Studded Cast” Stable Channel. Players using proxies can also find this W-Engine by searching for signals in Exclusive and W-Engine Channels.

You unlock it as you progress through the main story, specifically Chapter 4 of Season 2, called “Memories of Dreams Bygone.” I’m excited to check it out!

Okay, so the latest update has added a bunch of new enemies, and I’m really excited about that! We’ve got the Wandering Hunter, Haytor, and then a whole crew of ‘Miasmic’ types – a Frenzied Maniac, a Trinox, a Shieldguard, and even a Cannoneer! It’s gonna make things way more challenging – and fun – out there.

A new challenge, Wandering Hunter, has been added to Notorious Hunt. Completing it rewards players with the Crimson Miasma Spike, an item used to enhance Core Skills. Players can also obtain this item by trading in the Hidden Treasure section of the Outpost Logistics supply exchange.

This update includes new environments and enemy types for both the Task Force Investigation and Battlefront Purge combat zones.

New Challenge stages have been added for Agents Lucia and Yidhari within the Perpetrator Battle – Task Force Assault mode. Yidhari’s stage will become available when her Agent Exclusive Channel is released.

Adjustments & Optimizations

▶ Systems

This update improves how Drive Disc upgrades are shown and filtered, and now includes suggestions for the best sub-stats to prioritize.

Improves how the red dot notification appears on screens like ‘Inter-Knot Missions’, ‘Mail’, ‘Profile’, ‘More Functions’, and throughout the app.

• Optimizes the auto-consumption logic for backup Ether Batteries.

Okay, so they’ve tweaked how time works in the game. Basically, every time I, as a player (or ‘Proxy’ as they call us), log in on a new day in real life, the in-game time jumps forward a set amount. It’s a simple way to make sure time keeps moving, and it automatically happens when I start playing each day.

• Optimizes the display and navigation logic for the Special Training Plan interface.

• Optimizes the score limit display for Bizarre Brigade.

• Optimizes Agent Vivian’s display in the Agent – Base and Agent – Skill interfaces.

This update rearranges how the Main Menu and other function screens are displayed to improve the user experience.

• Adjusts the presentation of some plot-related text.

▶ Others

• Optimizes some voicelines for English, Japanese, and Korean.

Issue Fixes

▶ Agents

Hey everyone, just wanted to let you know I’ve fixed a bug with Yuzuha! Sometimes, her special ability – the one that changes based on what ‘Flavor’ your enemy has – wasn’t working right when I was attacking enemies already affected by ‘Sweet Scare’. Basically, it wasn’t triggering when it should have. It’s all sorted now, so you should get the full effect when you’re battling!

This update resolves a problem that caused Agent Vivian’s umbrella animation to glitch in specific situations.

This update resolves a problem that caused Agent models to function incorrectly on some devices in specific situations.

This update resolves a problem where the camera would sometimes move strangely after Agent Alice used her charged Starshine Waltz attack.

This update resolves a bug that caused some Agents to unintentionally activate their Ultimate ability with unusual camera movements during a Bamboo Chain Attack.

This update resolves a visual glitch that sometimes happened after Agent Seed used their Chain Attack: Tempest of Frosty Petals.

This update resolves a visual glitch that sometimes happened when using the W-Engine Qingming Birdcage with the Yixuan – Trails of Ink outfit.

This update resolves a bug where some Agents’ abilities that were supposed to activate only when an enemy was stunned were triggering incorrectly, even when the enemy hadn’t actually been stunned.

This update resolves a problem where Agent Anton wouldn’t always complete his Piledriver Attack after using Assist Follow-Up: Limit Burst and Drill Attack, despite the skill description. Now, his combat actions will consistently match how the skill is intended to work.

This update resolves a problem in Hollow Zero where Agent Corin wouldn’t receive Energy and Decibels as expected when using her Chainsaw Operation Manual and landing consecutive hits with the chainsaw on enemies.

This update resolves a bug in Mindscape Cinema 02: Full of Colorful Company where Agent Yuzuha would occasionally only have one teammate’s Chain Attack available when initiating Chain Attacks in battle. This happened due to a specific effect within the Mindscape.

We’ve refined the description for Agent Seed’s Mindscape Cinema 01: Hibernation Period to make it clearer. This change only affects the text itself and doesn’t alter how the skill works.

Okay, so as a huge fan, here’s how I understand the change: Now, when this character enters the fight or uses their ultimate ability, they’ll get an extra 40/20 Steel Charge. It’s a nice boost that should really help them power up faster!

This ability now grants an extra 40/20 Steel Charge when the unit enters the battle or uses its Ultimate ability.

▶ Enemies

• Fixes an issue where, under certain circumstances, some enemy models would behave abnormally.

▶ Systems

This update resolves a problem where Drive Disc details would sometimes vanish while navigating the Drive Disc menu with a controller.

▶ Gameplay

This update resolves a problem that sometimes caused unexpected behavior when moving between different screens within the Suibian Temple area of the game.

This update corrects a text error for the ‘Clarity’ buff in Deadly Assault. The description was inaccurate, but the buff itself—which increases Agent Max HP by 25% and Sheer DMG by 15%—hasn’t been changed. This fix only improves the clarity of the buff’s description.

▶ Environments

• Fixes visual issues affecting the models for some NPCs.

▶ Others

• Fixes some text typos.

This update refines the text in a few languages, making it clearer and correcting any errors. These changes are purely cosmetic and won’t impact how the game plays.

• Fixes text errors in some missions, interfaces, and descriptions.
