On September 24, version 4.0 'The One Who Answers the Door' officially went live, and the mist around Camelot Castle rolled in with it: the main story pushes deep into the castle, headlined by the new 6-star Huntsworn Lilya (Star) and the brand-new Drake (Beast), with 4-star Glyndwr (Beast) joining them. The rewards are just as generous — a limited-time 40-pull login event and a guaranteed NEW 6-star login gift, both on the clock.
These two rewards deserve your attention before the banners themselves — log in a day late and you could lose a day of claims. As for how to build the new characters and how the new systems work, there is plenty to untangle. This Reverse: 1999 beginner's guide walks through it piece by piece; read it before you log in and you will know exactly where you stand.

Version 4.0 at a Glance: New Main Story and New 6-Stars
Version 4.0 is the headline patch of the 2026 Suitcase Tour Celebration, with the main story unfolding in the mists around Camelot Castle: following the clues of the flying witch, players slip into the castle and rescue the 'Lady of the Lake,' in a tale tied to the 'Soul.' As the celebration's flagship patch, the opening certainly lives up to the occasion.
New Characters and New Psychubes
Three new characters debut this patch: the 6-star Huntsworn Lilya (Star), the 6-star Drake (Beast), and the 4-star Glyndwr (Beast). The Reverse: 1999 character tier list 2026 has the details: Huntsworn Lilya is a celebration version of an existing character and carries the Star attribute, while Drake is an entirely new face with the Beast attribute. Version 4.0 also launches new Psychubes — their names and effects are listed in the patch notes, and for exact stats, go by the in-game Psychube screen.
One more thing: Psychubes are the easiest upgrade to overlook in this game. Plenty of newcomers dump every resource into Insight, and by the time they turn to Psychubes there is nothing left — a genuinely frustrating way to lose ground.
How Far to Push the Main Story
The 4.0 main story is not just narrative — it also gates new systems and event entries. The bar for 'far enough' is simple: once the Wonderland in the Cracks and Portraits of the Past entries are both unlocked and all daily resource stages are open, you can stop and focus on building. Catch up on the rest of the story when you have time; it does not affect current-patch gains.
Now that you know the characters, on to the real question: if you pull them, which team do they slot into? Let's dig in.

Lilya and Drake: Building Around Attributes
The two new 6-stars carry different attributes, so their team logic is completely different — the slots are not interchangeable. Lilya is Star and Drake is Beast; put either on the wrong team and the investment is wasted. Keep that straight from the start.
What Each 6-Star Fills
Star teams have long lacked a reliable high-rarity damage option. With Lilya on board, the building space for Star teams opens up considerably, especially in stages that call for Star-attribute advantage. She is not locked to any specific team, which makes her a true 'drop-in and play' pick.
Beast teams have always been fragile under pressure and tend to lose units in high-damage stages — Drake fills exactly that gap. His exact skill mechanics have not been detailed in the official patch notes yet, so if you are planning to pull, watch the in-game skill preview first before committing; pull resources are precious, so do not act on impulse.

The 4-Star Glyndwr
The value of a 4-star is low-cost gap filling. Glyndwr is Beast-aligned, making the character a solid transitional piece for Beast teams or a utility option for low-investment stages. Do not pour high-value materials into a 4-star — unless you genuinely lack that slot, the investment will not pay off.
With teams sorted, it is time to talk about how to spend your resources.
Upgrade Order: Insight, Psychubes, Resonance
When resources are tight, your upgrade order decides how fast you clear the main story. It boils down to one line: Insight first, Psychubes second, Resonance last. Do it backwards and even 'half the results for twice the effort' would be an understatement.
Insight is the foundation. Insight unlocks passives and the level cap, so push your mains to the current version cap before anything else. Insight materials are split by attribute, so do not waste stamina on the wrong attribute stage — farming the wrong stage is the most common rookie mistake.
Psychubes scale off base stats. Psychubes grant percentage bonuses, so the higher a character's base stats, the greater the return — which is why Psychubes must come after Insight. Reverse the order and the Psychube bonus is wasted on low base stats.
Resonance is a long-term project. Resonance pays off less than the other two in the short term, and the classic newcomer mistake is piling into Resonance first, only to hit an Insight wall and stall the main story. There is no need to rush — long-term content can wait.

Rewards: How to Claim the 40-Pull Login Event
On the 4.0 reward list, the limited-time 40-pull login event and the guaranteed NEW 6-star login gift are the two you cannot afford to miss. Banners can be pulled at any time, but these two disappear when their windows close, so they take priority.
Start with the login event. The first thing to do after logging in is check in, not pull. The logic is simple: login rewards accumulate daily, so a missed day is a day lost, while pulls can be saved and spent whenever you like — a missed check-in can never be made up. Those 40 pulls are sitting right there; every skipped day is a real loss.
Next, the guaranteed NEW 6-star. 'Guaranteed NEW 6-star' means the character you receive is one you do not own yet: veterans get a collection gap filled, newcomers get a high-rarity combatant outright. Do not rush to build them the moment they arrive — check how they fit your current teams first. A poor fit only ties up materials.
Finally, the self-select 6-star Euphoria event. Its value lies in filling a key slot, and the selection rule is one line: if you lack damage, pick damage; if you lack support, pick support — do not just grab whoever 'looks strongest.' The strongest is not always the right fit; the right fit is what deserves the investment.

Wonderland in the Cracks and Portraits of the Past
Version 4.0 adds two new systems, 'Wonderland in the Cracks' and 'Portraits of the Past,' along with 'Thames Silhouettes.' The official patch notes list their names and release pacing, but the actual gameplay is something you have to experience in-game.
Wonderland in the Cracks is an exploration and collection system tied to main-story progress. Just follow the main story — there is no need to grind it separately, or you may get stuck on unlock conditions and waste your effort.
Portraits of the Past leans toward retrospectives and archives; it is long-term content that does not affect current-patch power. Work through it at your own pace for the rewards, and keep it below the main story and events in priority.
In the end, 4.0 still comes down to the two things from the top of this guide: never break the 40-pull login streak, and check team fit before investing in the guaranteed NEW 6-star. Nail those two and you have the skeleton of the patch; everything else is just filling in the details. The mist over Camelot has already gathered, and the door stands within it — whether you walk through, and when, is up to you.
