Reverse: 1999 is celebrating its third anniversary with one of its biggest updates yet. Version 3.7, titled On Another’s Sorrow, brings the finale of the 3.0 story series, two new 6-Star Arcanists, a free 6-Star character, new events, Euphoria upgrades, special banners, new garments, and a huge amount of free summons. The anniversary version officially launched on August 13, 2026, and runs until September 24, 2026. With so much content arriving at once, there is plenty for both new and returning players to explore.

Here is everything you need to know about the Reverse: 1999 3rd Anniversary update, including the new story, characters, anniversary rewards, events, Euphoria upgrades, and special banners.

Reverse: 1999 3rd Anniversary – On Another’s Sorrow

The biggest addition in Version 3.7 is the new main story chapter, On Another’s Sorrow. It continues the ongoing 3.0 story arc and serves as its finale, giving players another major chapter in Vertin’s journey through the world of Reverse: 1999.

The new story comes with its own stages and rewards, giving players another reason to progress through the campaign during the anniversary celebration. Alongside the main story, the update also introduces dedicated character stories for the two new 6-Star Arcanists, Rhiannon and Ms. Stranger, allowing players to learn more about their characters while earning additional rewards.

Anniversary Celebration Event – Peace at a Price

The anniversary also introduces Peace at a Price, a special celebration event containing several activities and rewards.

Players can participate in the anniversary content while progressing through the update and collect valuable materials and other rewards. The version also adds Truth a Posteriori, a resource-management survival mode, giving players another gameplay experience beyond the regular story stages.

There is also an update to The Syndrome of Silence, alongside the return of 8-Bit Arcade Remix: Beach Battle. Together, these activities make Version 3.7 much more than a standard character update and give players several ways to earn rewards throughout the anniversary period.

Up to 155 Free Summons

One of the biggest attractions of the third anniversary is the huge amount of free summons available during Version 3.7. The official game listing advertises up to 155 free summons during the anniversary celebration. This includes login rewards, anniversary activities, and other limited-time campaigns.

Players can receive 67 summons simply through anniversary login rewards, making it particularly worthwhile to log in consistently throughout the event. The login campaign is split into multiple periods, so players should make sure they do not miss the second half of the sign-in rewards.

Free 10-Pull for Rhiannon’s Banner

Players who log in during the anniversary can receive a free Decatone, which provides 10 summons on Rhiannon’s limited banner, A Newly Hatched Chapter. The official event schedule lists this reward from the Version 3.7 launch on August 13 through September 24.

20 More Free Summons From Sign-In Rewards

The On Another’s Sorrow sign-in event provides another 20 Unilogs in total. The campaign is divided into two seven-day periods, allowing players to collect 10 summons from each part as long as they log in during the corresponding period.

Additional Anniversary Summons

The anniversary celebration also contains additional login and event rewards, including the 15-summon anniversary bonus that begins on September 1. Because several rewards are tied to specific event periods, players should check the in-game event calendar rather than assuming all anniversary rewards are available from day one.

Free 6-Star Coppélia

The anniversary becomes even more generous with the addition of Coppélia, a new 6-Star character who can be obtained for free. Coppélia is a Mineral Afflatus Arcanist and is one of the headline rewards of the third-anniversary celebration.

Players can obtain her simply by logging into the game during the anniversary event. Her addition gives free-to-play players another valuable 6-Star character without requiring them to spend their saved pulls. The update also includes a new garment for Coppélia, making her one of the central characters of the anniversary celebration.

Free Silverwing Eagle and Lady by the Lake

Version 3.7 does not stop at Coppélia. Players can also obtain the new 5-Star Silverwing Eagle, a Plant Afflatus character, by progressing through the anniversary story content. The official event information states that players can clear the required Chapter 13 stages to obtain Silverwing Eagle and her related rewards.

The update also introduces Lady by the Lake, a new 4-Star Plant Afflatus character. This gives players several new characters to collect during the anniversary period without relying entirely on the premium character banners.

New Limited 6-Star Character – Rhiannon

The main limited character of the third anniversary is Rhiannon, a 6-Star Arcanist with the Beast Afflatus. Rhiannon is designed as a highly flexible support character who can fit into a wide variety of teams. Her kit revolves around Rapport, Rhaptor’s Kinship, additional AP generation, and powerful team-wide buffs.

One of the most notable parts of her kit is her ability to generate additional AP for herself and gain additional actions. This allows her to provide more support while also contributing damage. Her skills can weaken enemies’ critical defenses and provide various offensive and defensive enhancements to herself and her allies. Her Ultimate places her into a special state where her Incantations no longer consume AP, while also improving the Attack and HP of her allies based on her own stats.

Rhiannon’s combination of general-purpose buffs and flexible mechanics makes her one of the most universally useful supports introduced with the anniversary version.

Rhiannon’s Banner

Rhiannon’s limited banner is A Newly Hatched Chapter. It launched alongside Version 3.7 on August 13 and remains available throughout the anniversary version until September 24, 2026. The banner features Rhiannon as the featured 6-Star character, alongside 5-Star characters Ulu and Avgust. This makes the anniversary period an excellent opportunity for players who have been saving resources specifically for Rhiannon.

New 6-Star Character – Ms. Stranger

The second major character arriving with Version 3.7 is Ms. Stranger, a 6-Star Arcanist with the Mineral Afflatus. Unlike Rhiannon, Ms. Stranger is primarily designed around dealing damage through a more specialized gameplay mechanic.

Her kit revolves around a unique Special Incantation that players need to position correctly within the Spelldock. The location of her cards affects how her other skills function, meaning players need to pay attention to card positioning rather than simply using abilities whenever they appear.

Her gameplay becomes increasingly powerful as she builds her required buffs and prepares her Special Incantation. Once the conditions are met, she can unleash a powerful attack and use her Ultimate to further enhance the damage of her Special Incantation. Ms. Stranger therefore offers a more technical playstyle than a straightforward DPS character.

Ms. Stranger’s Banner

Ms. Stranger receives her own time-limited character banner during the second phase of Version 3.7. The banner Beneath the Guise of Her Cocoon begins on September 3, 2026, and runs until the end of the version on September 24.

Players who are interested in Ms. Stranger should therefore plan their anniversary summons carefully instead of spending everything on the first banner.

Rhiannon and Ms. Stranger Character Stories

Both new 6-Star characters receive their own dedicated story content. Rhiannon’s story is titled The You That’s Meant To Be, while Ms. Stranger’s story is titled A Stranger to Memory Lane.

These character stories provide additional narrative content while also giving players another opportunity to experience the new Arcanists in dedicated stages and earn rewards.

Euphoria Upgrades for Nautika and Regulus

Version 3.7 also expands the Euphoria character enhancement system. This time, Nautika and Regulus receive Euphoria upgrades, giving these existing characters new ways to improve their performance.

The system provides additional growth options for selected older Arcanists and gives long-time players a reason to revisit characters already in their rosters. Players should also take advantage of the materials and other rewards connected to the Euphoria content while the anniversary version is active.

Special Limited-Time Banners

Several special banners are available during the third anniversary, giving players more options for spending their saved resources.

From the Lake’s Heart

From the Lake’s Heart is a special Limited Rerun Selection Banner that allows players to select one eligible previous Limited 6-Star character for Rate Up. The selected character can be changed during the banner period, giving players considerable flexibility when deciding which Limited character they want to target.

The banner begins on September 1 and runs until the end of Version 3.7. This is particularly useful for players who missed previous Limited characters and want another chance to obtain one.

Promise of the Water

Another anniversary banner is Promise of the Water, which allows players to select an eligible non-Limited 6-Star character for Rate Up. The banner also offers a discounted first multi-summon, making it an attractive option for players looking to fill gaps in their permanent roster.

Because the banner focuses on non-Limited characters, it serves a different purpose from the Limited rerun banner and should be considered separately when planning your pulls.

New Garments and Cosmetic Rewards

Version 3.7 also brings a large collection of new cosmetics. New garments are available for characters including Coppélia, Nautika, Fatutu, Name Day, Charon, 37, and Spathodea.

Some cosmetics can be obtained through events, while others are available through the Garment Shop or special anniversary campaigns. The anniversary also introduces the Cut-to-fit Garment, which can be used toward a garment purchase at a discounted Crystal Drop cost.

Final Thoughts

The Reverse: 1999 Version 3.7 – On Another’s Sorrow update is a major anniversary celebration packed with new content. Players get a new main story chapter, two new 6-Star Arcanists, a free 6-Star Coppélia, a free 5-Star Silverwing Eagle, Euphoria upgrades for Nautika and Regulus, multiple event modes, new character stories, special rerun banners, new garments, and up to 155 free summons throughout the celebration.

If you are a free-to-play player, make sure to log in consistently and complete the anniversary activities so you do not miss the limited-time summons and free characters. Meanwhile, players who have been saving for Rhiannon or Ms. Stranger should plan their pulls around the two banner phases. With so much content packed into one version, the third anniversary is easily one of the most rewarding periods for Reverse: 1999 players.
