R1999 Version 3.6 Last & First Principle Content Overview
Reverse 1999 Version 3.6 guide: explore Enigma, new banners, Laplace story events, Recoleta Euphoria, rewards, cosmetics, and key dates before July 23.
Reverse 1999 Version 3.6 is finally here, and it's packed with events, new characters, banners, and rewards worth knowing about before you dive in. Running from July 2 to July 23, 2026, this version is shorter than usual — essentially a half-version — so players need to move efficiently to catch everything before the window closes. Whether you're chasing the new character, clearing events for materials, or stocking up on Unilogs, this guide breaks down everything coming in Ver. 3.6 Last and First Principles.
Bonus tips: If you're looking to top up for the new content, OLD STORE is a reliable platform to get your resources sorted before the version ends.
Reverse 1999 Version 3.6 Contents
The Story: Last and First Principles
Version 3.6 centers on Laplace and a new chapter in his journey. A request, a secret, and a gift arriving at the perfect moment are pushing him to finally seek the answer he has long been searching for. The main event story, Last and First Principles, is available in Story Mode from July 2–22 and Hard Mode from July 9–22, with the Event Shop open until July 23. Players must complete main story 1ST-16 Heaven Apostles to participate. Completing challenges and event tasks earns Deductive Step currency, which can be exchanged in the Cryptography Team shop for high-value rewards including a new 6-Star Psychube The Riddle's Limit, Immaterial Photoscope, Vision Blocks, Delicate Insight Materials, and more.
New Character: Enigma
The headline character of Version 3.6 is Enigma, a 6-star Intelligence sustain unit built for the Dynamo archetype. His banner, [Deciphering Reality], runs from July 2–23 alongside rate-up 5-stars Sweetheart (Beast) and Charlie (Star). Enigma is a non-limited character and will be added to the Standard Pool after three versions, so players who miss this banner will have another opportunity later. The first 10 summons guarantees at least one 5-star or higher.
Ripples on the Water: The Selector Banner
Running alongside Enigma's banner is the [Ripples on the Water] Time-Limited Event Banner, open from July 2–23. This banner lets players freely select one 6-star character for Rate Up from the following pool: Recoleta, Melania, Tooth Fairy, Willow, Tuesday, and Isolde. The first 6-star pull is guaranteed to be the selected character. Subsequent pulls carry a 50% chance of landing the selected character, and if a non-selected 6-star is pulled, the next one is guaranteed. Notably, the first Summon x10 costs only Unilog x7, making it a strong early pull. Guarantee counts carry over to the next Ripples on the Water banner.
Ripples on the Water
Melania is especially relevant here for players building around the new Recoleta Euphoria — without Melania, Recoleta's kit doesn't function properly.
