The [Sanctuary of Ink] version update went live on October 15, 2026, and with it the patch's first Chartered Headhunting banner: [Rejuvenation], headlined by the new 6★ operator Si. The banner runs until Nov. 5, 2026 at 11:59 (server time), an explicit end date rather than the usual "runs until the next version update". Its companion weapon banner is [Seal of Jade Issue], with Jade Vessel (Greatsword) as the rate-up 6★.
This guide collects everything the official notices actually state: the banner window and participation criteria, the full 6★ pool and the rotation rule, the three pull-reward tracks, the Arsenal Ticket values, the [Spirit's Restoration] sign-in and [Combat Drills] trial, and the [Seal of Jade Issue] weapon list. For the version itself, see our [Sanctuary of Ink] version guide; for launch-day logistics, the pre-download and maintenance guide.
[Rejuvenation] at a glance
- Banner: [Rejuvenation] Chartered Headhunting
- Rate-up: 6★ operator Si
- Availability: After [Sanctuary of Ink] version update – Nov. 5, 2026 at 11:59 (server time)
- Participation criteria: complete the main mission [Chapter I Process I: Break the Siege]
- 6★ pool: Si / Typhoeus / Liino / Ember / Lifeng / Ardelia / Last Rite / Pogranichnik
- Currencies: [Spirit's Restoration HH Permit], [Chartered HH Permit], or Oroberyls
Two rules matter before you spend. After three Chartered banners the rate-up 6★ drops out of the Chartered pool, and it is never added to Basic Headhunting. So if you want Si, this window or a later rerun is the route.
Si: what the official material says so far
Si is the 6★ rate-up of [Rejuvenation], and she is the operator this patch introduced. Two official notices show she is new rather than a rerun: the October 8 Game Stats Widget update adds new Discord operator themes for "Si" and "Argent Flow", and the [Sanctuary of Ink] DEV Comm (October 7) names a farm area called [Si's Painting], unlocked through the side mission [A Painting Open for Business], where the new [Auto-Farmer] facility handles Auto-Germinate and Auto-Harvest.
What we do not have yet: our database carries no operator record for Si, so this site cannot show her class, element, weapon type, voice cast or splash art at the time of writing. Rather than guess at a kit, we are flagging the gap. As soon as the data catch up, she lands in the operator index, next to the cast list at voices and the official artwork gallery.
The [Combat Drills] trial is the practical way to test her without pulling: it hands you a preset team that includes Si. See the companion events section below for what clearing it pays.
The 6★ pool and how the rotation works
Chartered Headhunting pools are eight 6★ operators. [Rejuvenation] carries over seven and swaps in the new debut:
| # | 6★ operator in the [Rejuvenation] pool | Notes |
|---|---|---|
| 1 | Si (no operator page yet) | Rate-up on this banner |
| 2 | Typhoeus (no operator page yet) | Rate-up on [Winter Hunt] (September) |
| 3 | Liino (no operator page yet) | Rate-up on [Good Morning from Your Dawnstar] (August) |
| 4 | Ember | Carried over from the previous pool |
| 5 | Lifeng | Carried over from the previous pool |
| 6 | Ardelia | Carried over from the previous pool |
| 7 | Last Rite | Carried over from the previous pool |
| 8 | Pogranichnik | Carried over from the previous pool |
Liino opened the pool in the [Good Morning from Your Dawnstar] banner in August; Typhoeus headlined the [Winter Hunt] banner in September. Si is the third new 6★ to enter the rotation in three versions, so players who skipped a banner still have a path to the older entries through the shared pool.
Pull rewards: Urgent Recruitment, Dossier and Token Tribute
Three milestone tracks sit on top of the banner. Two of them fire on this banner alone; the Dossier deliberately points at the next one.
| Reward track | Requirement | What you get |
|---|---|---|
| Urgent Recruitment | 30 headhunting attempts on this banner | 10 bonus attempts (counts as a free 10×; guarantees a 5★ or better; does not count toward other banner guarantees or reward totals) |
| Headhunting Dossier | 60 headhunting attempts | 1 [Headhunting Dossier], auto-sent to your Valuables Stash; it converts to 10 HH Permits for the specified Chartered banner once the next one starts, and those permits expire when that banner ends |
| Token Tribute | Every 240 headhunting attempts | 1 Token of the Rate-UP 6★ operator of that banner |
What every pull feeds: Arsenal Tickets
Operator headhunting also mints [Arsenal Tickets], which are spent at the in-game [Acquisition Center - Arsenal Exchange]. The conversion is flat by rarity:
| You pull | Arsenal Tickets earned |
|---|---|
| 6★ operator | 2,000 |
| 5★ operator | 200 |
| 4★ operator | 20 |
This is the bridge between the operator banner and the weapon banner: pulling for Si is also how you fund weapon purchases. For how the weapon side of the economy works, see LTO weapon banners explained.
Companion events: [Spirit's Restoration] sign-in and [Combat Drills]
- [Spirit's Restoration] limited-time sign-in: sign in for a total of 7 days to earn rewards such as [Spirit's Restoration HH Permit]×5. The [AIC Quota Exchange] runs limited-time special deals at the same time, including [Spirit's Restoration HH Permit]×5 for AIC Quota.
- [Combat Drills] operator trial: a trial version of the 6★ operator Si with a preset team. Clear the specified stage to claim Oroberyl×100, an [Arsenal Defense Crate], Mark of Perseverance, and other rewards. The [Arsenal Defense Crate] holds a Fully Artificed Level 60 Gear Set fitted to the trial operator, so the trial is also a free gear benchmark.
The sign-in event is the cheapest source of pulls on the banner. If you are on the fence about Si, log in for the week first: five discounted permits plus the free 10× from Urgent Recruitment at 30 attempts changes the maths considerably.
Companion LTO: [Seal of Jade Issue]
The weapon banner paired with this operator banner is [Seal of Jade Issue]. Availability: Opens after [Sanctuary of Ink] version update; ends after 3 [Chartered Headhunting] banners (starting from [Rejuvenation]). The rate-up is Jade Vessel (Greatsword).
| # | 6★ weapon in [Seal of Jade Issue] | Type |
|---|---|---|
| 1 | Jade Vessel — Rate-UP | Greatsword |
| 2 | Former Finery | Greatsword |
| 3 | Wedge | Handcannon |
| 4 | JET | Polearm |
| 5 | Chivalric Virtues | Arts Unit |
| 6 | Sundered Prince | Greatsword |
| 7 | Eminent Repute | Sword |
Two mechanics carry over unchanged from earlier issues. Each issue spends [Arsenal Tickets] and returns 10 random weapons from the available list, including at least one 5★ or better. And performing a set number of issues on a banner pays the banner's specific [Arms Offering Crate] (Arms OC) or the Rate-UP 6★ weapon in alternating order; that counter resets when the banner ends and does not carry over. Our crates and selection boxes guide breaks down what the Arms OC crates are, and the weapons guide maps the type names (Greatsword, Handcannon, Arts Unit, Polearm, Sword) used above.

Frequently asked questions
When does [Rejuvenation] end?
Nov. 5, 2026 at 11:59 (server time). Unlike most earlier Chartered banners, this one has an explicit closing date instead of "until the next version update".
Is Si new or a rerun?
New. Official notices list "Si" as one of two newly added operator themes (Oct 8 widget update), and this is her first Chartered Headhunting as rate-up.
Can I get Si later if I skip the banner?
The rate-up 6★ leaves the Chartered pool after three Chartered banners and is never added to Basic Headhunting. Plan on this window or a future rerun, not Basic.
Do I have to pull to try Si?
No. [Combat Drills] offers her as a trial operator with a preset team, and clearing it pays Oroberyl×100 plus an [Arsenal Defense Crate].
What does Si cost in a worst case?
Our data does not carry her banner record yet, so we publish no pity numbers for her specifically. The general pity and soft-pity maths for Chartered banners is in the headhunting guide.
