Topaz, Senior Manager of the Strategic Investment Department in the Interastral Peace Corporation, and leader of the Special Debts Picket Team.

Already a member of the "Ten Stonehearts" at a young age, Topaz's core stone is the "Topaz of Debt Retrieval."

Her partner, the Warp Trotter "Numby", is also capable of acutely perceiving where "riches" are located. It can even perform jobs involving security, debt collection, and actuarial sciences.

Presently they are traversing the cosmos together, chasing down various debts and liabilities that negatively influence the IPC's commercial ventures.


  • Basic ATK: Deficit...


Still no repayments?

Deals Fire Damage equal to 50% - 110% of Topaz's ATK to a single target enemy.

  • Skill: Difficulty Paying?


Smash them up, Numby!

Inflict a Proof of Debt state on a single target enemy, this state will increase the Damage the target receive from follow-up attacks by 25% - 55%. After that, Numby attacks the target enemy and dealing Fire Damage equal to 75% - 165% of Topaz's ATK. This attack is considered a follow-up attack.

If no enemy targets have Proof of Debt state during an allied turn (at the start of your turn or action), Topaz can inflict this state on a random enemy.

Proof of Debt will only take effect on the most recent target and when Topaz is knocked down, Proof of Debt will be disappeared.

  • Ultimate: Turn a Profit!

The market is unpredictable...

Huh? Right! Investing in victory... means playing the long game!

During turns where Numby does not take action, if a target in the Proof of Debt state receives a follow-up attack, Numby's action will be Advanced Forward by 50%. The action Advance Forward effect cannot be triggered during Numby's own turn.

When Topaz is defeated, Numby disappears.

  • Technique: Explicit Subsidy

It's a bull market.

Gotta know the risks...

Topaz summons Numby for exploration. Numby will automatically search for Basic Treasure and Warp Trotter in a certain range.

After Topaz uses this Technique to enter the battle, she can regenerate 60 Energy after Numby's first attack; also a small amount of additional credits is awarded if Topaz is still in the team after winning a battle (Max 10,000 bonus credits that can be earned in every day).

This Technique also works for winning battles in the Simulated Universe, but instead of credits, Topaz will receive a small amount of Cosmic Fragments and a chance to receive a random Curio.

About Other Characters編集

This part is about what Topaz thinks about the other characters in Honkai: Star Rail.

They've always liked shiny things — gold coins, gems, you name it. They're like a big fat investment account accruing interest... Guess I should've just named them "Piggy."


In the IPC — no — even just the Strategic Investment Department — there are plenty of unsavory characters I don't care for. They may be my colleagues, but we're not the same. Take Aventurine, for instance... I sincerely hope you never have to deal with him.


Lady Jade is like nobility to me, beautiful and capable. She is always so kind and willing to guide and support the younger generation! When I think about the first time I met her, I still get nervous... Time does fly.


The supreme guardian of Belobog... Well, she's an impressive little girl well beyond her years in maturity... Huh? You're saying I'm about her age? No, no, no, totally different circumstances, no comparison at all...


I've heard about Himeko of the Astral Express — my colleagues were gossiping about how beautiful and knowledgeable she is. If I ever get the chance, I'd love to meet her.

The most mysterious character on the Astral Express is that conductor — the one who looks like a little creature... Their reputation precedes them. If they're as interesting as the rumors suggest, I'll definitely have to meet them sooner or later! And hopefully, I'll get to pet them too!

Lady Asta! Now that's a real lady if I ever saw one. You'll never guess just how wealthy she really is!


Stellaron Hunters? We aren't acquainted. Never worked with them on any projects. Supposedly those guys are hard to get in touch with, but they have an unexpectedly good credit record — which I value far more than any groundless conspiracy theories.
