Dante’s Vanguard familiar in Anime Vanguards is called the Familial Jewel, and it is not a drop you can farm from a raid boss or buy with tokens. It comes from a single trial, and the trial has to be beaten in full.
Quick answer: Talk to the Reasonable Person NPC in the Trials area of the lobby, pick Martial Island (Trial: Dawntay) on Normal, and survive all 15 waves. The Familial Jewel is awarded on completion.
What the Familial Jewel is and who can use it
The Familial Jewel is a Vanguard rarity familiar, which means it is bound to one specific unit and nobody else. That unit is Dawntay (Jackpot). Vanguard familiars also sit outside the usual customization systems, so there is no rerolling stats and no corrupting them with Corruption Crystals or Rigged Dice.
In exchange, the stats are fixed rather than rolled, and the numbers are large. The headline figure is an 8000% damage value tied to the In Debt passive, alongside two more passives that come with the same item.

The important thing to know up front is that your account’s best units do not matter here. Trials hand you a preset selection of units instead of your own loadout, so there is no point grinding a team before you queue in. Everyone attempts the run with the same tools.
Martial Island sits in Story Act 1, and the trial version of it runs on Normal difficulty. The run is 15 waves long, and the reward only pays out if you survive to the end. Leaking enough enemies to lose ends the attempt with nothing.
How to start Trial: Dawntay on Martial Island


How to equip the Familial Jewel on Dawntay (Jackpot)

How to confirm the familiar worked
Open the Familiars tab and select the Familial Jewel. If it is applied correctly, the item card shows the Vanguard rarity tag, the 8000% DMG line, and the note that it is exclusive to Dawntay (Jackpot). The three passives, In Debt, Don’t Say It and Royal Guard, are listed on the same panel.

The other place to check is the unit itself. Dawntay (Jackpot) will display the familiar attached in the unit view, and the Equip button on the jewel switches to Unequip once it is in use.
Why the reward does not appear
There are only a couple of reasons this goes wrong, and both are tied to the run itself rather than your account.
- You did not finish all 15 waves. A partial clear does not award the jewel.
- You entered a different trial or stage. The reward is tied specifically to Trial: Dawntay on Martial Island, not to the regular Martial Island story stage.
Note: since the trial forces its own unit selection, a failed attempt is not a signal to go build a better team. It is a signal to replay the same fight and place the assigned units more efficiently.
Once the jewel is on Dawntay (Jackpot), the unit is permanently upgraded for as long as the familiar stays equipped, and there is no rolled stat to chase afterwards. That makes this a one-and-done clear rather than a grind, which is unusual for familiars in Anime Vanguards and the main reason the trial is worth doing early.
