Chaos Zero Nightmare: Haru Guide – Best Teams, Build and Role

Most first attempts at Haru build her like a burst nuke, then wonder why she fizzles. In Chaos Zero Nightmare, Haru is a Justice Striker who wins by replaying one card — Anchor Shot — as many times as your team can fund. Get the engine right and she becomes one of the most reliable scaling carries in the roster. Get it wrong and she stalls on AP.

The short version

• Role: Justice Striker, scaling DPS carry built entirely around repeated Anchor Shot casts — not a single big finisher.
• Anchor Shot scaling cap: 10 stacks. The cap was raised from 5 to 10 in the February 4 patch, which is why older material still cites 5.
• Key enabler: Anchor Pointer fetches Anchor Shot from your deck or discard, but it does not naturally Retain — so add Retain through Epiphanies.
• Gear: 2/2/2 Black Wing + Cursed Corpse + Executioner’s Tool, or Line of Justice with crit pieces. Prioritise Crit Chance → Crit Damage → Attack.
• Best partner: Narja for zero-AP Anchor Shot windows; Mika and Cassius for a steadier AP-and-cycle floor.

What Haru’s role actually is

Haru is a scaling DPS carry. The whole plan is to make Anchor Shot appear more often, cost less, and hit harder as its scaling ramps over a turn. A burst finisher wants one perfect window and a single oversized hit. Haru wants the opposite: turn compression — cheaper plays, more cycling, more retrieval, more chances to fire the same attack again.

Here is the number that decides how you build her. Anchor Shot scales up to 10 stacks. That cap was raised from 5 to 10 in the February 4 patch, which is exactly why you still see both figures floating around — older clips were recorded against the old 5-stack ceiling. Build for the current 10: every extra cast in a turn pushes you toward a payoff that is now twice as high as it used to be.

How you obtain Haru

Haru is a recruitable roster unit you build around once you own her, not a story-locked character. Recent update cycles have spotlighted newer additions rather than Haru, so before you spend currency, check your in-game recruit pool and active event notices for her current availability. If you already have her, the only question that matters is whether your account can fund an AP-heavy combo pattern.

How to make Haru perform well

Haru lives or dies on one resource: AP. When she looks bad, it is almost always because the team cannot fund her combo lines — expensive hands, awkward sequencing, dead turns. When she looks great, the rest of the squad is quietly paying for her casts.

Step 1: Treat AP as part of Haru’s damage stat

Do not think of AP support as a comfort pick. For Haru it is offensive scaling. Every point of AP, cost reduction, or zero-cost interaction can become another Anchor Shot cast — and with the cap at 10, another cast almost always beats overstacking raw attack on gear.

Step 2: Cycle Anchor Shot, do not admire it

The best Haru turns are built around seeing Anchor Shot again as fast as possible. Draw, search, discard retrieval, and hand-fixing all reduce the dead cards between one cast and the next. If a line gives you a slightly weaker immediate hit but improves your odds of replaying Anchor Shot in the same turn, take it.

Step 3: Use Anchor Pointer carefully

Anchor Pointer is Haru’s most important enabler because it fetches Anchor Shot from your deck or discard. The catch: it does not naturally Retain. If you generate it too early or hold it in a bad sequence, you lose much of the consistency it is supposed to give you. That is why Retain-adding Epiphanies are so valuable — they protect the one support card that keeps your main damage card circulating.

Best teams for Haru

The pattern is always the same: AP generation + card cycling + damage amplification. Pick the support core that matches your roster.

• Narja — the highest ceiling. She opens zero-AP Anchor Shot windows, and a full turn of free casts is exactly what the 10-stack cap is built to reward. Run her when your account already has the AP sustain and cycling to keep the rest of the turn moving.
• Mika — AP support plus healing makes Haru’s greedier combo turns far safer. The dependable floor.
• Cassius — a card-cycle and search partner who helps Haru find her pieces and avoid bricking on setup.

Default to a Narja core if your roster supports it; fall back to Mika and Cassius when your runs feel unstable or your account is less developed. And if you cannot field reliable AP support plus some cycling at all, Haru stops being a carry and becomes a card-hungry project — that is the signal to bench her until the pieces arrive.

Gear and stat priorities

Gear is the tightest call in the build. Run a 2/2/2 mix of Black Wing, Cursed Corpse, and Executioner’s Tool, or lean into Line of Justice with crit-oriented pieces depending on the rolls you actually have. Either way the priority order is the same:

• Critical Chance first — reliable crits matter more than a single big number when you are casting the same card up to 10 times.
• Critical Damage second — it multiplies every one of those crits.
• Attack third, with Justice damage valued where it appears.

When you are comparing two pieces and one gives cleaner crit consistency while the other only raises flat attack, take the crit piece. Repetition multiplies reliable damage — that is the whole character in one sentence.

Cards and upgrades that matter

Haru’s secondary cards are setup tools. If a card is not helping you reach, replay, protect, or cheapen Anchor Shot, it needs a strong reason to stay.

• Anchor Shot is the center of the build. Everything else is supporting cast.
• Anchor Pointer is premium because it fetches your core card from deck or discard.
• Retain-oriented Epiphanies preserve combo pieces and smooth out awkward hands.
• Cost reduction, duplication, and extra cycle fit Haru better than raw single-cast boosting.
• Anchor Drop is a common cut when shields do not matter for the content you are clearing.

Keeping too many “nice to have” defensive or filler cards slows down a deck that is supposed to be accelerating. Trimming is not glamorous, but it is often the difference between a Haru turn that fizzles and one that spirals into repeated Anchor Shot pressure.

Common mistakes with Haru

• Building her like a one-turn nuke. She wants repeated casts toward the 10-stack cap, not a single oversized hit.
• Ignoring AP support. If the team cannot feed her, the whole deck feels worse than it should.
• Overvaluing raw attack. Crit Chance and Crit Damage pay off more across many casts.
• Holding Anchor Pointer badly. It does not Retain on its own — add Retain or play it at the right moment.
• Keeping too many non-engine cards. Every slot should make Anchor Shot happen more often.
• Building for the old 5-stack cap. It is 10 since the February 4 patch — build for the higher ceiling.

Practical takeaway

Build Haru if your roster can fund repeated Anchor Shot turns; bench her if your account still lacks AP support and card-fixing. Stack Anchor Pointer to fetch the card, add Retain through Epiphanies so it sticks, gear for crit, and pick Narja for the highest ceiling or Mika and Cassius for the safer floor. Respect the 10-stack cap and the engine pays off — ignore it and you are spending carry-level resources on a character who never shows her ceiling. Newer to the roster? Start with our reroll guide.
