HaruBuild and Guide

Haru is one of the best DPS units currently in the Beast faction, with incredibly high multipliers and a global attack buff of a whopping 30% when there are ally units nearby. In story stages, the criteria to achieve the attack buff should be easily obtained since you would usually run a tank alongside Haru as well as a healer or secondary melee units such as Mica, Seeha, or even Catherine.

She also has an innate camouflage kit in her artifact, making her untargettable unless AoE, while boosting her own physical and magic resistance, offering her a bit more durability to an otherwise fragile kit. Her S2’s bleed also reduces target mana recovery by half, which can be very useful against frontlines like Claire or Petra who will heal for a big amount with their M1s, and delaying that might push your DPS to take the frontline. Her M1 is also a great tank shredder, ignoring 40% of target DEF while having a massive 380% damage multiplier. If the enemy only runs 1 frontline, using Haru’s ult could easily destroy it as it doubles the damage to a massive 860% while still ignoring 40% of the DEF.

An issue with her kit is the need for more access to backline units, and this will become a glaring weakness towards later stages if your Haru is not hyper-invested due to the obscene amount of healers, disrupters, and pure stats the enemy will bring against you. Without being able to reach backlines, Haru needs to be able to shred the tank as soon as possible before your own frontline collapses from the enemy DPS.

Her S3 attack buff may also be gimmicky, as the effect will no longer be in effect if your frontline dies and there are fewer than 2 allies beside Haru, bringing your team DPS down significantly. That said, hyper-invested Harus have no issue destroying tanks, making stages with single frontlines a breeze once Haru opens the access to enemy backlines.

Single Bosses

Haru is currently one of the top 4 hyper carries, the other 3 being Vivienne, Linzy and Violette. Her 30% teamwide attack boost alone is already a huge asset to any boss comps, while her kit of targeting single enemies truly shines in boss stages. Being able to stun is just the sprinkle to the cupcake, especially for future bosses with similar mechanics. Do note that you need 2 other units besides Haru for the 30% attack buff to proc, and this can sometimes go away if your frontlines walk too far from Haru, which will heavily affect your score.

PVP

Haru is a rare pick since she is a squishy melee unit, and her invisibility will not save her from the rain of AoE damage in most PVP staples like Vivi and Naiah. Not being able to use ult also vastly reduces her DPS, which might lead to you not being able to burst down the enemy tank, while yours starts falling apart.
