March 7th

Single-target shielder and counter attacker

Released Apr 26, 2023

March 7th is an Ice Preservation character who protects one ally with a DEF-scaling shield and counters enemies that attack shielded allies. Use her when you need focused protection, extra retaliatory hits, or a chance to Freeze enemies; her kit is less suited to broad team shielding.

March 7th GUIDE

Understand March 7th

Useful when…

  • Protect an ally who is likely to draw attacks, especially when their HP is at least 30%.
  • Add counters when enemies attack shielded allies.
  • Use her Ultimate or Technique when Ice damage and Freeze control are useful.

How her shield and counters work

The Power of Cuteness gives one ally a shield that absorbs damage based on March 7th's DEF plus a flat amount, lasting 3 turns at the listed level. If the chosen ally is at 30% HP or higher, enemies are much more likely to target them. When an enemy attacks a shielded ally, Girl Power counters that attacker; it can trigger twice per turn. The shield therefore protects one target while also creating counter opportunities. Her Ultimate hits all enemies and has a 50% base chance to Freeze each hit target for 1 turn. Frozen enemies cannot act and take additional Ice damage at the start of their turns. Her Technique also has a 100% base chance to Freeze a random enemy for 1 turn after entering battle, with additional Ice damage at the start of that enemy's turn while Frozen.

Practical use and build direction

Prioritize DEF when you want the shield to absorb more damage: its scaling is explicitly tied to her DEF. Choose the shield target deliberately. A high-HP ally meets the stated condition for increased enemy targeting, which can help concentrate attacks and generate counters, but also exposes that ally to more incoming hits. Her Ultimate's Freeze is a base chance, so it is a control opportunity rather than a guaranteed interruption. The Technique's Freeze targets a random enemy, so it is less precise. Her Basic ATK and Ultimate damage scale with ATK, but the shield and counter utility are the clearest role-defining mechanics.

Improvement priorities and investment

For a protection-focused build, invest in The Power of Cuteness first because it directly determines the single ally shield's strength. Girl Power is a reasonable next focus when you want more counter damage; Glacial Cascade matters more when you rely on its area damage and Freeze attempt. Her traces include DEF and Effect RES boosts, alongside Ice damage boosts. Trace unlocks have prerequisites, so plan around the listed branches rather than assuming every bonus is immediately available. Promotion raises her character stage and has separate costs from ability levels and trace unlocks.

Limitations and common mistakes

Her skill shields only one ally, so it does not provide the teamwide coverage of a broad defensive effect. The increased targeting condition applies only when the shielded ally's current HP percentage is at least 30%; it is not a universal taunt. Counters require an enemy to attack a shielded ally and are capped at two triggers each turn. Freeze is chance-based, and the Technique chooses a random enemy. Do not treat either Freeze effect as guaranteed control.

Limitations and tradeoffs

  • Her shield is focused on one ally rather than the whole party.
  • The HP condition that increases enemy targeting can help counters but draws danger to the protected ally.
  • Freeze and Technique targeting are not fully reliable or player-selected.

Common mistakes to avoid

  • Expecting the shield to cover multiple allies.
  • Choosing a shield target below 30% HP and expecting the increased enemy targeting condition to apply.
  • Assuming the Ultimate or Technique will Freeze a chosen enemy every time.
  • Ignoring the per-turn limit on counters.
