He taunts, spends his own HP for a Zone that shreds DEF, and scales on Max HP — a carry that needs a healer more than it needs a second buffer.
A Break Effect carry with two Harmony units that raise Break damage and Weakness Break efficiency, and a sustain that keeps Break uptime rather than adding damage.
A single-target Break carry: one Harmony unit raises Break damage, one implants the Weakness he needs, and the sustain is the one that also breaks.
Break damage across a whole wave rather than one target, so both Harmony slots go to Break amplification and the sustain adds Break of its own.
Himeko follows up whenever an enemy is Broken, which turns the standard-warp Erudition unit into a Break team’s damage dealer at no pull cost.

Never Forget Her Flame tops the light cone ranking for The Dahlia at S1, ahead of Long Road Leads Home, Lies Dance on the Breeze and Resolution Shines As Pearls of Sweat. That order is prydwen.gg's, measured in play and rephrased here; every row of it sits under Light cones below.

When entering combat, The Dahlia regenerates 35 Energy and becomes "Dance Partners" along with the teammate that triggered combat. Whenever there is no other "Dance Partner" on the field, this unit and the teammate with the highest Break Effect become "Dance Partners" together. After a "Dance Partner" attacks a Weakness Broken enemy target, the Toughness Reduction from this attack will be converted into 1 instance of Super Break DMG at 60%. After an enemy target gets attacked by the other "Dance Partner," The Dahlia launches Follow-Up ATK and deals 5 instance(s) of DMG, each dealing Fire DMG equal to 30% of The Dahlia's ATK to one random enemy. After each instance of DMG dealt to a Weakness Broken enemy target, the Toughness Reduction from this DMG will be converted into 1 instance of Super Break DMG at 200%. This effect can only trigger once per turn. If the target is defeated before the Follow-Up ATK is used, it will be launched at one random enemy instead.

After using Technique, creates a Special Dimension that lasts for 20 second(s). Enemies within this dimension will not actively attack ally targets. After entering combat with enemies in the Special Dimension, The Dahlia immediately deploys her Skill's Zone, and converts the combat-triggering Toughness Reduction into 1 instance of Super Break DMG at 60% against enemy targets that are Weakness Broken. Only 1 Dimension Effect created by allies can exist at the same time.
When entering combat, increases other characters' Break Effect by an amount equal to 24% of The Dahlia's Break Effect plus 50%, lasting for 1 turn(s). When The Dahlia receives healing or a Shield provided by a teammate, this effect triggers again, lasting for 3 turn(s). Cannot trigger repeatedly within one turn.

When an ally target adds Weakness to an enemy target, increases SPD by 30% for 2 turn(s).
