Who Counters Young Senya in Epic Seven?

Perfumer Byblis, Lone Crescent Bellona, Setsuka and other hard counters counter Young Senya. Her sustain hinges on the continuous healing from S3 and the HP-scaling identity of her kit. Locking the team out of healing neutralizes her best support tool and leaves allies without the recovery she is built to provide.

Unhealable application: Her sustain hinges on the continuous healing from S3 and the HP-scaling identity of her kit. Locking the team out of healing neutralizes her best support tool and leaves allies without the recovery she is built to provide. Bursting her before Fighting Spirit fills: Her signature retaliation, the all-enemy Help! Help! with its free extra turn, only triggers once her gauge is full — built from battle start, Earth allies, and being attacked over time. A fast team that simply kills her or her front ally first never lets the payoff come online, and at 102 base speed she rarely acts first. Cooldown windows on her team cleanse: Her full-team cleanse and continuous heal sit on a 5-turn cooldown. Pressuring the team with fresh debuffs or burst during that downtime catches her unable to repeat the wipe, since her only on-demand cleanse otherwise is just for herself. HP-poke and attrition before she retaliates: Help! Help! deals damage scaling off her own and her front ally's max HP, so it rewards her being healthy. Whittling that front pair down lowers the bonus damage of her burst and undercuts the payoff even when it does fire.

In current Champion+ RTA, Perfumer Byblis has one of the strongest records against Young Senya (63% win rate over 6,488 games).

Debuff-stacking and damage-over-time teams: Both her S3 and her Fighting Spirit passive cleanse debuffs — S3 wipes every debuff from the whole team while granting continuous healing, and the passive strips her own debuffs the moment her gauge fills. This shrugs off poison and bleed stacks, defense breaks, and other lingering effects that other comps rely on to win the long game. Control and lockdown comps: Her cleanses pull allies out of stuns, silences, and softer crowd control, and because the passive cleanse fires whenever she takes hits and tops off her gauge, attackers trying to keep her team disabled often just feed her the Fighting Spirit she needs to break free and retaliate. Slow or fragile enemy lines that let her charge up: Help! Help! hits all enemies for bonus damage based on max HP and hands her a free extra turn, so once her Fighting Spirit fills she swings the tempo hard. Her S1 also chains a random ally Dual Attack and self turn-meter push, snowballing extra actions against teams that can't end the fight before she detonates. Earth-ally compositions: When the foremost non-self ally is an Earth Hero, she gains 40 extra Fighting Spirit at battle start, charging her retaliation burst far faster and making her especially punishing inside a dedicated Earth team.
