Akekuri

endgame support

supportsp_generatorbuffer

Akekuri earns A tier as a reliable SP battery and party buffer. Her stagger-triggered Combo Skill and Ultimate restore SP efficiently, and she applies Heat Infliction plus Link to boost allied damage, though her personal damage is limited.

This endgame build transforms Akekuri into a dedicated support that constantly feeds the party SP and amplifies damage. The Frontiers set shortens her Combo Skill cooldown and rewards every SP recovery with a 16% team DMG buff, while Thermite Cutter adds an ATK buff after SP restoration. With high Intellect and Ultimate Gain, she cycles between Flash and Dash and SQUAD! ON ME! to keep the team's energy flowing, and the Redeemer Seal off-piece ensures her Ultimate comes back quickly for more Link uptime. This build is ideal for team comps that rely on expensive Ultimates and burst rotations.

Insights

Core Mechanics

Akekuri restores party SP through Flash and Dash, her Combo Skill that triggers whenever an enemy is staggered or hits a Stagger Node, and through her Ultimate SQUAD! ON ME!, which fires three Rallying Flares.
Her Battle Skill Burst of Passion applies Heat Infliction to an enemy, enabling Heat-related team reactions.
With the Staying in the Zone talent, her Ultimate also grants Link, which increases the damage of the next Battle Skill or Ultimate used by allies.

Scaling

Her SP recovery scales with Intellect through the Cheer of Victory talent, gaining up to 50-75% bonus recovery at higher talent levels.
Support uptime improves with Ultimate Gain Efficiency and Combo Skill cooldown reduction; ATK and damage multipliers are less important since she is not built as a damage dealer.
Team synergy matters more than personal stats; she wants frequent stagger procs and party compositions that can feed her SP loop.

Team Role

Akekuri is a flex support and offensive enabler who slots into nearly any team as a SP generator. She doesn't need to be the main carry; instead she rotates in, applies Heat Infliction with Battle Skill, staggers enemies to trigger Flash and Dash for SP, and fires her Ultimate to restore SP and grant Link to buff the team's next burst. She works especially well in teams that need SP acceleration for high-cost Ultimates, and can also support Heat or Electric-centric compositions if using OBJ Edge of Lightness. Position her near enemies to land staggers, and invest in Intellect and Ultimate Gain to maximize her support output.

Explanation

Thermite Cutter is chosen because Akekuri constantly restores SP via Combo Skill and Ultimate, letting the weapon's ATK buff trigger frequently for the whole party.

Frontiers set's CD reduction lets Flash and Dash come up more often, and the DMG buff after SP restoration rewards the same actions she already performs.

Redeemer Seal is used as an off-piece to improve Ultimate Gain Efficiency, so she can use her Ultimate more often and deliver more SP and Link buffs.

If you lack Frontiers or Thermite Cutter, early Catastrophe gear and free weapons are acceptable until the endgame set is assembled.

Notes

Frontiers set gives +15% Combo Skill CD reduction and a 16% team DMG buff for 15s after SP recovery, which pairs perfectly with Akekuri's SP loop.
Thermite Cutter adds a party ATK buff after restoring SP, making Akekuri a stronger offensive support.
Use OBJ Edge of Lightness when the team is centered on Heat or Electric; Fortmaker is a fallback if you want faster Ultimates but lose team buffs.
