Ulti creates a jellyfish that accumulates a charge in proportion to the chaos damage your team causes. Skill makes her spin shooting ribbons of chaos damage.
Her support skill also causes a burst and brings her back to the field, encouraging a playstyle to switch Operatives as needed like with Riptide.
Basically she works like Blue Archive's Wakamo, that you want to make most of what you can of the period the enemies are under the effect of her ulti to repeat all the damage dealt.
