A very fast Rupture identity that gets Haste from her counter and reaches 10 speed on turn two. Her Gluttony counter keeps her Rupture count neutral and gives her Strider, so her speed-based coin reuses and extra damage trigger reliably. She is the weaker of the two Mao Branch identities, but still excellent for bursting down a single boss, and she is free from the event shop.
How to play
Use her counter whenever you lack Strider and are not planning skill 3, since it gives three Strider, extends the Gluttony chain and is Rupture count neutral. Aim to use skill 3 by turn two once she is at 10 speed, ideally as an unopposed attack, for Deathrite Haste, extra count and the big last-coin roll. Skill 2 is count positive and tops up Haste. Be careful with skill 1, which can ruin your stack in a bad rotation. She is frail, so never let her get hit if you can avoid it.
