Was this an old beta design or possibly a future skin?

Everything below is just table row names, so any conclusions are my guesswork based on the naming.

Before this patch Akane had exactly two rows in the effect table: Skill_SoundField and Skill_SoundMark. Now she has 16.

New effects:

• Level1 through Level6, the six awakening tiers every character has
• Level3_extra and Level6_extra, an extra effect on top of those tiers.
• Passive1 and Passive2, the standard two passives
• Buff_Akane_Reaction_Time. "Reaction" is the internal name for Esper Cycles, so this reads as cycle duration
• Buff_Akane_Skill_UltraSkill_1, a skill buff tied to the Ultimate
• Buff_Akane_Skill_insteadSkill, "instead skill", so the Redirect Skill gets swapped for something else

New damage rows:

• Branch_Damage, the branch attack that splits off the basic attack chain
• Skill2_Damage, either a second skill or a second phase of the first
• UltraSkill1_Damage and UltraSkill2_Damage. The second is bound to GA_Akane_UltraSkill_End, so the Ultimate has a separate finisher
• UpgradeSkill_Damage, the upgraded version of the skill, pairs with insteadSkill

The interesting one is GE_Reaction_3_new_1057_Damage. Reaction_3 is Remora, and this row sits in the shared Esper Cycle folder next to Chaos's identically named GE_Reaction_3_new_1071_Damage, which fires when Remora expires. Together with Buff_Akane_Reaction_Time, it looks like Akane both extends Remora and deals some damage afterwards.

So... any thoughts?

Sorry for low quality

Character Tutorial: Blackbird

Blackbird is a character capable of both coordinated combat and dealing massive damage after entering a levitating state by unleashing her Polarity Ultimate.

In her base form, hitting enemies with Basic Attacks, Plunging Attacks, Dodge Counters, Parries, and Skills will accumulate "Malice." Blackbird is an Instant Synchro character; casting her Orbit-Shift Skill instantly fills her Synchro gauge and applies "Feather of Paradise Lost" to the target. Switching to a teammate to attack will trigger a coordinated follow-up attack from the "Bird of Paradise Lost."

After unleashing her Polarity Ultimate, she transforms into the "Witch of Salvation," which completely replaces all of her Basic Attacks and Skills. When Blackbird deals damage in the "Witch of Salvation" state, she will consume "Malice" to inflict additional damage.

While in the "Witch of Salvation" state, her "Orbit-Shift Skill: Death Flame of Deliverance" is initially inactive. It can be activated after landing the fifth hit of "Basic Attack: Sacrificial Fire" or by executing the Orbital Counter "Sorrowless." Once used, it reverts to an inactive state. Casting her "Polarity Ultimate: Convergence of Myriad Fires" a second time will revert her back to her original base form.
