Notorious - Marionette

Decades ago, two talented dancer sisters rose to fame overnight. Shining like a meteor, they attracted a massive fan base and held a magnificent performance at the bustling Ballet Twins.
However, as the show neared its end, the Hollow Disaster struck, engulfing the Ballet Twins and plunging the sisters into eternal darkness. The news devastated countless people worldwide.
Today, most people can only catch glimpses of their soulful dance through scattered video and image materials.
Only a few know that when the forgotten dance music echoes within the Ballet Twins, the ethereal figures of the Twin Marionettes emerge. These figures are believed to be connected to the Twin Dancers from that fateful performance, attempting to finish the grand finale they were never able to complete.
"When that eerie tune came to an end, the two Marionettes emerged from the darkness and curtseyed..."
"Huh? So... they're trying to say the show has begun?"
"No, I think what they're trying to say is... It's too late to run. It's over."

In combat, Notorious - Marionette will summon her dance partner to attack. Every time her dance partner is defeated, her next Stun's duration will be increased.
