Story

Story I

Cherry blossoms filled the Shiranui dojo, but there was no poetry in Mai Shiranui's childhood. As the clan's brightest hope, she was raised on sweat and steel. While others tended flowers, she mastered flames and fans, deadly beauty with a whisper.

Story II 🔒 1★

When she stepped into the arena, the air shimmered with heat. Her swaying stance wasn’t just a dance, it was deception. Entranced by her beauty, opponents never saw the Ryuuenbu that sealed their fate. She proved beauty can kill.

Story III 🔒 2★

Beyond her mastery of ninjutsu, Mai Shiranui is refreshingly straightforward and somewhat romantic. Her pursuit of her beloved leads to bold, impulsive acts, like appearing in a wedding dress to encourage a proposal. She stands in bright contrast to the brutal fighting world. No matter the trials, her devotion never wavers.

Story IV 🔒 3★

As the Clone Legion casts a shadow over the Isle of the Banished, she makes her stand. She joins her allies without hesitation. In the name of Shiranui, she becomes a blade against the darkness. Witness it, when her fan flashes, all is consumed by flame.
