Marilyn.

At first, Marilyn appears to be sweet, playful, seductive and cheerful. In reality, due to her tragic past and her work as an assassin, she is in fact ruthless, aggressive and cunning, yet sad on the inside. Her ego after becoming a leader ends up getting bigger. Despite this and her wealth as she becomes a leader, she is not entirely greedy about money nor doesn't care about violence, but solely desires to rule the world beyond Black Hand under her rule, as well as her past respect towards her adoptive grandfather.

Past life: She was born in a rural village at Hebei province. Unfortunately, being considered as a Heihaizi (bastard child in Chinese) who was raised in the family that she has been neglected and ignored, conceived outside from the One Child Policy, until an Old Farmer adopts her for 100 yuan, and revealing his past history to her. Fascinated by her adoptive grandfather's past as a Piguaquan master, she begins to help his farm work, in order to work out her body, and earns enough money to buy an iron sandbag, filled with iron grains and mung beans to train.

Unfortunately, some years after her grandfather tragically passed away from sudden illness, she became orphan again, abandoned her birth name, and calls herself "Marilyn Sue" to find jobs in the spring in Shanghai for her survival and likely to find a way to honor her adoptive grandfather's wish. Upon being accused of touching customer's money while working for Mizu-shōbai, she nearly killed the customer and the hostess. As she was running soaked and wet in the rain to alleyway one of the members of Black Hand mafia organization found and capture her. However, she was welcomed and admires by her boss, Yin Hu for her lethal tactics, and not out of sympathy for her being a orphan and she wanted money for something in her previous job. She and her fellow member, Wei Ye Lue became the mafia's top assassins and one of the future leading candidates for years up to 266X AD-IJ/200X AD-GR, though both assassins didn't go along each other.

Akatsuki Blitzkampf (Ausf. Achse)/Enchanted Princess: Growing tired of her boss' incompetence, Marilyn met Mycale (who was possessing Kati's body). Blinded by ambition to overthrow her boss, Marilyn formed an alliance with Mycale, and killed him by her own hand. This led Wei, who witnessed her murdering their boss, to begin to hunt her down in revenge.

By the time Mycale (as a messenger) inform her the existence of the Blitz Motor and the revival of it's first successful super-soldier of World War II, Akatsuki, she began to hunt and kill or defeat him then take his Blitz Motor from him to become a new leader of the traid. However, she is now in pursuit by her former Black Hand ally, Wei.

Despite being deceived by both Mycale and Murakumo, Marilyn ends up leading Black Hand by luck, thanks to the large amounts of gold she obtained to bribe the mafia's higher-up to ascend her leadership. However, every time suspicions about her predecessor's assassination were raised she had to spend all of her time purging the internal conflict.
