Miss Chrom is the executive of the crime syndicate 'Reservoir Snakes'.
Miss Chrom joined the 'Reservoir Snakes' only a few years ago. It was when the syndicate was competing with others to expand their powers within the Rah Empire. At the time, Miss Chrom was a grunt of a rival gang of the 'Reservoir Snakes'. One day, she contacted the 'Reservoir Snakes' and made them an offer. If they wanted the Rah Empire, make her an executive. The syndicate's other members al claimed she was a mole and suggested taking her out. However, the boss 'Great Grandma' was intrigued by Miss Chrom's boldness. The Great Grandma gave her a one-year opportunity, under the condition a single failure would result in her death.
Miss Chrom joined the 'Reservoir Snakes' and immediately expanded the syndicate's business. Not just weapons smuggling, but instigations, interferences, and assassinations. No matter how dirty the job, it would be done if the price was right. Thereafter, Miss Chrom contacted the Rah Empire's powerful individuals such as the wealthy, nobility and imperial families. Even those who were weary at first soon became charmed by Miss Chrom's silver tongue, and in no time jobs for the syndicate grew. As the syndicate's influence over the empire continued to grow, Miss Chrom started to eliminate competitors. A few resisted, but they were no match against the 'Reservoir Snakes' which had already formed a tight relationship with the Rah Empire's corrupt power class. Miss Chrom turned the 'Reservoir Snakes' into the largest secret syndicate in the Rah Empire within 1 year.
Having been recognized by 'the Great Grandma' for her remarkable performance at the empire, Miss Chrom was entitled as the ninth executive of Reservoir Snakes. As if she waited for this precise moment, Miss Chrom immediately began to get rid of the nuisances scattered within the organization. The most famous episode related to Miss Chrom, is where she once turned the affair of being exposed for weapon smuggling into receiving a medal of honor for services of public security. It is told that even the Great Grandma grinned with satisfaction. Acknowledged for her contributions from then on, she was put in charge of coordinating the syndicate's tactics.
Miss Chrom feels extreme pleasure and satisfaction when her carefully laid plans fall perfectly into place without error. On the other hand, her plans going awry is her biggest disdain. She eliminates anyone who messes up her plan with unpredictable behavior regardless of whether they are friend or foe. Indeed, the death toll of disobeying orders is higher than that of syndicate operations. Due to this fact, the agenda that Miss Chrom should be submitted to disciplinary action arose within the syndicate. However, as the number of members executed for disobedience has been proved to be lower than the expected casualties for the operation, such opinion has been put to rest.
Miss Chrom isn't satisfied just being No. 9. Reservoir Snakes is just a stepping stone for her to reach even greater heights. She considers Arabelle and others loyal to the Great Grandma as mere pawns for her to manipulate. She already tracked down Elvira, but she is keeping her location a secret from the syndicate's future plans. Miss Chrom acts as an executive of Reservoir Snakes. However she is willing to work with anyone to achieve her grand scheme. Even if that anyone is the organization's target.
