That is sexual objectification, throwing in random bits of sexual gratification with no justification through characterization, and it isn't just wrong, it's fucking lazy.
"The House of Valentine was once one of the most wealthy families in London. Isabella 'Ivy' Valentine had been raised with love by her parents. However, her father, Earl Valentine, was driven insane by his pursuit for what was called the "Key to Eternal Youth." By the time of his death, his efforts to search for immortality had drained his family's fortunes and left one of London's most distinguished families in ruins. As if to pursue her husband into death, the Countess fell ill and passed away soon after Earl Valentine's death. This left Ivy as the sole surviving member of the Valentine family.
In reality, Ivy was not a true Valentine by birth. The Earl and Countess found her abandoned in front of their mansion when she was an infant, and she was taken into the family as an adopted child. Ivy discovered this secret only after reading a will left behind by the Countess in her death. But this did not matter to her, for the Valentines were the only parents she knew.
Searching through her parents' possessions, Ivy found her father's diary. In it, she discovered that the "Key to Eternal Youth" her father had been pursuing was a sword called Soul Edge. He had also been obsessed with the art of alchemy. To honor her father, Ivy chose to become an alchemist and investigate Soul Edge.
During this investigation, she uncovered the true nature of the sword?it was an evil blade that feasted on souls. Vercci, Adams, Captain Cervantes; the more she read of the fates of those who had come into contact with Soul Edge, the more she became convinced of her suspicions.
"My father was driven mad by such a loathsome thing...this evil sword!"
Filled with rage and despair, Ivy vowed to avenge the death of her father by using all of her knowledge to destroy Soul Edge. Ivy realized she needed to create a weapon powerful enough to destroy Soul Edge. Her knowledge led her to successfully create a weapon capable of shifting back and forth from a whip to a sword. This weapon was merely mechanical though, and Ivy believed the only thing which could stand against a living weapon is another living weapon. She attempted to use alchemy and her own blood to give the sword life, but all attempts were unsuccessful.
Finding her alchemic skills useless, she turned to studying ancient sorcery. Every midnight, she would attempt summoning rituals, hoping to call upon a being who would grant her sword life. With every failed attempt, Ivy became more desperate and angry.
At last, one night, a large malformed arm emerged from her summoning circle. The arm, sensing her attachment to her weapon, proceeded to touch the whip sword. Ivy heard a soundless voice seemingly coming from the arm.
"I, Cross of the Pledge, shall confer upon thee the Point in the Escutcheon of Destruction - Dexter Purpure."
The ceremony came to an end and the mysterious being vanished. Under the moonlight, Ivy's sanity began to crack. She finally had the weapon she had sought to create; a living sword which would obey her every command. Calling her weapon the 'Ivy Blade', she set out on her journey to find and destroy Soul Edge."
