Set against the backdrop of Japan's rapidly modernizing Meiji period, Infiltration! Agent on the Edge follows the story of a desperate female spy forced into a corner. With her father's insurmountable debts hanging over her head, she accepts a perilous assignment from her demanding boss: infiltrate the illustrious Mikage commercial empire. Her objective is the "Contract Seal," a powerful artifact guarded within the family's heavily fortified estate. Disguised as a maid, she prepares for a life of stealth and deception, believing she is ready for anything the mission might throw at her.
However, the Mikage household holds secrets far stranger than she anticipated. Her infiltration is immediately complicated by the presence of Shidou Tsukiomi, an enigmatic figure who wanders the halls. To her shock, this handsome stranger is not a butler or a guard, but a man donning a maid's uniform with surprising ease. Is he a fellow spy, an eccentric family member, or a dangerous trap set to catch intruders?
As the protagonist struggles to locate the seal while maintaining her cover, she finds herself drawn into a tense game of cat and mouse with Shidou. Their encounters spark with a mix of suspicion and undeniable chemistry, blurring the lines between duty and desire. With her boss growing impatient and the threat of exposure looming, she must outwit a rival who knows the art of disguise just as well as she does. This historical romance combines espionage thrills with steamy tension, delivering a unique twist on the classic undercover agent trope.
