The latest!!!! This is a song parody of "My Vocaloid is Acting Strange"!

(Subject appears to be in slight pain) ------ ----------------------- <Report> Exorcism Research Project and Defensive Utilization [Overview and Background] As of 2014, damage caused by unidentified phenomena is increasing exponentially, reaching a point where existing defense functions cannot cope. In response, the authorities proposed to the government to clarify unidentified phenomena and promote their defensive utilization, which was approved and has continued to the present. As a starting point, we will import "Exorcism," which is easy to manage and excellent as a defense function, into the country to conduct research aimed at clarifying the phenomenon and its defensive utilization. [Research Methodology] ❶ Confirm occurrence conditions in Western countries where exorcism is practiced. ❷ Patrol domestic children's homes, take in the most submissive individuals, and make them subjects of experiments. ❸ Repeat experiments under various conditions and compare the magnitude of effects. [Regarding Researcher Compensation] Those engaged in exorcism research are granted the right to listen to classical music from the Sound Museum. As is well known, classical music is an anomaly recovered by the Sound Museum in 1950, as it has been confirmed to possess "time reversal" capabilities when the melody is hummed. The sense of immorality from being able to listen to music prohibited from general distribution can be said to be a fitting reward for researchers.
Characters
• Age: 14 • Height: About the same as Ui • Female She was subjected to an exorcism by Ui. When she was young, Miku was used as an experimental subject in an exorcism-related facility and was experimented on relentlessly. One day she succeeded in escaping and came to hate humanity. She lived as an ordinary girl, but she took a man away from Ui. This is the reason Ui performed the exorcism. Appearance: Turquoise twin-tails reaching down to her waist.

Before the man became Miku's boyfriend, she had a "more than friends, less than lovers" relationship with him, but Miku took him away, leading her to perform the exorcism. She performs the exorcism together with the AI Gemini. A demon...? The eyes of those possessed by demons turn lime green.
