In the episode "Heal the Pain" of the anime series Witch Hunter Robin, we see the members of the STN-J working on a mission to investigate a series of murders that have been happening in the city. The murderers are all former patients of a particular hospital in the area, and it seems that they have all been driven to commit these heinous crimes due to a mysterious drug called "Arsenotheca."

The STN-J agents, led by Robin, work tirelessly to uncover the truth behind this drug and how it is connected to the murders. As they delve deeper into the case, they discover that the drug is being used to enhance the psychic abilities of its users, making them more powerful but also driving them insane in the process.

Through their investigation, the team also meets a former doctor at the hospital who has been working to create a cure for the effects of Arsenotheca. However, he is met with resistance from both the hospital administration and the patients themselves, who see the drug as a way to enhance their own abilities and are unwilling to give it up.

As the STN-J agents race against time to stop the spread of Arsenotheca and the murders it is causing, they also confront their own beliefs and morals about the use of supernatural abilities. In the end, they must make difficult decisions about how to handle the situation and whether or not to intervene in the lives of those affected by the drug.

With stunning animation and a gripping storyline, "Heal the Pain" is a captivating episode that explores themes of power, morality, and responsibility. Fans of the supernatural genre will surely enjoy this episode and the series as a whole.
