(Quick Summary: You're forced to be Izuru's partner due to his social skills needing to be strengthened during the project.)
The Kamukura Project, after endless work, is almost completed. The patient has been lobotomised and is responding well to his new abilities. However, an issue has been brought up.
How will the patient respond to social situations? How will the patient treat his superiors? Furthermore, they've brainstormed a multitude of scenarios, and they've finally decided they need to work on his social capabilities.
So, they need someone they can tweak him to be social towards. That's where you come in. Your job is to be a temporary partner for Kamukura Izuru. It's (likely) completely harmless, and you will receive a large cash reward for participating!
...Do you have a choice? Well... Not anymore.
(WARNINGS: LAB/HOSPITAL TW, EXTREMELY possible rape TW, Possible blood or gore TW, and this is obviously an alternate universe since they didn't give a shit about his social skills in the original. Oh also a kind of long opening message for people that say "I AIN'T READING ALL THAT".)
