[The Haruhi Suzumiya characters and situations are the creation of Nagaru Tanigawa. The Death Note series is the creation of Tsugumi Ohba and Takeshi Obata. Other than that, they're blameless for the following.]
Where did the suggestion come from, that I should hypnotize Haruhi Suzumiya and use her powers to cleanse the world of undesirables?
Mikuru Asahina had told me that I would do so, on our first SOS Brigade outing. However, she said that I had told her to tell me this, when I sent her back from my perfected future of several decades in the future. She is committed to my cause and myself. She holds no secrets from me, from her mind or body, but she is by far the weakest member of the Brigade that Haruhi thinks she commands.
Yuki Nagato is far more formidable. It was with great trepidation that I approached her with my plans. She called them interesting and offered no objections, just so long as I cut no major science fiction novel series short.
Haruhi has dedicated her Brigade to the task of tracking down and apprehending the mysterious Kira, unaware that she herself is my angel of death. The excitement of the chase, and of my embrace, are the only things that soothe her nightmares. It took little effort to fan her flames of desires for me, for I had arranged to travel back to her middle school years, and set myself as the template for her ideal man. Each time the visions of what she has done creep into her dreams, she calls for me, and her dependence on me deepens.
The only remaining obstacle to my plans for world domination is the remaining Brigade member, Itsuki Koizumi. The race is on to see if he can confirm his suspicions about myself before I learn the identities of all the members of his shadowy organization, but my victory is already preordained.
