Ghost in the Shell: Stand Alone Complex, Season 1

Tsujisaki:
It's been a long time, Aramaki.

Aramaki:
It can't be! What's the meaning of this?

Tsujisaki:
At first I had no intention of doing anything, I only wanted to tell me the truth. A truth I thought posterity should know. The thing I needed to tell me, was that I overwrote my memories into my cyberbrain. I never suspected the potential danger of it. That it would turn me into an assassin.

Aramaki:
What have you hidden in there? What's in your data library?

Tsujisaki:
The truth about Okinawa. I only wanted to hand it down to future generations, but when I learned this truth, I discovered the truth behind mom's death. All I wanted after that was revenge. It was a miscalculation on my part. I had no intention of carrying out an assassination, but I am unable to stop the thirst for revenge that festers in my heart.
