Comment from Mamiya Kurumi
I first encountered “Tacopi’s Original Sin” while working on a voice comic.
There were so many shocking developments… I wanted to read the rest, but at the same time, I was constantly feeling anxious and excited.
Now that it’s being made into an anime, I’m constantly thinking, “I can’t believe it!”… I can’t believe I’ll get to play Tacopi again… I want to convey Tacopi’s words, those choices, and those feelings at that time. I want fans of the original manga and those who are watching the anime to see it through to the end.
It’s a work that I want you to see, feel, and talk about with your friends. Thank you very much!
Shizuka

Comment from Reina Ueda
Just seeing the key visual brought back all the memories of when I read the original work, and I couldn’t help but tremble at the thought of this work being made into an anime.
I will do my best to face Shizuka-chan without getting too attached to the overly cute Tacopi.
I hope you’ll enjoy “Tacopi’s Original Sin” in the anime as well!

As I read the original work, my impression of it changed significantly, and there are many scenes where Taco Pi is soothing and cute, and she holds the key to this story. The
The more I get to know Marina Misaka, the more emotions she is filled with, and I am playing her while cherishing every one of those feelings.

I’m Anna Nagase, and I will be the voice of Azuma in “Original Sin of Tacopi.”
I recall vividly that when the manga was being serialized, I would tremble as I turned the pages. I
I never thought I would appear in an anime… I’m honored.

Please look forward to the completed anime…!
