Her previous major roles were Ushio Kofune in Summer Time Rendering and Harley Quinn in Suicide Squad ISEKAI, and was also the voice of Riko Amanai in JUJUTSU KAISEN Season 2.
With the two additions, the voice cast of Takopi’s Original Sin includes:
- Reina Ueda as Shizuka
- Kurumi Mamiya as Takopi
- Konomi Kohara as Marina Kirarazaka (NEW)
- Anna Nagase as Naoki Azuma (NEW)
The two voice actresses both left comments on their roles:
Konomi Kohara (Marina):
As I read through the original story, my impression of it kept evolving. The narrative unfolds in a shocking way, and while Takopi is incredibly cute and healing, I also came to realize how central he is to the story.
Marina is a character who evokes a wide range of emotions the more you learn about her. I’m carefully holding on to each of those feelings as I bring her to life. I look forward to sharing this with everyone. Thank you!
Anna Nagase (Naoki)
I am honored to voice Naoki in Takopi’s Original Sin.
I still vividly remember reading the manga as it was serialized, trembling with anticipation at each new development. I never imagined I would one day be part of the anime adaptation—this is truly a privilege.
I want to approach Naoki’s heart with kindness and portray her with great care. Please look forward to the completed anime!

Background
Taizan 5 wrote and illustrated the Takopi’s Original Sin (Takopi no Genzai) manga. It was published on Shueisha’s Shonen Jump+ platform from December 2021 to March 2022, getting a total of 2 compiled volumes. VIZ Media licensed the manga in English, describing the story:
Cute little alien Takopi lands on Earth. What is his mission? To be taken to our leader? No. To spread happiness throughout the universe!
The first person Takopi meets is depressed fourth grader Shizuka. (Or is it…?) Takopi is determined to do whatever it takes to make Shizuka smile again. But his misguided attempts to help her by using his advanced technology to turn back time only result in mayhem and death.
What is the truth Takopi can’t remember? And what must the pink alien octopus with a heart of gold sacrifice to truly help Shizuka and her friends…?
The anime adaptation was first announced on December 9, 2025.
