Voice Casts

Anna Nagase (voice of Harley Quinn)

Character Description

Gotham City’s Mistress of Mayhem. A former psychiatrist and The Joker’s love interest who possesses exceptional agility and a sharp intellect. Her wild and unpredictable behavior wreaks havoc wherever she goes.


Hello! I’m Anna Nagase, voice of Harley Quinn.

Suicide Squad ISEKAI is happening for real!!!!!

I never believed I would be voicing a character as iconic as Harley Quinn.You never know what life has in store for you.

Harley Quinn is sweet and giddy and full of love for her puddin’ (The Joker). Everything she does is for her puddin’ and that doesn’t waver even when she lands herself in ISEKAI.

With all the tenderness and pure love in my heart, I will do my best to cause havoc with my acting! Please look forward to it!

Yuuichirou Umehara (voice of The Joker)

Character Description

Gotham City’s Clown Prince of Crime. He’s the most unpredictable Super-Villain who brings chaos and madness with his utterly deranged thinking. Harley affectionately calls him “Puddin’.”


I’m honored to be playing the role of The Joker, one of the most iconic Super-Villains in popular culture.

At first, I was worried about how to voice The Joker at first – a character that has been played by so many people, but there have been many different images of The Joker portrayed in many different works, so I decided to play the Joker as I saw fit this time. As a results, I really enjoyed the recording session in the end.

Before working on this anime, I watched movies such as “The Suicide Squad” and “The Dark Knight” trilogy. I have not been exposed to DC Comics’ works in the past, so it was a new experience for me and a chance to learn about a new world.

This anime is set in an alternative world or ISEKAI, a setting unique to today’s animation, and the villains who run amok as they please are a delightful sight to behold. I played the voice of The Joker in this world while keeping that in mind.

I hope you will enjoy the anime when it comes out.

Reigo Yamaguchi (voice of Deadshot)

Character Description

An expert marksman who never misses his target. Rough and foul-mouthed by nature, he sports a gauntlet on both arms.


I couldn’t find a voice nor think clearly for my mind went blank when I heard I was casted as the voice of Deadshot.

I am still a rookie in this industry, and I was very nervous to record the scenes surrounded by the star-studded voice actors. However, I remembered that Deadshot is a brave man who is always true to himself, so I went into the recording session with an open mind and without fear, just like him.

The passion and love of the creative staff visibly increased with each recording session. With that in mind, I put my everything as an actor on the line to do the best I possibly can.

Whether you are a fan of anime or DC films, Suicide Squad ISEKAI will sure snipe at your heart so please look forward to its release!

Takehito Koyasu (voice of Peacemaker)

Character Description

A hulking macho man and violent vigilante determined to achieve peace at all costs. He possesses a twisted sense of justice and considers himself a superhero.


Well well… Who could have imagined that “Suicide Squad” was coming to Japan in an anime style? Also, the central theme is “ISEKAI”!

Thunder-struck and earth-shattering…Two of the favorite genres united!

Happy! I am happy! I get to be part of it! My role is called “Peacemaker”, a violent vigilante who believes in achieving peace at any cost no matter how many people he has to kill for it in the process! Oh wait. He is a villain, right? Of course, he is the worst! That’s how the story of “Suicide Squad” should be!

So, leave your morals somewhere and enjoy their rampage into ISEKAI world! You can’t help but see it now!

Jun Fukuyama (voice of Clayface)

Character Description

A struggling movie actor and loquacious, chatty narcissist. A shape-changer made of living clay, he freely changes his appearance in battle.


I am ecstatic that I got this role. One thing I always keep in mind during the recording is “elegance”. I voiced him with elegance, but bold and powerful at the same time, with a pinch of humor.

We are working on this title with a strong cast and crew so that you get to enjoy a different take on ISEKAI, as much as the “Suicide Squad” members.

Subaru Kimura (voice of King Shark)

Character Description

A shark-like humanoid who has the IQ of a kindergartener. A pure and innocent soul, he is solely preoccupied with satisfying his appetite.


I was so happy that my Jaw(s) dropped!

I am a huge fan of the “Suicide Squad” that I went see the movie as soon as it came out in cinemas. I was especially a big fan of the rugged yet super cute King Shark, so I was happy to be chosen to play the role.

As King Shark is known for his unique speaking style, my script was filled with one syllable words and was hard to play the role with emotions. However, in the end my main aim was how to voice King Shark like the way he is, savage and sweet.

As a result, this is the lowest voice for Subaru Kimura. (Low, meaning the tone of the voice) I think the finished product is great! I strongly recommend watching this anime. Harley Quinn is cute!
