Cast Comments

Murayama Ayaki (playing Momo)

“I’m so happy to have the chance to play Momo in the Dandadan stage. This is my first time on a 2.5D stage, and I’m excited but also watching carefully to see how the chaotic world of Dandadan can be brought to life on stage. I’ll do my best to make Momo — strong, cool, and beloved by everyone — truly live on stage. See you at the theater!”

Ninomiya Remu (playing Okarun)

“Congratulations on Dandadan’s 5th anniversary! I’m so happy to be playing Okarun in this special year — and to be on stage myself for the very first time. As Okarun, whether the topic is aliens or ghosts or monsters, I’ll do my best to bring out the full power of Dandadan on stage. Please come and experience the thrills at the theater together!”

Momona Hiroki (playing transformed Okarun)

“I’ll be playing the cursed version of Okarun — Okarun in full possession mode. That form alone makes it special, and every feeling I had to suppress during those moments in the story hits so vividly. I’ll practice hard from the start, making sure I don’t fall behind Dandadan’s speed, and I’ll deliver the fire that only the stage can give — so please watch!”
