DMM.com has revealed that Ikumi Hasegawa is joining the cast of the TV anime adaptation of Tadatoshi Fujimaki’s KILL BLUE manga series. Hasegawa will be playing the role of Mermaid Queen Mai Otohime in KILL BLUE, and a new key visual was released.
Hasegawa commented on her role: “She’s a marine sports prodigy. I grew up in a landlocked prefecture and have never tried marine sports myself, but earlier this year I felt strangely drawn to go see the ocean by myself one day. Maybe Otohime was calling out to me… or maybe I was just exhausted. Otohime is a girl with two different sides to her: “Chibi-hime” and “Gyaru-hime.” It was so much fun getting to play two completely different personalities! Please look forward to seeing how Otohime gets tangled up with Juzo and the others!”
