Saori Onishi has been announced as a new voice cast member for the upcoming Magical Explorer TV anime series. The anime will premiere in Japan sometime in Fall 2026.
Onishi will voice the character Yukine Mizumori, who has been added in another updated teaser visual of the anime series, along with protagonist Kosuke Takioto and Ludie. She previously voiced Ais Wallenstein in the Is It Wrong to Try to Pick Up Girls in a Dungeon? anime series.
Onishi joins a previously announced voice cast that include Nobunaga Shimazaki as Kosuke Takioto and Ai Kakuma as Ludie.
Kazuki Ohashi is directing the anime series, with Satoko Sekine (Mysteria Friends) as series composer, Ryosuke Kimiya as character designer, and Kenichiro Suehiro (Re:ZERO -Starting Life in Another World-) as music composer. WHITE FOX is in charge of the animation production.
The isekai fantasy light novel series is written by Irisu and illustrated by Noboru Kannatsuki. It was first published under Kadokawa’s Sneaker Bunko imprint on November 1, 2019 and has released 13 volumes as of April 2026. The series started as a Shosetsuka ni Naro web novel in February 2018.
A manga adaptation illustrated by Yukari Higa was launched in August 2020.
Yen Press releases the light novels and manga series in English under the title Magical Explorer: Reborn as a Side Character in a Fantasy Dating Sim. It describes the main synopsis of the light novel series as:
Few titles are more revered among horndogs-(ahem) connoisseurs of Japanese erotic video games-than Magical Explorer. One day, our smut-loving hero wakes up to find he has been reincarnated into the body of the game’s dreamboat protagonist! Or rather, his hapless comic-relief best friend, Kousuke Takioto. But with his unparalleled knowledge of Magical Explorer and Kousuke’s unorthodox abilities (a scarf that doubles as a fist?), our hero vows to turn the game’s unluckiest loser into its mightiest heartthrob. In this world, nothing is out of reach when you’ve got the know-how!
