A couple of months ago, the J-List Blog posted an article announcing that the isekai light novel series that still doesn’t have an actual publishing deal in Japan, My One-Hit Kill Sister (Japanese title: Isekai One Turn Kill Nee-san: Ane Dōhan no Isekai Seikatsu Hajimemashita), would get an anime adaptation in 2023. At the time of that initial announcement, fans were treated to a few details, including the primary cast and crew. Unfortunately, they weren’t ready to show us any clips of the final product. That changed on Sunday, October 23rd, when the first promotional video got posted on YouTube.
Lasting a little under a minute, the first promotional video plays into the series’ action and drama (complete with tense battle music) rather than attempting to woo fans with any kind of silly antics. You have to respect that decision.
Along with this promotional video, My One-Hit Kill Sister also revealed additional cast members in the form of (character names first):
Tanya: Rio Tsuchiya
Sophie: Azumi Waki
Gloria: Sora Tokui
Kuon: Konomi Kohara
Siegfried: Yuma Uchida
My One-Hit Kill Sister has already set itself up to be a “proving ground” series as not only will it be the debut production of animation studio Gekkō, but it is also the full directorial debut for Hiroaki Takagi. Also, as previously reported, the scripts will be written by Yōhei Kashii while Yūji Hamada provides the character designs. Crunchyroll has already revealed their plans to simulcast the series whenever it premieres in 2023.
In this series, the main character is a high school student named Asahi Ikusaba (played by Yuki Sakakihara) who finds himself in a new fantasy world. The problem is that, despite having knowledge of video games from his previous world, in this new world he has no actual “cheat” skills or abilities of his own. Eventually, he finds his older sister Maya (played by Haruka Shiraishi) who happens to not only have the strongest “cheat” skill in the world but also a very strong brother complex.
