Riot Games initially teased the Japan server at Tokyo Game Show 2015, and although no confirmed launch schedule is available, the developer released a “behind the scenes” teaser for the voiceover work. In the video, Uesaka Sumire (Overlord) was confirmed as Jinx, Fujiwara Keiji as Master Yi, Hanae Natsuki (Aldnoah.Zero) as Ziggs, and Yuuki Aoi (Seraph of the End) as Lulu.
