One of his most challenging roles in his career to date was Shoujo (Little Girl).
Having completed his lead role as "Makise" in the feature film Night's Tightrope (Shoujo) (2016), Mackenyu started to expand his acting opportunities in Hollywood with a lead role in the series ZAPS, Inc. (2017) and the supporting role of Ryoichi in Pacific Rim: Uprising (2018).
