Marie from Persona 4 Golden joins Adachi as a downloadable playable character for Persona 4 Arena Ultimax. For the first week after the fighting game launches in North America, Marie will be free to download. Afterwards, Marie like Adachi will be paid DLC.
Marie has Kaguya as her Persona and uses skills that immobilize opponents. Take a look at this video to see what the Tsundere Poet of the Hollow Forest can do.
