pleaseGoing from the automatic translation on Twitter, it looks like they're doing an animated commercial (PV is short for "Promotional Video" for the starter set with each of the pre-gens that are included in the box. The thread has the character designs for each of the characters and their voice actors - subsequent posts have messages from the actors (basically along the lines of "I'm glad to be a part of this project!")
Cast members are:
Sho FUJISAWA (No major credits) as Marshcarrot (Halfling Rogue)
Ichitarō KaI (Vtuber) as Dion Galax (Human Paladin)
Rina KAWAGUCHI (Record of Ragnarok) as Morgano (Dwarven Cleric)
Nobunaga SHIMAZAKI (Fruits Basket, Fate/Grand Order, Grimgar Ashes and Illusions, et. al.) as Ray (Elven Fighter)
Yoko Hikasa (K-On, New Game, Berserk 2016, Violet Evergarden, et. al.) as Alyssa (Elven Wizard)
someone link the video when it comes out
