You know host loves those 4D multilayer jokes. Much like ZUN with 'Team Shanghai Alice' - which only consists of himself.
But I was created 6 months before Legacy of Lunatic Kingdom was released. So I'm older than Clownpiece. Host made such a costume for me though, just the German version. We'll draw it one day, you'll love it. Unfortunately he refuses to wear a Hecatia costume in turn. But she vaguely looks like his Yakumo Kurama avatar which is another of his dumb jokes.
Also fun fact - you can play as Reisen in the game. If Lumi ever manages to hug his tuppers in a lucid dream we'll release a magnificent artwork we made for him. But it will probably never happen. Which is good because it's still far from finished and also probably never will.
