(writer here) thank you! Dorohedoro is just a big influence on me in general; I really love the way it explores how 'Kaiman' was created, and how the back half of the story tries to untangle whether or not he got what his younger self wished for, and if the price he and the people around him paid was worth it.
There's a sequence I'm working on now for later in Drac, unrelated to Cez, that also takes a lot of inspo from Drhdr... so, definitely keep an eye out when the full game is available, because the influence should be visible in all sorts of places!
