Q: Is the demonspawn (Raze/Seer) romanceable?

Raze/Seer is not romanceable in this game, but he is a romantic option in two previous games: Demonheart and Demonheart: Hunters. I encourage you to check those out if you haven't already.

Additionally, there is a variety of Demonheart fanfiction available here. There has also been a nice amount of fanart over the years. Some of it can be found on the games' official Discord, or by searching on Tumblr or Twitter.

Q: Why is "the only attractive character", the demonspawn, not romanceable in The Cursed Trial?

In this game, he serves the role of an antagonist.

I am a human writer and not a content machine - when I force myself to write something I'm not inspired for, it shows. Writing another romance with the demonspawn in this particular game likely wouldn't have met your expectations.

This time, I wanted to explore a drama involving some human/demonheart characters. I hope you'll find the story compelling for what it is.

Q: How dare you put the demonspawn on the game's cover image if he's not a love interest?

Because he looks attractive, and he also makes it easy to recognize this is a game in the Demonheart universe. I hope you will click on him, check out what the game is about, believe the reviews and give it a try. (The game may have more reviews on Steam.)

The description indicates that the love interests are Ran and Kaisar. While you can flirt with the demonspawn, it's not a central part of the story but rather included as fanservice.

The Cursed Trial is a game that needs to be experienced - I can't tell you why it's good. I also can't convince you that you'll end up liking Kaisar, but many players do. Most of them did not expect it based on art alone, but they liked him after playing the first chapter. Your taste may differ, and that's okay. Just remember I am human, and this story is a work that I put my heart and soul into and it couldn't be something else.
