Actually it's more like a Kim DokJa and Yoo JoongHyuk's child...
It has not much of SJW
Quite contrary, I can't see much of KDJ's characteristics in Cain but a lot of Jinwoo's. Things like;
1. Unnecessarily OP as fuck
2. Cold, terrifyingly level-headed AND indifferent when dealing with enemies rather than the deceitful provocative smug bastard that Dokja is. It also contrasts with YJH's who is a hot-blooded character when dealing with enemies(like, I'm still facepalming and relates spiritually with KDJ about that Poseidon and Nirvana things, YJH.) Cain and SJW has the same level of absolute chill of #unbothered when dealing with enemies.
3. Same dere archetype. They're classic kuudere archetype. YJH is wildly been agreed as a tsundere. Idk what kind of dere Dokja is but he is probably a kamidere with a dash of (oblivious) sadodere.
4. Power over death/souls. Nuff said
5. Equally GREEDY cold-blooded bastards. Okay, maybe Cain has more dignity than Jinwoo since he didn't purposely let someone dies to gain power--wait nvm, he let the sabre tooth tiger died to evolve Chirpy; which on the same level of cold-blooded as SJW letting Kim Chul died to gain a soldier.
6. Female simps magnet. Sorry not sorry, Dokja but you ain't one in your own story lol. (But fret not you're the king of us fangirls' hearts)
this makes me see cain in a different light lol
He is very similar to Jinwoo, lord and savior of new gen fantasy manga's. TO620 had laid everything down for you so I can't say much more
Cuz she said that Cain is what it would be like if YJH and Sung Jin-Woo had a secret lovechild together and now I can't unsee that. Cain even got YJH's golden eyes and Jinwoo's horrible naming sense. And oh yeah, the general OP cheat too.
