Since Demon Slayer rpg3 or Hinokami is the first demon slayer game to have sub classes I came up with a bunch of ideas and much more based off the anime and my own intuition
Demon SubClass/Special Ability:
- Selfless state this is a subclass which the player can trigger to get enhanced physical strength and dexterity but in the cost of ones defensive capability meaning it's a do or die type of ability.
- Order of the endless hunt which is a primary ability which makes a demons faster and stronger for a brief moment the more damage they take making it more of a passive that an entire ability
- Purity of the domain this ability makes it to where demons can get rid of status effect from stuff such and poison wisteria and butterfly breathing natural poison freeze burn all that.
Y'all can make more suggestions to these
Now for demon slayers - Monks known for their gentle appearance and tender affiliates but when pissed off these combatants take fights to a whole other level making fights monks have sacred beads on their hands which acts like a chain making for good combos and chain reaction.
- Ninjas known for their speed and stealth these character archetype are known to have a sort of resistance to demon scent making NPC demons have less agro at that player for exchange having less health than others.
- Dual wielders known for using guns and swords and know for their versatility in long range and short range in contrast they may/may not be able to ever learn a breathing style
4.Blood hunters known for their weird way of fighting usually involving sneakily killing their opponent and also having a strange ability to eat demons this subclass has a grab move tearing off the flesh of demons and having different chances or either copying the demons stats or one of its skills.
Y'all that's all for now y'all can leave more suggestions and I will keep cooking over and out
