Demon roses are divided in three types:
- the Royal Demon Roses, which have a potent poison, which may easily kill almost anyone who touches its thorns;
- the Piranha Roses, which may eat away anything that touches its thorns and;
- the Bloody Roses, which may absorb liquids in an amazing speed.
The royal demon roses also cause blood poisoning at long-time exposions, which renders the Pisces Saint a poisonous blood.
