Traits
Watery Vengeance. Hashihime can breathe both air and water and has advantage on Strength (Athletics) checks related to swimming or grappling while partially submerged.
Shapeshifter’s Guise (1/Day). As an action, Hashihime can transform to appear as a beautiful woman, a handsome man, or even a regular traveler. This illusion lasts until she ends it (no action required) or is reduced to 0 hit points. A creature that suspects her true nature can use its action to make a DC 14 Investigation check; on a success, it sees faint traces of horns or candlelight flickering about her head.
Innate Spellcasting. Hashihime’s spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). She can innately cast the following spells, requiring no material components:
At will: thaumaturgy (PHB, p. 282), minor illusion (PHB, p. 260), produce flame (PHB, p. 269) (the flame takes the form of candlelight or a torch-like glow)
3/day each: charm person (PHB, p. 221), disguise self (PHB, p. 233), suggestion (PHB, p. 279)
1/day each: fear (PHB, p. 239), fire shield (warm shield only) (PHB, p. 242), polymorph (self only) (PHB, p. 266)
(Adjust or replace certain spells to suit your campaign’s needs.)
Actions
Multiattack. Hashihime makes two attacks with her Iron Staff, or one Iron Staff attack and uses Torch Bite if available.
Iron Staff. Melee Weapon Attack: +7 to hit, reach 5 ft., one target.
Hit: 13 (2d6 + 4) bludgeoning damage. If the target is grappled by Hashihime, this attack deals an additional 7 (2d6) fire damage as the staff ignites briefly.
Torch Bite (Recharge 5-6). Hashihime clamps a flaming doubleended torch between her teeth and lunges. Melee Weapon Attack: +7 to hit, reach 5 ft., one target.
Hit: 14 (2d8 + 5) piercing damage plus 7 (2d6) fire damage. The target must succeed on a DC 15 Strength saving throw or be knocked prone as the blow stuns them.
Bonus Actions
Fury of Jealousy (1/Short or Long Rest). Hashihime focuses her rage on one creature she can see within 30 feet that she believes is “happy” or “content.” Until the start of her next turn:
She has advantage on attack rolls against that target.
The target has disadvantage on saving throws against her spells and abilities.
Reactions
Wrathful Reprisal. When Hashihime takes damage from a creature within 10 feet, she can unleash a wave of boiling water. The attacker must succeed on a DC 15 Dexterity saving throw or take 10 (3d6) fire damage (scalding steam) and be pushed up to 10 feet away.
Lair or Environmental Effects (Optional)
If you present Hashihime as a boss near her cursed river or bridge, consider adding:
Candlelit Bridge. The bridge grows enshrouded by flickering candlelight illusions, imposing disadvantage on ranged attacks across a 20-foot span.
River’s Fury. At initiative 20 (losing ties), roaring water surges beneath the bridge, forcing each non-fiendish creature on or near the bridge to succeed on a DC 14 Strength saving throw or be knocked prone by violent water jets.
Lore & Behavior
Once a scorned woman named Kunitoki, she drowned herself in hatred and foul rituals, culminating in her transformation into a demon.
She despises displays of affection or happiness. Seeing a joyful couple might trigger her Fury of Jealousy.
Legends claim famed sorcerer Abe no Seimei once repelled her assault, leaving her humiliated but alive.
On rare occasions, she begs forgiveness for her crimes, only to backslide into aggression the moment her anger flares.
Lore
Jealous female spirit haunting bridges, terrifying passers with vengeful rage.
Legends say that mukashi ‑ mukashi or long, long ago a tragic event unleashed a chain of misfortunes. A woman named Kunitoki discovered her husband had taken a lover. Driven by consuming jealousy, she spent seven days at a shrine, praying to the gods that they would turn her into a demon so she could destroy her rival and punish her faithless spouse. The gods answered her plea, declaring that if she truly wished to become a demon, she must carry a heart filled with rage, transform her appearance, and spend 21 days immersed in the waters of the Uji River.
Resolute in her desire, Kunitoki divided her hair into five sections—so they resembled horns—then painted her face and body bright red. She placed an overturned tripod on her head into which she fixed three burning pine torches, and clenched a dual‑ended torch between her teeth. Aflame with otherworldly fire, she raced to the Uji River. After 21 days of ritual immersion, she finally became a demon, thereafter known as the Bridge Princess of Uji.
