~Promise~(Chiyo) Wiki

Katsu! she has breasts! stare at them!

Katsu is the Goddess of Darkness and the older sister of Yume Like her sister, she was worshiped in ancient times, but nowadays she prefers to avoid human contact.

Her apperiance is parallel to her sister. She has short black hair, red eyes, skimpy black clothing and wears a red rose on the right side of her hair.


Katsu was the first thing to exist, and the creator of the ~Promise universe. After creating her sister in her image, the two created the world, and ruled in harmony. Until the spread of Chrisianity, then Kastu and her sister were referred to as "blasphemous pagan goddesses" and were completely forgotten.

Like her sister, Katsu has unimaginable strength. Katsu also has unbeatable range, as she can attack from any distance at any time. Her defenses are quite powerful as well, but can be easily destroyed with the right power.

Her weapons are unknown, since she mostly uses her power over Darkness when in combat, or just aggravated.

Exploding Lemonade[]

Katsu has appeared several times thoughout the story of Lemon Dreams, and has bailed her sister out, helped Hatter out, and fought in the Underground within her appearance.

Her most notable role was when she met up with Spirit sometime after Luna's gruesome demise, there the two argued, and Katsu began to feel remorse for her actions. After Spirit heard her past, and after Yume pointed out the similarities she and Spirit had, Katsu went for a walk, and encountered D-Struction trying to blow up the city. Despite her attempts to stop him, she was fatally wounded, and blacked out. The following morning, with her last ounces of strength, she abandoned her physical form, with her last words being "Help me, sister"

Her reasons for attacking DS were in order to save the humans; something that Katsu would never do.

3 weeks later, she came back to the sanctuary, only to find out that Yume had been killed, eaten, and fused with Spirit.

She then attempted to establish a relationship with Hatter, but lost her patience and killed him, before being captured, drained and disposed of by a man called "slash".
