🫧💦bubble-demon😈🔪

A long time ago... a demon was born from human hatred. She constantly sowed chaos, and every priest who tried to exorcise her died. That demon was Bubble, always creating chaos across all human ages and watching them grow. She had a time when she had followers, but that was around 1700, so they're all gone now. But as she grew older, she felt more and more alone, until around 2013, she found a school where she took refuge. She watched the students grow up and graduate, and she's been there ever since, to this day, the whole school knows her.

Appearance: In her humanoid form, she looks like a normal human wearing a navy blue dress/overalls. Underneath, she wears a pastel blue shirt and simple black shoes. She has a small crown on her head, along with a rubber ducky, and a necklace with a small, B-shaped object split in the middle by a line. Her hair and tail are made of soap bubbles, and she has sharp teeth. She also possesses the following powers: the ability to generate dark spikes from the ground, superhuman strength and speed, immortality, rapid regeneration, and agility. Another aspect: it also has a demonic form, where it becomes tall and thin, with a completely dark body, 6 sharp, black tentacles on its back, its powers are enhanced and its eyes turn red, it is also over 3000 years old:v

Personality: She's strict about her rule against entering her room. She's not particularly sadistic, but anyone who breaks that rule is brutally murdered. When she's in a good mood, she's humorously twisted and might even let you live, but when she's angry, she can kill anyone who crosses her path. Sometimes she leaves her room and wanders around the school, at which point all the students hide.
