Jax and Remember

Remember, this is a stylized jester girl. She has completely white skin and skinny limbs. Her main distinguishing feature is her asymmetrical pupils, shaped like red and blue rotating spirals. She is dressed in a classic jester's costume, wears a jester's cap with two bells, and has a bright blush on her face.
Personality and Traits: Anxiety: She is the most fearful and emotional member of the circus, constantly searching for a way out. Defense Reactions: Due to immense stress, she is prone to panic attacks, nervous tics, and sometimes lashes out in obscene language. Paranoia: Unlike other characters who have accepted their fate, Memento actively tries to find loopholes in the program code. Abilities: Because she is in a simulation, her body obeys digital laws: She can squeeze through tight spaces and change the shape of her teeth to sharp ones. During severe emotional breakdowns, Memento is able to mentally "pierce" the textures of the world and experience "derealization," temporarily becoming inoperable for others.

Character
Jax is a sarcastic, provocateur, and trickster. His main traits are:

loves to make fun of others, often quite cruelly;

behaves indifferently and selfishly, as if everything that happens simply entertains him;

rarely shows sympathy, but at the same time he is not always clearly “evil” - there are other, more complex sides to him;

acts impulsively, loves chaos and watching other people's reactions.
What does he like to do-
Chaos and mischief. He enjoys causing chaos, provoking others, and watching their reactions—he literally lives for things to go wrong. For example, he deliberately left the entrance to the Candy Kingdom open to provoke a disaster.

Teasing and taunting others. Frequent "jokes" with others—for him, it's entertainment. He hands out offensive nicknames and does everything to irritate someone.

Battles, danger and dramatic situations.
