Memine

Memine is a cat who lives on Viginti together with Ginti, and helps him with his duties as an arbiter. Despite clearly being an animal, she seems adept in the tasks she has been given. Memine means 'remember' in Latin, and this may refer to the fact that she seems to remember people, like Mayu, which may elude to where Memime currently is.

Appearance
Memine is a black cat with green eyes. She has a stump of a tail and a bandage wrapping around her right foreleg.

Personality
Memine seems like an obedient, smart, playful friendly kitty. She was close to Ginti and acted as his assistant, being adept and understanding her duties as she helped him in executing his games. She was still playful like a normal cat as she played with one of Mayu's fake eyelashes. She was also friendly towards Mayu, much to Ginti's jealousy. However, either out of closeness to Mayu or out of dislike for Ginti's actions, Memine left after Ginti sent Mayu to the void, as Ginti states she hasn't come back since.

Plot
She acted as Ginti's assistant. In episode 6, the game selected for Mayu and Harada to play was Twister and she would push the button that would tell the player what part of their body to move and on what color. She was seen in the post credits scene playing with Mayu's fake eyelashes as Harada performed an inpromptu concert. In episode 7, she was shown being friendly with Mayu. In episode 11, she was shown watching over Ginti and Mayu's discussion over whether Mayu would be willing to send a soul to the void in place of Harada's and left Ginti after he sent her and Harada to the void.

Ginti
She has a strong bond with Ginti as he was shown holding and petting her frequently. When Mayu noticed a cat, Ginti demanded for her to call the cat by her name Memine, showing he was protective of her. She was also competent in her abilities as Ginti's assistant, which showed he trusted her. He was jealous when Memine warmed up to Mayu, calling her a traitor. She left him after he sent Mayu to the void, and Ginti seems upset by this.

Mayu Arita
She seems to have liked Mayu as she was fine with Mayu picking her up and even cuddled towards her, nudging her head affectionately towards her. When Mayu was judged to go to the void, Memine jumped out of Ginti's arms and left.

Trivia

 * She seems smarter than an average cat as she knows her duties as an assistant arbiter.
 * Her fate remains unknown as she had left Ginti in episode 11.
