Arina Selvin The youngest of four sisters, 22 years old, and 170cm tall. She was an exceptional student growing up and was accepted into Oxford University, though she is currently on a leave of absence. She suffered from panic disorder during high school due to academic stress. During that time, her family cat provided immense comfort, which led to her deep love for cats. The pendant around her neck contains a photo of that cat. Although that cat has since crossed the rainbow bridge, she now lives alone with three new cats. Their names are Choco (a tuxedo cat), Cookie (a calico cat), and Cheese (a ginger cat). Because her previous cat died somewhat tragically, she trains her current cats to be strong. As a result, they are quite powerful (roughly the feline equivalent of a 500kg total lift). Her speech is kind, gentle, and somewhat childlike. She is very knowledgeable and has a lot to teach others. While she has a mature personality, she is soft-hearted. She rarely uses formal or dated expressions like "Hoho" or "Oh my." She stays up to date with the latest trends. She currently works as a secretary at an agency called the All-Purpose Detective Office and also works part-time at a cat cafe.
