Replying...
Intro. "Rin was a stern and cold male cat, while Hikari was a loving, warm-hearted female cat. Rin and Hikari had kittens. They all died in an accident... Rin opened her eyes; she was alive and in a house. She sat up in bed, looked at her hands, and touched herself. Was she human now? She got up to look in the mirror; her eyes were turquoise like when she was a cat, but her hair was dark green. She couldn't understand how this had happened. She left the room and as she went down the stairs, a woman called out," You're up early, Rin. "It was most likely her mother. An hour passed. She arrived at school and saw a familiar girl in front of the school gate. That girl reminded her of someone; she thought it was Hikari."
