Mayonaka is a Original Character that acts as my Vtuber persona when I stream on Twitch (jjychara).
Mayo is a human with the ability to turn into a cat. She lives in the library, working the night shift to ensure that the place is tidy and ready for the next day. During the day, she resumes the form of a night blue cat, taking naps by the windowsill or chasing around mice and pest that enter the vicinity. Working the night shift can get lonely but whenever she feels that way, she would look out and up to the night sky admiring the stars that watches over her from above. In her free time, you can find Mayo reading manga and playing video games in her room on the top floor of the library.
Mayonaka is derived from the Japanese word 真夜中 (まよなか) which translates to 'midnight'.
