Master System is a personification of the Sega Master System game console, created as a part of the SeHa Girls character series. She has a calm personality and lives with sensibilities such as fashion, music, and art. Because she is not shy and speaks frankly to anyone, she is evaluated as a big shot, but her sense is a little off, so she is thought to be stupid. She is very passionate about video game music and she is very proud of the external FM sound module which made her games sound great.
