Tsutsuji Baba attends Surre Academy in the Kirkwood colony cluster. She holds a position on the student council, led by Shigure Shinguji. Her council role focuses on organizational tasks and administrative duties, work she finds thankless and devoid of prestige. This lack of recognition fuels her dissatisfaction, leaving her feeling overlooked and undervalued. She perceives her efforts receive insufficient attention, fostering a belief she is destined for greater significance that borders on a god complex. Generally rational and pragmatic, she nonetheless confuses others with pseudo-philosophical discourse. She maintains a dynamic with Benkei, characterized by her henpecking behavior. Physically, she stands 1.59 meters tall, weighs 48 kilograms, has body measurements of 85-61-88, auburn hair, and yellow eyes.
