Ai Yuu is everyone's older sister. Although she is hardworking, she can be lazy at times and try to escape to a different world. Sometimes she's a bit timid, innocent, and clueless about online trends, memes, and even VTuber stuff.
She strives to be a nice older sister to everyone and create a good impact on other people's lives.
Ai Yuu is a behaved ojousama in the family, currently trapped in their house to serve the family. But deep inside, she longs for freedom, happiness, and her purpose in life.
