Despite these hardships, Nana "polishes the shards of her dreams" and is determined to be successful as the lead vocalist of Blast. She is now engaged to her first love, Ren Honjo, although she also has lingering, ambiguous feelings for Yasu. Nana's favourite things never change. Her favorite designer is Vivienne Westwood, and her favorite band is the Sex Pistols. She smokes Seven Stars and likes coffee with milk and strawberry cake.
