Nanaho is one of the two vice presidents of the Gokujou Seitokai and also the leader of the Assault Squad, using a yo-yo as her weapon. She is very afraid of lighting as she flinches horribly when it strikes and cries out causing people to look at her strangely and she quickly and angrily yells "What?!". She secretly has a great love for "girly" things, which can be seen from the decor of her room. This provides a stark contrast to her tomboyish outer appearance and behavior. She was first skeptical by the idea that Pucchan was magical, but later learns that he can talk on his own hand. Nanaho is also an old friend of Kanade and protects and advises Kanade in various matters by her own free will, and not because of the obligations that have been bestowed to the Kinjo family to protect Jinguuji family from generations ago. She has 6 brothers and she is the youngest child of her family. Since childhood she was trained to protect Kanade, which caused her to bear a grudge towards the other girl until Kanade told her that she was free to do as she wanted.
