Nami Tachiba
Nami is a classmate of Ichitaka, Iori, Teratani, and others, and is generally the mood-maker of the group whenever they are all together on a trip, school project, etc. She is very energetic and cheerful and loves to express herself, though her tomboyish and carefree attitude can make others feel awkward at times. She comes from a very rich family, as it is evident halfway through the manga when the group comes over to her house to organize a group project. Some interpret her as a female pervert, since she has tried to get people to sleep together and has shown off her body numerous times.
