Nami Tachiba

Nami is a classmate of Ichitaka Iori Teratani and others and is generally the moodmaker 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.
