谷田部 乃愛

Yatabe Noa is the elder sister of the Yatabe sisters, and as the granddaughter of one of the most powerful corporations of the world she’s grown up to be pretty sheltered. Generally speaking, she’s a nice person who’s aware of her naivete (but not her complete inability to cook), and while she’s not the most social person in the world, she is popular enough to be the school idol. Unfortunately for Kojirou, Noa is also extremely protective of her younger sister.[From Choux's review.]
