Natsu is an expert
volleyball player for Gorin High school. She is competitive, smart and
determined to protect her teammates. Many of her schoolmates look to her as a
sister figure. She dislikes liars and people who bully the weak. She tends to
act more like a man than a girl, and many guys in her school are actually
afraid of her. On the flipside, her female schoolmates love her. Although many
see her as boyish, Natsu is an excellent cook, and has the heart of a girl who
longs for true love...
In the first Rival Schools, her motivation is to find the people
responsible for attacking Gorin High, which included the highest-ranked member
of the school volleyball club. She joins Shoma
and Roberto to investigate, and
through it all, she argues with Shoma over how to go about it.
In Project Justice, Natsu is suspicious of a new student named Momo.
Shoma believed that they should help Momo, but Natsu disagreed. After Shoma
leaves to investigate on his own with Momo, Natsu joins Roberto and Nagare
to find culprits of the new school disturbance. Later, she is the first to
welcome Shoma back after Momo betrayed him. Natsu
also wanted Momo to be expelled from Gorin High after the incident that nearly
destroyed their friendship with their own schoolmates, and those from other
schools as well.
