Jiyu is a new 8th grader in
class 2B at Hontsuru Jr. High
School and is the daughter of
Sai and Makoto (deceased). Since
she and her dad live alone she
has many responsibilities in the
house, including cooking, which
she enjoys. While she seems to
be a normal 15 year-old, she is
far from typical. When she puts
on the heart-shaped eyepatch,
she becomes the successor of
Yagyu Jubei. Jiyu doesn't like
this at first because she just
wants to be herself. However, as
time goes by, she realizes that
she has to fulfill her role.
 
Secondly, she is a bit
precocious, in the physical
sense. This is what the guys in
the story first see, many of who
fall in love immediately because
of her looks. However, Jiyu is
extremely naive to this fact. In
addition to being forgetful, she
never fully realizes why so many
people are interested in her.
However, she has a good heart
and treats everyone who likes
her very well.
