Birthday: July 2
Sign: Cancer
Height: 157cm
Weigh: 53kg
Blood type: O
Favorite Music: Classical music.
Experience with playing musical instruments: Started playing piano at
age four. Picked up keyboard upon joining the Light Music Club.
Family structure: Family of three, both parents. Father is a president
of a company. There is a butler at the house. She is being treasured as
the only daughter.
Dwelling: Single-family home, a rather stately mansion.
Commute to school: By train (she lives two train stops away from the
school). Because being driven to and from school by car is embarrassing
for her, she avoids it.
Preferences in clothing: Skirts over pants. High society lady styles, such as elegant one piece dresses.
Her room: Canopy bed, antique furniture and such, as expected of a rich
girl's room. The room is decorated mostly according to her parents'
tastes.
Favorite food: She prefers traditional sweets such as daifuku (rice
cakes with red bean jam filling) because she worries about calories and
because western sweets are brought to her house all the time and she is
tired of them.
Subjects she is good at: If anything, humanities, though she is also
above average at science and math. While she is a little weaker than Mio
when it comes to math, her math skills are certainly above her grade
level.
Subjects she is bad at: No subject is particular.
Physical activity: Tsumugi is gentle and quiet and as result she is not
good at ball games and track-and-field athletics. However, she has a lot
of arm strength and amazing hand grip. She is a very strong girl.
Way to pass the time when alone: Elegant teatime
Weaknesses and dislikes: She is a little worried about her predisposition to gain weight easily.
Tsumugi, often referred to as 'Mugi' by her friends, is a wealthy
girl with a gentle and sweet personality who plays a Korg Triton Extreme
76-key keyboard, though she is also seen playing a Korg RK-100 keytar
in the closing credits of the first season. She originally intended to
join the choir club, but joins the light music club instead after
receiving an invitation and encouragement from both Mio and
Ritsu.Tsumugi is considered a piano prodigy since she has been playing
the piano since she was four and has experience in winning various piano
contests. Mugi has long, pale blonde hair, blue eyes, unusually large
eyebrows, which apparently run in her family and a fair complexion that
the other characters do not have, but she does not get sunburned. She is
the daughter of a company president, and her family has several villas
in various places around Japan (and even one in Finland).Since her
father also owns a maid café, she often brings confectionery and an
assortment of sweets and pastries to the club room, and she diligently
makes tea with a tea set which is kept in their club room. Despite her
wealth, she is fascinated by and finds joy in "normal" activities, such
as ordering fast food, sharing french fries with her club mates,holding
down part-time jobs and haggling over prices.Tsumugi displays a
rebellious streak occasionally, diverting from her normally well-behaved
and mature demeanor to the surprise of the others. She also displays a
childlike eagerness from time to time, and possesses unusually high
strength, being able to effortlessly carry around her own keyboard,
Ritsu's drums, amplifiers, and at one point beating an arm-wrestling
game in an arcade.
Tsumugi is often entranced by the sight of two girls interacting
closely together, sometimes imagining something more risqué in her head.
The series sometimes indicates that Mugi has a crush on their teacher,
Sawako Yamanaka. While a lot of things do not bother her, she is fairly
conscious about her weight (just like Mio), and she gets a bit anxious
when her family's staff start spoiling her friends during villa visits.
She later begins learning how to play the guitar from Azusa. Tsumugi has
a childhood friend several years younger than her named Sumire Saitō
who is a daughter of the family that serves the Kotobuki household.
Tsumugi grew up home schooled, and therefore spent very little time in
the outside world. Because of their close friendship Sumire would
purchase everyday items like manga for Tsumugi that she was not normally
allowed to see. Tsumugi was rather taken by some of the yuri manga she
received which may have influenced her later perceptions about
relationships. When Sumire started high school, Tsumugi wanted her to
experience the light music club on her own, but due to Sumire's shyness
Tsumugi came up with the excuse to send her to the club room to pick up
the tea sets that had been left there and told Sawako when Sumire did
join that it was okay to leave the tea sets there.
