Tsukino with her grandfather.
Tsukino Azusagawa is the granddaughter of the owner of the Pantasia chain, and understudy to Ken Matsushiro, who has difficulty getting along with the rest of the Pantasia-involved Azusagawa family because she is an illegitimate child. She is still very dedicated to the Pantasia chain, seeking out talented new bakers (like Azuma and Kawachi) and has garnered the support of many other characters. While she stays behind the scene most of the time, she is implied to be talented, as she managed to make it to the third place of a past newcomer's battle at a very young age.
Appearance
She appears to be the prettiest of the Azusagawa sisters and many men find her attractive, proven as she was able to charm them out into trying Kazuma's Kabukiage bread in their store. She has long flowing light brown hair and green eyes. One of her distinctive style is that she always wears ribbons.
Personality
Contrast to her sisters (of which hate her due to her 'thieving-cat' mother), Tsukino is good hearted and forgiving. She is also implied to be a good baker, a good example is before the newcomer's competition in which she was said to have come 3rd place a few years ago.
She seems to have romantic feelings for Azuma, though it is never explicitly stated.
History
Her mother died 4 years before the current time in the series.
Although her grandfather loves her the most (as he loves all three of his grand-daughters), it seems that her own father takes little notice of her, favouring her younger sister much more. She therefore has no family, although Ken Matsushiro (the manager of her branch) purposely decided to work there to act as somewhat of a family-replacement figure.
