|(花月月子, Kagetsu Tsukiko)|
|Anime||Naruto Episode #186|
|Appears in||Anime only|
At the beginning she was very greedy and only returned to her clan when she thought she could get a portion of her father's money because of his fake death. At the end of the episode when Tōbei revealed that he faked his death so that his kids could find humour in life, she understood and found her humorous side.
Tsukiko has oddly shaped black hair and bluish-coloured eyes along with red lip stick.
She had left the Kagetsu Family five years before and returned when her father Tōbei Kagetsu supposedly died. His will specified she could inherit a portion of his fortune if her older brother Fūta Kagetsu was to laugh during there father's funeral. She and her fellow clan members did their best to make him laugh. She was shocked when Tōbei revealed he was alive and faked the whole thing. When he stated he wanted them to not focus on money and enjoy life again, she once again could find some humour in life.
- The 'tsuki' in Tsukiko's name means 'month 'and the 'ko' means 'child'. So her name means 'month child'.
