Tsukiko Kagetsu

is a member of the Kagetsu clan and the daughter of Tōbi Kagetsu.

Personality
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 Tōbi revealed that he faked his death so that his kids could find humour in life, she understood and found her humorous side.

Appearance
Tsukiko has oddly shaped black hair and bluish-coloured eyes along with red lip stick.

Part I
She had left the Kagetsu clan five years before and returned when her father Tobi 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 Tōbi 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 humor in life.

Trivia

 * Tsukiko had married but it is unknown if she changed her surname from Kagetsu to the new one.
 * The 'tsuki' in Tsukiko's name means 'month 'and the 'ko' means 'child'. So her name means 'month child'.
