Matsuri is the youngest and only female of the Tatsumi siblings. She belongs to the National Seaside Hospital. She was born on December 21, 1979. She acts as an ambulance driver and a nurse. A kind hearted girl, she is a strong fighter who is very agile and quick. She does not take it kindly when others weaker than her are in trouble and her temper can be pretty deadly when the Saima Clan attack innocent people. Even though Matsuri is the youngest, she is the one that brings order in the household when the males of the family get out of line. She had a best friend and they were very close. They both fell in love with the same doctor. Matsuri did the only thing she could think of as right. She stepped aside and left the field for her friend, though it nearly broke her heart. She made certain neither of them had a clue as to the depth of her feelings for him. Until her brothers unwittingly exposed the fact to the doctor in question. But things were settled, and they attended the wedding and wished the couple well. When it came to their mother, Matsuri was the most determined not to forget their mother, the hardest to accept that she was dead. And ultimately, it turned out that she was right. When Pierre returned and began terrorizing the city, Matsuri and his family came out of retirement and helped the Timerangers defeat the Saima demon.
