Tsubomi is 14 years old and in the second year of the private Myōdō Academy’s Junior High School branch. She loves flowers. She has just moved to Kibōgahana [the town’s name, meaning “Flower of Hope”], where her grandmother lives. She loves every plant and would like to join the gardener’s club, but then she is taken into the Fashion Club by Erika. Her house is the “Hanasaki Flower Shop”. She is an upright person, but also shy and withdrawn, which is almost a complex of hers. She sees her change of schools as a chance to change herself. Indeed, after she meets Erika, she will slowly start to change. In the first fight when Erika was controlled as desertrian, she wants to save Erika and is half-forced by fairies to become a Pretty Cure. As Cure Blossom, her theme color is pink and her flower symbol is the Cherry blossom. Her powers are related to flowers and she can use auxiliary attacks such as Blossom Flower Storm and Blossom Double Impact in addition to her finishing attack. Her catchphrase is “I can’t put up with this anymore!” (私、堪忍袋の緒が切れました！, Watashi, kan-nin-bukuro no o ga kiremashita!).
She introduces herself as “The flower spreading through the land, Cure Blossom!” (大地に咲く一輪の花、キュアブロッサム！, Daichi ni saku ichirin no hana, Kyua Burosamu!)
- Blossom Oshiri Punch (ブロッサムおしりパンチ, Burosamu Oshiri Panchi): Cure Blossom kicks herself into the air backwards to hit the enemy with her buttock. She can only use this when influenced with the red Heart Seed to speed her up. However, she seems to be capable of using it without the red heart seed.
Blossom Shower (ブロッサムシャワー, Burosamu Shawā): Cure Blossom draws a circle of pink flowers before her before shooting them at the enemy.
Blossom Flower Storm (ブロッサムフラワーストーム, Burosamu Furawā Sutōmu): Cure Blossom circles around herself, summoning numerous of pink flower petals around her to create a tornado of it.
Blossom Impact (ブロッサムインパクト, Burosamu Inpakuto): Cure Blossom concentrates all her powers into her palm and strikes at the enemy; pink light will then shine, and the enemy is knocked away.
Blossom Double Impact (ブロッサムダブルインパクト, Burosamu Daburu Inpakuto): An upgraded version of Blossom Impact. Cure Blossom consentrates all her powers into her palms and strikes at the enemy; pink light will then shine from both hands, and the enemy is knocked away.
Blossom Screw Punch (ブロッサムスクリューパンチ, Burosamu Sukuryū Panchi): Cure Blossom collects energy into her fist and shoots it out as a concentrated beam.
Pink Forte Wave (ピンク・フォルテウェイブ, Pinku Forute Ueibu): The finishing attack that Cure Blossom uses, used to purify a Desertrian. Cure Blossom summons her Blossom Tact and spins the center of the tact, and rainbow lights go into the gemstone tip of the tact. The tips surge with purity energy, and Cure Blossom spins before declaring the attack name. She then shoots out an energy flower at the Desertrian. An implosion occurs, and the target is suspended in the air, a cherry blossom having overlapped behind it. Cure Blossom claps the center of the Blossom Tact to keep the center spinning, and in a flash of light, the enemy is purified. The move can only be used by Cure Blossom only. Cure Blossom says these lines after she summoning her Flower Tact: Gather, Power of Flowers! Blossom Tact! Sparkle, Flowers! Precure Pink Forte Wave! (集まれ、花のパワー！ ブロッサムタクト！花よ輝け！プリキュア・ピンク・フォルテ・ウェーブ！, Atsumare, Hana no Pawā! Burosamu Takuto! Hana yo, Kagayake! Purikyua Pinku Forute Uebu!)
