Description
Hariham Harry is a hamster-like fairy from the Harihari Clan in Harihari Township's future timeline. Alongside childhood friends Listol and Bicine, Harry confronted a deadly outbreak that infected Bicine and others. Desperate for a cure, Harry and Listol joined Criasu Corporation. Criasu granted them human forms but deceived them, leading to their hometown's destruction. During this time, Harry crossed paths with Cure Tomorrow (the future Hugtan). Her kindness motivated him to defect from Criasu. He freed her from captivity, though both were cornered by Bicine until the White Mirai Crystal transported them to the present day.

Harry first appears falling from the sky with the infant Hugtan while fleeing Criasu. They land near Hana Nono, whom Harry initially distrusts as a protector. After Hana transforms into Cure Yell to defend them, Harry establishes "Beauty Harry," a fashion shop serving as their base. As Hugtan's caretaker, Harry prioritizes her safety and nutrition, often using the Mirai Pad to find resources. His gold chain necklace, later revealed to suppress a monstrous form, is central to his character. When Bicine breaks it in a confrontation, Harry transforms into a large, gray-furred creature with crimson hair, red eyes, sharp claws, and fangs. In this state, he acts destructively until calmed by Cure Tomorrow or Cure Étoile. Over time, Harry learns to accept this aspect, eventually gaining control over the transformation.

Harry exhibits high confidence but reacts with hypersensitivity to being misidentified as a mouse, frequently correcting others by declaring himself a "harriham." He boasts about his handsome human form—a cool young man with red hair, blue eyes, a leather jacket, and retained gold accessories—yet remains caring and loyal, especially toward Hugtan. His relationships are complex: he views Cure Tomorrow as his true love and cannot reciprocate Homare Kagayaki's romantic feelings, though he supports her as a friend. His bond with Bicine is strained by Bicine's pathological obsession, while his friendship with Listol fractures due to Listol's pessimism and allegiance to Criasu. These conflicts culminate in physical fights, but after both are purified, Harry reconciles with them.

In the finale, Harry voluntarily removes his chain to embrace Listol, catalyzing Listol's defection from Criasu. He returns to the future with Hugtan and other redeemed Criasu members. Twelve years later, he is seen peacefully coexisting with Listol, a rejuvenated Bicine, and companions. A human-form Harry also appears alongside Cure Tomorrow, sensing the birth of Hana's daughter.

Harry's abilities include assuming human and combat-ready forms. He demonstrates proficiency in physical fights against Listol and harnesses "Tomorrow Power" to create protective barriers or regenerate his chain. Biologically, harrihams are classified as mysterious rodent-like creatures unexplained by evolution. A recurring gag involves characters mistaking him for a mouse, highlighting his species pride. Harry speaks in a Kansai dialect and is the franchise's first male mascot with independent combat prowess and the first to transform into a monster.

His name is etymological: "Hari" means "needle" (referencing hedgehogs or his spiky hair), while "Hamu" abbreviates "hamster." The full name "Hariham Harry" forms a pun.
