Latte, the puppy-like fairy and Princess of the Healing Garden, boasts light beige fur, wide purple eyes framed by rosy cheeks, and pastel purple bows adorning her ears. A golden heart ornament rests on her forehead, shifting to yellow when her health falters, while a fuchsia bow with a delicate pink flower accents her neck. To communicate, she uses a stethoscope that channels her inner voice, often punctuating sentences with “~latte,” though she gradually learns to speak unaided as her powers mature.

Sent to Earth with three Healing Animals to recruit allies against the Byogens, Latte collapses upon sensing a Megabyogen’s approach, only recovering after forming a bond with Hanadera Nodoka. Her curious nature leads to frequent wanderings, yet her loyalty to companions remains unwavering. After Fuurin Asumi—a spirit born of Earth’s energy—saves her from captivity, their bond deepens. Together, they navigate Asumi’s overprotectiveness, forging a partnership rooted in mutual trust and a commitment to heal their world.

Latte’s powers let her detect Byogen infections at the cost of her vitality, while Element Bottles on her collar purify infestations but not mundane illnesses. As she grows, she masters healing others, even revitalizing the Cures post-battle, and hones skills like flight and clearer speech—though she still sometimes fumbles names.

Her trials include enduring separation anxiety, captivity by foes, and life-threatening sickness triggered by Byogens. In a defining act of defiance, she rejects returning to the Healing Garden, choosing Earth as her battleground beside Asumi. Post-victory, she resumes her royal duties but reappears to aid the Cures in later crises, showcasing refined abilities and newfound independence.
