Overview
Aino is a four-star Hydro Claymore character in Genshin Impact from the Nod-Krai region. She is a child prodigy and mechanical engineer who operates the Clink-Clank Krumkake Craftshop outside Nasha Town. After arriving in the area as an orphan, her extraordinary aptitude for mechanics led her to found her own workshop. Living alongside her versatile household robot creation, Ineffa, she develops and maintains numerous technological inventions and infrastructural devices throughout Nod-Krai.
Appearance
Aino is depicted as a young girl with bright blue eyes and extremely long pink hair featuring a prominent ahoge, pinned-back hair, and distinctive hair clips. She wears a sleeveless layered black-and-green dress with bloomers underneath a white lab coat with sleeves extending past her fingers. Her lower body features a band-aid on her left thigh and mismatched socks paired with green footwear. A mechanical tail made of pink tin cans extends from her backpack, which also displays her Hydro Vision.
Personality
Despite her engineering brilliance, Aino possesses the demeanor of an ordinary, whimsical child. She holds deep affection for her mechanical creations, treating them as cherished family members. She is obsessed with sweet desserts—especially whiteberry krumkakes made by Ineffa—while despising salty baked goods or hard crispbread. Completely incapable of doing household chores, she frequently gets scolded like a child by Ineffa whenever she eats too many sweets or throws a tantrum over missing machinery.
Abilities
In combat, Aino wields a claymore and specializes in Hydro application and Elemental Mastery buffing to support reaction-based teams. Her Elemental Skill launches a mechanical arm from her back to deal Hydro damage while pulling her toward the target. Her Elemental Burst deploys a bird-shaped water-sprinkling machine that periodically deals Hydro Area of Effect damage over a wide field, amplifying damage for Bloom, Electro-Charged, and Lunar-type elemental reactions.
Background
As a wounded orphan, Aino originally washed up at the Speranza restaurant in Nasha Town. Her innate knack for machinery was discovered when she easily solved an engineering problem for a local artisan, after which she trained under a wandering technician known as 'Wrench Pops.' She eventually built her own workshop and invented major regional infrastructure, including the Krumkake Laser Cannon and widespread imaging devices, establishing her life alongside Ineffa and her machine companions.
Relationships
Ineffa, a versatile household robot she built, acts as both family and a maternal guardian who manages Aino's daily life. She learned her craft under her master, 'Wrench Pops' Chesternin, and later took on Xincha as her student. Through various incidents involving missing workshop tools and machinery repairs, she forms close friendly ties with the Traveler, Paimon, Yaqoda, and Phrenes.
Trivia
Aino is notable as the very first Hydro Claymore user in Genshin Impact, completing all 35 possible element-weapon combinations in the game. Fans frequently draw parallels between her character dynamic with her robot creation Ineffa and the relationship between Hakase and Nano from the anime and manga series Nichijou.
