The genius mechanical inventor of Nod-Krai. She lives in the Clink-Clank Krumkake Craftshop, surrounded by her mechanical family and the fragrance of the workshop's namesake — scrumptious krumkakes. In spite of her young age, Aino is an extremely talented mechanic, claiming that she had both dismantled and reassembled just about any machine in Nod-Krai. Despite the use of scrap metal from every nation and purposely using only secondhand scavenged parts, Aino's creations are considerably powerful, being on par with more modern equivalents, such as Knuckle Duckle, said to be on par with the Fatui's modern machinery, the Boom and Blast Kuuvahki Cannon, which protects the people of Nasha Town from The Wild Hunt if they become too dangerous, and Ineffa, her personal robot maid. Aino still shows several childish behaviors, such as an obsession with sweets (like krumkakes and chocolate), going on tantrums and a desire for companionship, which she fulfills with the creation of numerous robots, viewing them as both her creations and family. This was shown after she let Ineffa leave for Natlan to find the Traveler, as Demyan explains that Varka discovered that Aino went "wild" on snacks without Ineffa to monitor her diet, causing the concerned knight to step in and help make some arrangements for at least one balanced meal for her per day until Ineffa returned. Likewise, when Krum-Clank 70% Sweet was abducted, Aino became enraged and sought to seek the party that stole it, with Ineffa claiming that she would have caused a huge crisis if it were not for her and the Traveler's intervention.
