Yachiyo

As part of her programming, Yachiyo follows through her job as hotelier seriously while interacting with the other robotic staff to follow routine and accomodating guests. Even when the guests are of extraterrestrial origin, she treats them with sincerity irregardless of alien language until she eventually updates her bilingual skills thanks to Ponko after her family arrived to Earth. Presumable overtime, Yachiyo's program has reached the point of singularity where she develops an emotional sidem like when she gets upset over the hotel's business just because there is no shampoo hat.
