Moetan's heroine. She lives next door to Nao and is infatuated with him. Even though she is 17 she is often mistaken as a grade-schooler, however she makes up for it with her high grades, especially in English. She meets Ah-kun who gives her the power to transform into the magical hero Pastel Ink; using a pink flip phone, changing through that of into a duck-like outfit with blue hair. Using this new power she helps the people of her city while also using it to tutor Nao in English. In episode 12 she has lost her magical abilities but still continues to tutor Nao under her own design of Pastel Ink and gets into the same college as he; she has not yet revealed to him that she is Pastel Ink. Ink's quirks are that she is very clumsy, often tripping over nothing, a trait she seems to have gotten from her mother; and becoming entranced to the point of drooling at the thought of being alone with Nao-kun.
