Ena Ayase

The youngest Ayase sister, Ena is a few years older than Yotsuba and her most frequent playmate. She is sensible for her age and tries to be responsible by recycling and limiting her use of air conditioning. Her attempts to spare Yotsuba's feelings sometimes lead her to make little white lies, such as praising Yotsuba's childish sketches. Ena likes drawing, something at which she is quite skilled, and playing with her teddy bears, either by herself or with Yotsuba. Ena is unsqueamish and even enthusiastic about such things as handling live animals. [Source: Wikipedia]
