Ena is older than Akito by one year, but Akito is the tallest one of the two. They bicker over the smallest things often. Ena would sometimes invite Akito to come try his favorite food, cheesecake with her from different shops. She would also drag him around to carry her shopping bags or take pictures. But deep down, they both care for each other but rarely show it. Ena is sweet and likes to draw and post selfies online. Akito acts polite and kind to strangers but drops the act around familiars.
