Watanuki Nezuki

Zakuro's older brother.

His real name is Nezuki, but he prefers to be called by his nickname Akoya, which was given to him by his schoolmates.

He's enjoyed painting since he was a child, but he always felt somewhat unsatisfied with his work.

One day, he is reunited with Zakuro, whom he had lived apart from, and becomes convinced that she is a goddess whom he should devote his life to painting.
