Etsu Kusuda

He is a pervy friend of Mamoru's. His talent is putting girls to sleep with stupid puns. He doesn't see much in Ayumi, but he is very interested in Misaki; he is nearly obsessed with her. He seems undaunted by Kei's good looks, and with his "Kappa" face, they tend to bicker a lot. Also he is left-handed. (Source: Wikipedia)
