Ryu Yamada is a second year student at Suzaku High. He is always late for school, naps in class, and gets abysmal grades. His life is a dead bore.
According to Urara Shiraishi, Yamada has the ability called "Duplication". When Yamada kisses one of the witches with special powers he replicates their power and uses it when he kissed a normal person. If Yamada kisses another witch then the abilities he had won't affect the said witch. This can be seen when he kissed Nene Odagiri he didn't swap bodies with her or when he kissed Urara after he replicated Nene's powers she didn't fall in love with him.
