Though a kind child, and highly protective of his sister, Sayoko, Mamoru begins to change after his father fails to fulfill a promise with him. As his father's business goes bankrupt, he begins to obsess about "useless things". After a pillar of light pierces the sky, Mamoru believes he has gained the ability to destroy these useless things, but the truth is that he can only chose what is to be destroyed.
