kaminomi (The World God Only Knows) [TV]

Keima Katsuragi, a second-year high school student, is an avid bish?jo game player. He is known on the Internet as “The God of Conquests” (??

After winning the hearts of several girls (and capturing the spirits residing in them), Keima and Elsie are given an even greater mission: to awaken the six goddesses who are daughters of the god Jupiter, the “Jupiter Sisters”. Each sister is dormant in the heart of a girl a
