The World God Only Knows, Volume 10 (The World God Only Knows #87-96)

Keima faces the predicament of being a girl, while his current capture target, Yui Goidō, is inside his body. Seeing that it will be hard to capture by being a girl, with the help of otome games, Keima is able to make Yui 'capture' him. But within Yui was a level 4 spirit, a spirit that is independent enough to be able to talk and think individually. In the end though that spirit is captured by an unknown someone. Keima's next capture is Kusunoki's older sister, Hinoki Kasuga. He watches Hinoki, seeing her grow large because of the spirits powers. For now, he's the only one who can see her in such a state. But what is causing the gap in her heart...?
