Sora no Otoshimono: Forte EP2 - Bombshell! The Angel is a Big Boob

Tomoki, much to his irritation and confusion, finds himself aroused by the antics of Ikaros and Nymph. This disturbs him greatly so he leaves for the mountains to train in the Zen monastery. At the same time, Astraea, the new angeloid lands at the monastery to dispatch Tomoki while Sugata informs the rest about her. Nymph and Ikaros ignore the threat calling Astaea an 'idiot' and leave Tomoki alone who himself is finding trouble ridding himself of his 'earthly desires'. Later, Sugata discovers Astraea and learns of the threat to Tomoki's life and more information on Synapse, the world where Angeloids come from.
