A young woman quietly falls to the earth, escorted by a solitary crow. This sort of dream, as many other before have dreamed, comes just before being reborn as a Haibane, a charcoal-winged angel.

Rakka is the newest inhabitant of Old Home who wants nothing more than to remember her past and discover the secrets of her kind. Together with Reki, Kuu and plenty of other new friends, Rakka will laugh, explore, and search for the meaning of their existence in the process.

Between being molested, propositioned, having his face shoved between mammoth breasts or witnessing endless panty shots, Kouta must also attempt to maintain his studies – even though all Chizuru and Nozomu want is to be the one to deflower him first!
Both these titles are wrapped up in Ecchi and humour. Although Kanokon is more 'tame' than Sora no Otoshimono both are somewhat of a fantasy/sci-fi type romances. They both show different sides of their story, with Sora no Otoshimono having an aggressive (trying to get girls) protagonist and Kanokon having the passive (trying to be won over) protagonist.
