Happy World!

Japanese Title: ハッピーワールド

Plot
Takeshi Ōmura is an average middle schooler cursed with the bad fortune, as his every day life is a misery; He has this case of bad luck ever since he was little. His house burns down, he sets his hand in dung, he gets chased by a wild dog and all sorts of activities that ruin his life. One day, while on his normal runs with bad luck, he is visited by an angel with the name of Elle, and he finds out that his father wished the curse of bad luck upon him. She claims that she came down from the heavens to aid Takeshi in his misfortune. To get rid of his bad luck, he places his bad luck in a small ball with the help of Elle and throws it out of sight. As Elle leaves and Takeshi continues his daily life, he finds the ball again and decides to wait for a person to pick it up. Unfortunately, a young girl sees the ball and moves into a path of a moving truck. Takeshi, realizing that he wouldn't be happy if he didn't save the girl, touches the ball and shouts that he would be the successor of the bad luck if saved by Elle. The angel transports them to a backyard of a house and becomes a human (experiencing gravity and a tangible body). From then on, Elle becomes human and lives at the Ōmura household (and adopting the name to her own), to protect him from the curse and attends Takeshi's school, which is something Takeshi isn't particularly happy with.
