Omishi Mahou Gekijou: Risky★Safety

An apprentice shinigami (Japanese Death God), Risky, is determined to take Moes life. However, Risky is magically joined with an apprentice angel, Safety, so Risky turns into Safety whenever someone says something nice. As an apprentice shinigami can only take someones life when that person is really depressed, Risky has quite a problem taking Moes soul, while dealing with Safety, who often cheers Moe up.
