Tenshin Ranman: Happy Go Lucky!!

Haruki Chitose is the unluckiest person alive, and has fully accepted it: losing his wallet repeatedly, drowning his phone, getting hit by things, stumbling into trouble while simply walking down the street — this is just Tuesday. Then a package arrives with no sender, addressed to nobody, labeled "living being." Inside is a girl who claims to be a goddess sent specifically to end his bad luck. She moves in. The bad luck does not improve. The chaos increases considerably.
