Tenchi Muyou! GXP

Seina Yamada has lived with such catastrophically bad luck that accidents seem to follow him everywhere. A chance encounter with Galaxy Police officer Amane Kaunaq changes his life when an application meant for Tenchi Masaki ends up drawing Seina into the interstellar law-enforcement organization instead.

His misfortune does not disappear in space. In fact, it becomes strangely useful because pirate fleets are repeatedly attracted to wherever Seina happens to be, allowing the Galaxy Police to catch them in huge numbers. With Amane, Kiriko, Ryoko Balta, and others around him, the unlucky boy from Earth stumbles into training, battles, political attention, and romance while somehow becoming one of the force's most effective anti-pirate assets.
