Bleach

(As always, age up all characters involved in the sex to be at least 18.)

The Lamp entered a rather interesting universe, with the world split into three main separate ones, and a few minor ones, maintained by an immense power at a central point. It was quite a fascinating system... one the Lamp ultimately had no interest in. So long as the system didn't collapse in on itself while it was here, forcing it to move universes, it cared little for the intricacies, other than mechanics it needed to operate by to maintain minimal disruption.

As such, it simply picked one of the worlds to descend in, and descend it did, to await the fulfillment of its purpose.
