Tenchi Forever!

Tenchi has been gone for six months after he disappeared into a portal in the woods. His friends are still searching for him, with Aeka and Ryoukou on Earth and Washuu, Sasami, Kiyone, and Mihoshi scouting the galaxy. When they finally locate Tenchi, they're surprised to find he's now living with another woman and seems to have forgotten them. His friends' reunion with Tenchi becomes complicated as they struggle to understand his new circumstances.
