The tale begins around the end of the 3rd season...

Even with Nobuyuki and Rea's wedding coming up in a few days, the Masaki household, though busy with
preparations for the wedding, their everyday situation is still par for the course for the Masaki house.
In space too, people connected to the Masaki house are making preparations in order to attend the wedding.
Airi is battling mountains of paperwork, and Funaho, who can't attend the wedding because the survival of
Yosho hasn't been made public, gives her wedding gift to Minaho.
A few days before the wedding, people connected to the Masaki house gather on earth and Tenchi meets his aunt Minaho.
"...she reminds me of mom..." that's Tenchi's first impression, quite natural as she's also Airi's daughter.
The scent of trouble is in the air..
True, but those two are 
kind of exhausting, though.
صحيح، لكن ذلكما الاثنين مُتعِبان بعض الشّيء
Stimmt schon, aber die beiden
kosten immer Nerven.
Es que son
demasiado entusiastas para mí.
Es que son
demasiado entusiastas para mí.
Disons que je ne veux pas
gérer leurs conflits…
Vero, ma quelle due sono un po' estenuanti, 
per così dire.
É verdade, mas as duas
me cansam bastante.
Могу, только проводить время
с теми двумя довольно утомительно.
