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...

At the lake house in Masaki Village, the preparations for Rea's wedding are in full swing. "I wanted to be married wearing the outfit that Kiyone-sama wore." With the thoughts for the late Kiyone being poured into her wedding dress, Akie, Kei, and the others continue the preparations. Meanwhile in space, Tennyo and Mikami watch over Airi working down the mountain of documents like a demon, all the while whining about missing Tenchi. Amidst all that, Minaho had reserved Tenchi for herself and spent all day with him, culminating in taking a bath together... "I'll give him back to you tomorrow, so please let me hog him for the rest of the day." Tenchi is moved by Minaho's semblance to his mother. The night quietly progresses...

On a particular day full of tension at the Masaki house, everybody is waiting for that moment. They are waiting for their new family member who will be Nobuyuki and Rea's first child and Tenchi's brother. With the entire Masaki family standing by, Tenchi's brother "Masaki Kenshi" lets out his first cry. But for Kenshi, this already marked the beginning of a heavy fate awaiting him. A few years later -- The women lead by Seto and Washu, and the men aiming to stop the women, lead by Juraian emperor Azusa and including the "Seto inhibitor" Seina, gather to discuss Kenshi's development. While the disquieting discussions continue, Kenshi's mother Rea makes a decision.
