After his introduction, Tomonori sat down to look at Ryūjirō dead in the eye.
"Woman, leave the room." Ryūjirō commanded his wife, "This fat bastard and I are gonna have a... civil conversation." Satoko followed her husband's orders and left her husband and unarguable son-in-law alone.

"I wanna start by congratulating you, Mr. Yokozawa." said Tomonori, "Harumi is the most wonderful woman I've ever had the pleasure to meet. She's kind, beautiful, clever, she loves me, I love her, and I'll put my life on the line for-"
But then Ryūjirō interrupted: "Cut the praise, fatass! No woman can be fascinated by sumo wrestling! I won't let you rot my daughter's brain any longer..." he said vehemently.
Tomonori was shocked by his father-in-law's embarassingly outdated views on what his daughter can or can't like. "It's not my fault that your daughter loves sumo so much!" yelled Tomonori before taunting the old cat, "She didn't move away from you just because she's an adult..."
Ryūjirō took grave offense to Tomonori's words, "Watch your mouth, fatty. You wouldn't sumo squish your father-in-law, would you?" In response to the boomer's threat, Tomonori rolled off his sleeve and placed his bare arm on the table. "I was thinking more... udezumō."

Ryūjirō accepted the challenge without a second thought. "I'm warning you, no one's ever beat me in this!"
The rules were simple: if Tomonori won, Ryūjirō would let his daughter be a rikijo, and if Ryūjirō won, Tomonori would never go near her again.
