It's sushiiii!How first-class!Fatty tuna, sea urchin, and salmon roe are great!You may have the urchin, Mahiro.Ah, not a fan?Then you can have the fatty tuna instead.Urchin is probably a flavor for grown-ups. You'll change your mind when you eat a good one!Urrrchiiiiin...The first person to have eaten it must have been insane.Can't argue with that...
