Sensei: "You do not have ninja intuition, you do not even have normal intuition."
While sneaking into Tanley's mansion, Haru gets chased by Tanley's dog, hits himself in the head with an antenna, and causes Gobei to fall off the building.
Concierge: Perhaps I shall send Dom Pérignon (champagne) to your room.
Haru: I prefer to be alone tonight, perhaps later I will meet your friend Don.
During the fight in the sushi bar, a Kobudosai gang member rips off Gobei's "hair" which ends up pressing his Berserk Button as he just ruined his disguise. "You know how long it took me to grow my hair?!"
Haru: Yes, the mainland! The sea is foaming! You have wandered way off course!
When Haru sneaks into Tanley's warehouse, he forces himself to climb up a palm tree. He then swings from the palm tree to catapult himself into the warehouse to the tune of Tarzan Boy.
At the end, when Haru drives off with Alison, he ends up grabbing Gobei's wheelchair, and he eventually hits a rock, plummeting him into the ocean below. The movie ends with Haru yelling, "I am sorry, big brother!"
