After The Last

is a manga-omake set after the events of The Last: Naruto the Movie. In Japan it is included with Retsu no Sho. Its English translation is included with limited edition copies of The Last.

Summary
By checking Sai's books about proper human interaction, Naruto learns that men are supposed to pay for everything on a date. When he takes Hinata out to a restaurant, however, he is intimidated by how expensive the food is. Hinata uses her Byakugan to look inside his wallet and sees he doesn't have very much money on him. Not letting on that she knows this, Hinata asks if they can eat at Ramen Ichiraku instead, which a relieved Naruto agrees to.

Trivia

 * While it received no anime adaptation, the date is referenced by Naruto in Boruto: Naruto Next Generations episode 18.
