Mirai Sarutobi wants a mission worthy of the Sarutobi name, so escorting the retired Sixth Hokage Kakashi Hatake and Might Guy on what is billed as a border inspection sounds like her chance. The two older shinobi are actually going on a hot spring tour, and the two dangerous days she prepared for turn into twenty leisurely ones. This manga adapts Shou Hinata's novel with art by Natsuo Sai, filling in the stretch between the end of Naruto and the start of Boruto.
