"Fade into the Moonlight" (月光に消ゆ, Gekkō ni Kiyu) is episode 307 of the Naruto: Shippūden anime.
With a break in the fighting, the Allied Shinobi Forces tend to the dead and injured. The Logistical Support and Medical Division camp is ablaze with activity as medical-nin try their best to save their comrades. Elsewhere, Kabuto notes the body count climbing and decides to take further action. Summoning a confused Hayate Gekkō, Kabuto fills him in on what had happened leading up to and after his death. At the medical camp, the corpses of shinobi with kekkei genkai and clans deemed important are being documented and sealed away to be returned after the war. Wanting to take the opportunity to collect samples, Kabuto reincarnates a Suna and Kumogakure shinobi to form a team with Hayate. This team infiltrates the medical division's camp and causes mayhem on the ground. There, they steal the KIA scroll that was being formulated by the medics. As they make their escape, the medics form a team to pursue them in order to retrieve the list. With the request that Yūgao join the team, she protests that she could not, as Hayate was her former lover.
