Han was a shinobi from Iwagakure and was the host of the Five-Tailed Beast, as well as the physically largest jinchūriki, easily standing a head taller than Kirābī. The Five-Tails has been captured and sealed by Akatsuki, causing this jinchūriki's death when the beast was extracted. Another jinchūriki, named Rōshi, who held the Four-Tailed Beast, also originated from Iwagakure. It is logical to assume that he and Rōshi knew each other as they were both jinchūriki of the same village.
