Jūgo Arc
When word reached Konohagakure about birds randomly attacking a village, Tosaka was requested to work alongside Team 7 and Team 15. Along the way, Tosaka would continuously analyse any evidence of birds in the area, at times grossing out some of his allies. Upon arriving, the group was attacked by strange-looking birds. At the village, they learned that many people attacked by the mutated birds quickly became sick and were covered in Cursed Seals. The villagers also found an unconscious Jūgo, who was recognised by Sarada and Mitsuki. When the man awoke and was questioned, one the sick villagers went on a feral rampage and attacked Tosaka until he was suddenly drawn to Jūgo.
