He is sent on a mission with his team and is later the only person to return to Konoha. On his return, he is spotted by the Konoha gate guards and collapsed. He is later questioned by Minato in the Konoha Hospital. All he's able to remember about his encounter with the enemy is "Ageha" butterflies.

Trivia
