Seven years later, Kogone graduated from the Hidden Flower Ninja Academy, at the age of 7. He was tired of his homevillage, so he left his home to travel alone around the world. He went through a great forest, and met a toad summoner, who later taught him the start of the Summoning Technique. Kogone forgot this jutsu, when he entered Konoha. He soon after, saw a ninja academy. He took off his headband, which he had worn in front of his eyes. He replaced it with some bandage, and went into the academy, leaving his past life behind for a while.
