Tobun is a sword-master who is a hero in parts of the villages. He is known to have fought alongside the Cardboard Tube Samurai.
After his victory at Golden Pillar, Tobun returned home to find a sword, masterfully created, which he took. Unfortunately, the sword was cursed and forced him to burn towns and kill villagers. In the only moment that the sword lulled, he stabbed a dagger into his eye, but the sword would not let him die.
He impaled a man to a tree with a note to the Cardboard Tube Samurai, telling him to meet in Winter. They had a fearsome duel, but one which was futile as Tobun was defeated in combat. His last words, "before this moment, did I ever see the world?" represent his oblivious nature.
He was left in the snowy fields as a mark of respect and honour for dying on the battle field.
