Fukuyama Toshin was also sprinting down a dead end, desperately seizing wealth in hopes of giving his life a chance to restart.
After Prince Akihito's death, his body turned into a tree man. Fukuyama Toshin extracted a new medicine from the body that could resist the tree man's pollination, thereby extending his own 'life'.

After a round of negotiations, Fukuyama Toshin simply suggested they rob graves.
