After a humiliating defeat, Hādo spent two years training withing the caverns, returning to the village occasionally for supplies and, on very rare occasions, important missions. During this time, he mapped out many of the tunnels, believing he had only scratched the surface when he finally ended his training. On several occasions, Hādo encountered several booby traps left over from the days of the Iwa. The most impressive being a summoning that spawned a 3 layered golem that required the assistance of both Yoru Kasai and Hinata Hyuga to defeat.
