The Haneda Airport is a Japanese airport which was attacked by Friend's minions in 1997 A.D. after the explosion was written in The Prophecy Book. At first Kenji though that it's going to be the Narita Airport that was going to be pulverized, but in his and Yukiji Setoguchi's encounter with Insu Manchome, Insu revealed that It's the Haneda Airport that is going to explode. Friend also took the time where Kenji was away from his convenience store to send his followers led by "The Leader" to invade the King Mart to capture the baby Kanna. From 2014 A.D. and so on, Yoshitsune settled down a new operation base to plan the resistance against Friend's humanity annihilation. The base seems to have an underground passageway connected to Friend Land.
