My Journey to Another World with Godzilla

The earth-shattering battle between Godzilla and Destoroyah brought about the destruction of all Japan. In the end, Destoroyah, gravely wounded by Godzilla, tore open a rift in space at Mount Fuji and escaped. “It” naturally pursued it... As an unlucky armed guard at the Cheerful Fortress outpost, I had no choice but to take up the unfinished work of those who came before me and follow in Godzilla's footsteps, until time itself took him as well. Time? Heh... I wouldn't be surprised if he had even beaten time.
