The Gate 9 crew is visiting the robot graveyard as part of their quest to save the world from a cosmic threat. It contains many pieces of high technology but a strange ecosystem has sprung around it. The heroes must navigate the various hazards, deal with the local inhabitants, and fight a powerful villain. All in a day’s work for the Gate 9 crew!

The year is Tenshō 10, in the Twelfth month. Six months ago the betrayer Akechi Mitsuhide attacked his master Oda Nobunaga at Honnō-ji, burning it to the ground along with the demon warlord. Snowfall covers the mainland, and a time that should be spent in contemplative seclusion is now spent in clandestine war meetings. Stillness and oppressive silence envelope the countryside, but whispers of secret treachery fill the halls of every daimyō. In Settsu province, Lord Inukai and his loyal retainers meet to discuss the coming war for the title of Shogun.

A being from beyond time and space now threatens a major city. Only the Gate 9 crew can stop the monster’s hunt but to do so, they must confront it directly, trapped in the city. Faced between saving civilians and fighting the monster, the team has to split up to save the day. Can they succeed?

A secret war has begun in the shadows. Two cults, one led by the spirit Logos and the other by Haruspex, a powerful psychic, vie for domination. The Gate 9 crew does not trust either group, so they must find what they are doing and put a stop to it. They will need allies for this mission, so they must find them…

The Biobuddy fighting circuit is a dark and dangerous subculture, where money is more important than anything else. Trainers do everything to get their Biobuddy to win arena fights, even if it means dirty tricks. In order to take over the Biobuddy circuit, the Gate 9 crew needs to identify the major players and that means going undercover.
