Shigatsubaka-tachi no Utage

In the year 20XX, a crisis looms over the Earth.
From the planet Okonomi, 40 light years away from the earth, a super-extinct, annihilating monster took off. This unknown monster, which had repeated 365 times through hyperspace warp, finally attacked the earth. NASA, which had already learned of this fact early on, reported the situation to the United States and the United Nations. Mankind rallied all its resources and completed a humanoid weapon against the Kaijuu.
