The Seiryu Inves appeared when Kaito Kumon and Mai Takatsukasa found a portal back home. Kaito as Baron tried to fight it off, but its armor was too thick to break through with his Banaspear. Even help from Armored Riders Gaim and Ryugen didn't leave a scratch on it. Back in their world, Gaim changed to Pine Arms with the Pine Iron able to break through the armor. Baron then used his neglected Mango Lockseed to change into his Mango Arms where his Mango Punisher was able to break the Inves' armor. Even as the Seiryu Inves tried to fight back, it was destroyed by a combo attack between Gaim and Baron.
