Why Do I Possess the God-Killing Gear When I Transform into Iruma?

When I traveled through time as Suzuki Iruma, I always thought it was an ordinary world, but when I was taken to the demon world by Grandpa Sullivan, I realized that I had traveled to Iruma-san and became a demon in this work. Although I had read the comics and felt that I could live a better life, why did God-killing tools such as the Dragon Hand of the Sekiryuutei and the Light Wings of the White Dragon Emperor appear in Sullivan's collection? Things are getting weirder and weirder. So what kind of story will Iruma bring to you as the Sekiryuutei and the White Dragon Emperor? I look forward to it next time This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
