In the other world, wield Earth’s knowledge as your weapon! On Earth, use magic from another world! A grand rise-to-power fantasy where a soul is shared across two worlds!! Dennis, the second son of an impoverished noble family, one day realizes that he shares his consciousness with Masaya, a middle-aged man from another world (Earth). Though initially bewildered by this bizarre situation, Dennis quickly recognizes that Masaya’s modern knowledge could be the key to restoring his territory’s failing economy. Determined to save his family and the people of his domain from ruin, Dennis begins taking action using Earth’s knowledge and innovations, while Masaya gains access to magic in his own world…!

I am not “useless”! I'll prove it by conquering dungeons! One day, magical dungeons suddenly appear in modern Japan, and life is completely transformed. Midorimu Sakaki was born with a talent for life magic, which doesn't help with dungeon exploration or defeating monsters. So even though his power level is the highest rank S, he was nevertheless scorned as useless and could only find work as a clerk at a magic academy. But by chance, he comes into possession of a rare item, “Sage System,” which allows him to create new types of magic during dungeon exploration. Now he can use the system to create life magic suitable for dungeon exploration, and finally take his first step to fulfill his dream as a dungeon adventurer! (Source: Kadokawa, translated)
