Diseum, king of the Earlshide Kingdom, recommends Shin to attend his Magic Academy, on the agreement of not using Shin for political warfare. In the capital, Shin rescues two girls, Maria and Sicily, from thugs, and later he would inaugurate a club that consist him and others. A nonstandard boy's fantasy life starts here!

He is leadership of his own Ultimate Magic Research Society and is top S-rank. Sicily enamored with Shin from first meeting and is overjoyed when she becomes his fiancée. Like his grandfather he can cast magic without verbal or somatic components (since he considers aloud spell names embarrassing) and has created many unique spells like the gate and extra dimensional storage spaces. Based on recollection of his previous world, Shin's knowledge of science and astronomy revolutionize the world's magic tools.
