## Plot

A young salaryman who died in an accident was reborn in another world filled with magic and demons. As a baby, he was picked up by the patriot hero "Sage" Merlin Wolford and was given the name Shin. He was raised as a grandson and soaked up Merlin's teachings, earning him some irresistible powers. However, when Shin became 15, Merlin realized, "I forgot to teach him common sense!" Diseum, king of the Earlshide Kingdom, recommends Shin to attend his Magic Academy, on the condition of not using Shin for political warfare. In the capital, Shin rescues two girls, Maria and Sizilien, from thugs, and later he inaugurates a club that consists of him and others.

## Characters
### Ultimate Magic Research Society
#### Shin Wolford (シン＝ウォルフォード, Shin Worufōdo)

    Voiced by: Yūsuke Kobayashi (Japanese); Daman Mills, Alison Viktorin (child) (English)
    A Japanese salaryman who worked for a science textbook publisher was killed by a truck and reborn into another world with his memories intact. Upon arriving in the new world, which was full of magic, he was raised and trained by Merlin Wolford, Melida Bowen, and Michel Collins, thereby making his magical and combat skills beyond S-rank. Shin can also create and modify magical gear to what can be considered National Treasure–level equipment. Being raised in the woods, however, his social and worldly skills are a bit lacking, though only by the standards of his new world. He has the leadership of his own Ultimate Magic Research Society and effortlessly tops S-rank. Sicily was enamored with Shin from their first meeting and is overjoyed when she becomes his fiancée. Like his grandfather, Shin can cast magic without verbal or somatic components (since he considers spoken spell names embarrassing) and has created many unique spells like the gate and extra-dimensional storage spaces. His element compresses in water and heat and his strongest attack is Hydrogen Bomb. Based on the recollection of his previous world, Shin's knowledge of science and astronomy revolutionize the world's magic tools. Over the summer break, Shin and his grandparents perform intensive training with the Ultimate Magic Research Society to prepare for massive demon outbreaks while deployed in a special unit called the Ultimate Magicians, hopefully, to prevent other academy students from getting conscripted into war. Soon afterward, Shin's (Earth-modern) appliances prompted him to open his own shopping mall. His title is Demon Lord, which he does not like.

Shin and Aug have a cousin-like relationship. Aug enjoys watching when Shin gets in over his head during social actions and likes to tease Shin to act on his plan. He also keeps Shin prudent from introducing new magic and tools that would throw the world out of balance. Aug's childhood friends, Julius and Thor, feel pressured because he talks to Shin casually.

With the Empire destroyed Schtrom claims he has achieved his goal and no longer needs an army, so he sets the Demonoids free. Miria questions his hatred of the Empire so Schtrom explains that he was a Lord of the Empire, but he disagreed with the Empire keeping slaves and made life for commoners as prosperous as possible. The other Lords hated him as most of their workforce moved to live on Schtrom’s lands, reducing their tax profits, so King Herald framed Schtrom for kidnapping commoners living on his land to sell as slaves. The furious commoners set fire to Schtrom’s home, killing his wife Aria and their unborn son. Fuelled by grief Schtrom demonised himself and swore to destroy the Blusfia Empire. Now having achieved his goal Schtrom becomes aimless.
