This Devil Is a Master of Strategy

Some rats have been rampant recently. During the years when I was not the Demon King, I actually dared to invade my territory, massacre my people, plunder my wealth, and completely annihilate the existence of my Demon Clan with the slogan of justice. I remember, humans, beasts, elves and angels... They think that they can rest easy after driving their enemies to a dead end, and they can ridicule them, saying that the once arrogant demon clan has now come to an end, and the era of Thorfa has passed... Hum! Then let these arrogant guys once again remember the fear of being dominated by Demon King Thorfa. Declare the world and tell all the creatures in the Magic Continent that the king of the demons has returned with a settlement sheet! Narino passionately declares his goal to the Batmaid. Just now, he was transported into this magical medieval fantasy game world by three large vehicles, and he actually became the character "Tolfa" he created. Ambitious, he plans to make great achievements again. He is very excited because he is absolutely sure to revitalize the demon clan in the future. He knows all the magic in the world, knows the formula of any potion, is familiar with the characteristics of every creature, and has hundreds of ways to defeat the enemy... He is a strategy master who has cleared this game more than 2,000 times! "Lord Thorfa, you are so wise and powerful! Can you let the humble maid hang a cloak for you? You have been robbed by the enemy and only have a pair of underwear..." "What do you mean only one pair of underwear left? This is a swimsuit only. Look, I will throw away the underwear later. All I want is to start naked!" "Ah, so annoying~"
