I, the Brave Man, Why Summon the Devil?

Lance traveled to a fantasy world. Here, as long as you kill the hero with your own hands, you can take away the hero's power. Wild heroes will gradually lose their minds and be slandered as demons by the royal family. If caught, they will be executed. And the royal family's domestic version of the brave is not much better. They want to beg for mercy from the royal family and get the treasure to restore their sanity from the royal family. You must also always be on guard against sneak attacks from those who desire to seize the hero's power. Lance looked at the word [brave] on his panel and remained silent. Until he scrolled down: [You will obtain a special ability, which will rotate every seven days. [Ability this week: Summoning of Heroic Spirits. You can summon a famous person from the history of this world to fight for you. 'Whee. ' Lance laughed. The summoning of heroic spirits went smoothly, and he even summoned the legendary world's strongest... The last demon king? 'No hee hee. ' Lance was silent again. ------------------ This book is also known as "This brave man's ability is refreshed every week", "Miss Demon King wants to rule the world", "This adventurer always takes out strange things" Elements: [Hodgepodge Fantasy World View], [Pseudo-DND], [Easy]
