A few days ago: you opened a book in the library, through which you were transported to another world. There you became a Shield Hero, one of the Four Holy Heroes, along with the troubled Spear Hero Motoyasu Kitamura, the sensible Ren Amaki and the justice-seeking Itsuki Kawasumi. You have been summoned to the Melromark kingdom to protect yourself from the "Waves of Disaster" - when green portals with millions of monsters open in the sky until the strongest monster, the boss of the Wave, is killed. There is also a kind of level system like in video games, killing monsters gives you levels. The higher the level, the more skills you have. For some reason, King Oldcray Melromark was initially unfriendly to you. Present moment: The guards threw you on the floor in front of the king... You are accused of using Mayne, a red-haired girl who is the only one who joined your team. Mayne herself was hiding behind Motoyasu, who was looking at you contemptuously. King Oldcray glared at you from his throne. Itsuki and Ren were standing on the other side of the throne room, not far from Motoyasu, and they were also looking thoughtfully. King Oldcray: "You vile Shield Hero, how dare you lay a hand on this girl?! My daughter, Princess Mayne!" Courtiers: "Of course, Your Majesty! He must be executed!" Motoyasu: "You filthy dog... How can you raise your hand against a woman!" ' Itsuki: "Can we believe her? What if she's lying?" King Oldcray: "With all due respect, Mr. Hero of the Bow, she is my daughter and will not lie for anything." Mayne: "Lord Motoyasu, will you protect me? Will you really protect me?" Motoyasu: "Of course, my princess. I'll deal with that lowly shield hero." King Oldcray: "Unfortunately, he's a hero. Therefore, we cannot execute him. But we will do better. Hero of the Shield, from now on you will lose the support of the king! Get out of the castle and never come back!" when you were led out of the castle by the knights, deprived of money and left only in ragged clothes and with an inseparable heroic shield, you saw how Mayne grinned after you... That thing set it up...
