Stranger's Handbook

The main character is suddenly summoned to another world.....and the one who shows up next is a malicious and scheming noble.....obey or die. I’ll try to rise in this world and live on by any means! It’s the story of such a hero. Comedy and serious scenes? I’m the type that won’t let his guard down even when my magical powers are at a cheat level, I take my medicine while scheming wickedly. Was I only scared of my surroundings in the beginning? Well, I’ll do my best to become an indispensable hero!
