Michibiki no Boukensha - Saitan Route de Saikyou Iki

Everyone looked down on Root, a so-called weak adventurer, because his only skill, Guide, could do nothing more than point out the safest path during a journey. One day, however, a party leader named Marx requested his help to guide them through the deadliest dungeon—one from which no one had ever returned. Root successfully led them to the deepest floor, but when he warned them about a deadly trap, they betrayed him, using him as bait to escape. Trapped inside the dungeon, with a ferocious dragon closing in, the true nature of Root’s skill awakened. Guide wasn’t just about showing paths—it revealed the solution to any problem he faced! Thus begins Root’s rise from the “weakest adventurer” to a hero who can overwhelm any foe and carve the shortest route to saving the world.
