They Said My Translator Skill Was Useless, but I Used It to Form an Invincible Party: How I Used My Power to Communicate with Monsters and Demons to Rise to the Top! @comic

The adventurer Zion, who possesses the "Translator" skill, the ability to understand the language of demons and animals, spends his days and nights on quests with his childhood friends in order to make the A-Class party. However, he is suddenly kicked out of the party because his abilities are not useful in battle. Disappointed, Zion makes a new start as a solo adventurer, thanks to the encouragement of Angelina, the guild receptionist. Later, several races join Zion's party, including a female slime swordsman and half-demon whose skills were deemed useless, and form a party of outsiders who are later described as heroes.
