Loner Life in Another World

An entire class of high school students is summoned to another world by its god, who selected them to become heroes. The god allowed each of the students to pick a special skill of their choice, but one of the students, Haruka, a loner student, tried to escape the selection ritual but got dragged along anyway, and the god allowed him to keep all the remaining skills the other students did not pick. Despite not having a single powerful skill, Haruka makes use of his multiple abilities to live a comfortable life by himself in the other world, until his classmates start having trouble trying to deal with their new environment and conflicts between them, forcing him to take action, leave his loner existence and help them.
