Toaru Ossan no VRMMO Katsudouki (Manga)

A Playthrough of a Certain Dude's VRMMO Life (とあるおっさんのVRMMO活動記, Toaru Ossan no VRMMO Katsudōki) is a Japanese Manga written by Shiina Howahowa and illustrated by Shūya Rikudō.

Synopsis
Tanaka Taichi is an ordinary Japanese guy who's just made a new character, "Earth," in a brand new open-world VRMMO game called "One More Free Life Online" that promises almost unlimited freedom. In a world where players are free to challenge monsters with all their strength or go on adventures at their own pace, Taichi chooses to master the most worthless skills the game has to offer! Sometimes he'll make overly complicated potions, or food that tastes much better than it has any reason to. And sometimes he'll go hunt monsters with crazy, hand-made weapons... An ordinary dude is about to begin his own VRMMO fantasy life!
