I Absolutely Don't Want to Work as the Dungeon Master Until I Indulge in My Laziness / Lazy Dungeon Master / ช่วยขยันหน่อยได้ไหมนายดันเจียนมาสเตอร์ / 絕對不想工作的地下城城主想睡懶覺 / 絶対に働きたくないダンジョンマスターが惰眠をむさぼるまで,

Masuda Keima, a lazy high school student who would rather relax than work, is summoned to a dungeon as a monster by Dungeon Core No. 695. She is the core of Ordinary Cave, a powerful dungeon consisting of just one room. The dungeon core accidentally names Keima her Dungeon Master. His first challenge is to deal with bandits camped near the heat-emitting core, before they decide to destroy it and kill them both.
