おっさんは用済みだ、とSランクパーティを追放された剣士ケネス。 しかし彼の正体は、知る人ぞ知る「最強の暇人」。そもそもパーティ活動すら、彼にとっては暇つぶしに過ぎなかったのだ! そして、ケネスは新たな暇つぶしを求め、前人未踏とされる「神々の迷宮」へ挑むことに。 攻略の途中で出会った銃使いのリリーと魔法使いのカレンを仲間にしたケネスは、規格外の剣術で迷宮の主である神相手にも無双してしまい――!? 凄腕だけど暇人のおっさんと美少女達の、最強で最高な英雄譚が今、爆誕!! “You’re over the hill, old man.” With those words, the swordsman Kenneth is unceremoniously kicked out of his S-rank adventurer party. What they don’t know is that Kenneth’s true identity is the legendary “Ultimate Idle Master,” known only to a select few. To him, party adventuring was never more than a way to kill time. In search of a new cure for his boredom, Kenneth sets his sights on the uncharted Labyrinth of the Gods, a dungeon said to be impossible for mortals to conquer. Along the way, he teams up with Lily, a gunslinger, and Karen, a skilled mage. With his off-the-charts swordsmanship, Kenneth proceeds to overwhelm the labyrinth, dominating even the gods who rule it…!! Thus begins the ultimate heroic tale of an absurdly powerful yet perpetually bored middle-aged swordsman and the beautiful girls who join him!
