In the continent of Aleister, where dragon roars and magic are intertwined, trainee wizard Leo formed a strange adventure team by mistake. No one expected that their first mission would be to save the world: a chaotic force was quietly eroding the land. Along the way, everyone stumbled, laughed a lot, experienced misunderstandings, friendships and separations, and gradually uncovered the mystery of chaos. And hidden behind the casual humor are traces of each member's growth and self-transcendence. In the end, caught between humor and crisis, this "unreliable" adventure team became the continent's last hope. The whole book is humorous but compact and powerful. The ups and downs of the three volumes echo each other from beginning to end, bringing readers a relaxing yet profound fantasy adventure.
