Unqualified Heroes

When Yusuke Yotsuya wonders how the model student, Iu Shindo, and the ever-so-sick, Kusue Hakozaki, get along with each other, he gets transferred to another world. Between Shindo who can only manipulate wind, Hakozaki who is a warrior who can't wield her sword, and Yotsuya whose weapon is just a sickle and a hoe, they face a troll.
