My Childhood Friend Stole My Class

Hisomu and Yuki, his childhood friend, are ran over by a truck and are on their way to being reincarnated in another world. However, Yuki doesn't like her class. She convinces the goddess in charge of their reincarnation into swapping her class with Hisomu's, which wouldn't be that big of a deal except that Yuki's class is only meant for girls!
