Isekai Meikyuu de Harem wo

Struggling with life and society, high school student Michio Kaga wanders about the Internet and lands on an odd website. The website, featuring a number of questions and a point-based system, allows one to create skills and abilities for a character. Upon completing his character, Kaga was transported to a game-like fantasy world and reborn as a strong man who can claim idol-level girls. Thus begins the cheat and harem legend of a reborn man!
