## Description
This is doujin circle initial’s debut work. The ultra-siscon Haruto was brought to a new world with his two imoutos Yuno and Chika. A sukumizu-clad girl who called herself ‘Kami-sama’ had brought them to Sistopia and bestowed an icharabu gauge on Haruto to grant his wish. He found it awfully bizarre, but after living in Sistopia for a bit, he found that it was a relatively normal place, except that the only ones in this world were him and his imoutos. There’s a sole purpose to this world: icharabu with imoutos!
