So, I decided to form a party with the three beauties in my class who were similarly thought to be useless (a Tsundere, a lolita and a meek girl)! But, it’s okay. I still have my Item Box and Item Shop. I’ll just have to make whatever it is I need! And so, I led a relaxed life in another world creating items DIY and hawking, but…… The Dragon Demon Lord and my past wife, a succubus comes knocking on my doorstep and seeking love. It seems that the transmigration this time is going to be troublesome yet again!
