Start with a Kurumi-Chan!

Because of an accident, I traveled to another world! He originally thought he was going to reach the top, but what he didn't expect was that the system could not be started due to an accident! He originally thought that life would be like this, but what happened next made him even more unexpected... He actually has a younger sister named Tokisaki Kurumi.... Then he discovered that his classmates actually had many familiar people! Tokisaki Kurumi: "Brother, get up and eat quickly!" Kasumigaoka Shiyu: "Hey! You scumbag!" The five Nakano sisters: "Hey, how do you do these questions? Tokisaki-san?" Mai Sakurajima: "Tokisaki-kun, maybe I like you more than you think!" Shinomiya Kaguya: "Yeah! Tokisaki-kun is so cute!" ... PS: This book is a time-travel novel by a daily writer, and the main world is "Honkai + multiple daily worlds"... This novel and its characters are purely fictitious.
