This body is forged by the sword, my blood flows like iron, my heart like glass... When Emiya the Great Warrior fights his way through the Holy Grail War in one night to save his sister, Miyu, he expects death. But when he opens his eyes again, he finds himself transported to the world of Musashi Reincarnation, and a new story begins. "Whether you are a dragon god or a human god, I will defeat you all to protect my family!" "Unlimited Blade Works!"

Hikigaya came to the strength-first classroom. Because of his sister's request, he had to make ten friends before graduation.

For this slightly more difficult requirement, Hikigaya decisively chose the lying-flat approach.

"Air friends are also friends. Well, Komachi should be able to understand me."

However, three years have passed.

Horikita Suzune, Sakayanagi Arisu, Ayanokouji Kiyotaka, Kushida Kikyo, Karuizawa Megumi, Ryuen Sho, Koenji...

Looking at a group of people of the same sex and opposite sex who were staring at him covetously, Hikigaya fell into deep self-doubt.

Komachi, are these people really my brother's friends?
