Hikigaya doesn't want to be a force of strength

Hikigaya came to the strength supremacy classroom. Because of his sister's request, he must make ten friends before graduation.
For this slightly difficult requirement, Hikigaya decisively chose to lie flat.
"Air friends are also friends. Well, Komachi should be able to understand me."
However, three years passed.
Suzune Horikita, Arisu Sakayanagi, Kiyotaka Ayanokouji, Kikyo Kushida, Megumi Karuizawa, Sho Ryuen, Koenji...
Looking at a group of people of the same and opposite sex staring at him eagerly, Hikigaya fell into deep self-doubt.
Komachi, are these people really my brother's friends?
