Later on in the story, Yuki meets Mikuru Asahina, a cute moe blob and Tsurya-san who is Mikuru's best friend, along with Haruhi Suzumiya who is an eccentric girl with an interest in aliens, time travelers, and espers, and Itsuki Koizumi, a "mysterious" transfer student who attends the same school as Haruhi.
