The 100 Year Repeat Student Elf

At Akitsu High School, a school with over a hundred years of history, there's one girl who never comes to school… As it turns out, she's an elf who transferred from another world and has been repeating the same grade for 100 years! When her classmate Ayumu visits the elf Elel in her room, what awaits him is a far cry from the mystical, beautiful elf he imagined... a sight so pathetically pitiful that it's almost unbelievable!
