100-nen Ryuunen Shiteru Elf

Akitsu High School boasts over a century of tradition, but its halls hold a secret far stranger than any dusty archive. Among its student body is Elel, a girl who has never once attended a single day of class—and for good reason. She is not a truant, but an elf from another world who has been stuck repeating the same grade for a hundred years. While her classmates have long since graduated and moved on, Elel remains eternally enrolled, confined to her room within the school, trapped in an endless loop of academic stagnation. When the curious and well-meaning Ayumu decides to pay this mysterious transfer student a visit, he braces himself for the ethereal, otherworldly beauty of a legendary elf. What he finds instead shatters every fantasy: a scrawny, pathetic little creature so utterly helpless and disheveled that she defies all imagination. Far from majestic, Elel is the very picture of weakness, surviving on sheer luck and the bare minimum of elf dignity. Thus begins a high-energy romantic comedy where Ayumu's ordinary life collides with the most adorably useless elf in existence. Through their chaotic daily interactions, laughter erupts at every turn, yet beneath the slapstick and absurdity grows a surprisingly warm bond—a heart-tugging tale of two misfits finding connection in the most unlikely of classrooms.
