Lanana-san wa Yakkai Elf!

Amane is a high school student who loves reading fantasy light novels. One day, a beautiful elf girl named Ranana transfers into his class—straight from another world.

Supposedly a member of a legendary Hero’s Party, she should be a cool and talented mage... or so he thought. In reality, she’s a "useless" elf in deep trouble, exiled from her world with a cursed choker!
