Konjiki no Yami

Meet Golden Darkness, a mysterious 153 cm tall assassin with a vibe that screams nonchalance. Hired to take out Rito, a dude she later finds isn't so bad, she ends up hanging around Earth instead—seriously, does she even want to finish the job? Known as "Yami-chan," she spends her days lost in books and munching on her favorite snack, taiyaki, which has a special connection to Rito. With crazy skills that let her morph her limbs into anything from swords to dragon heads, she's got the raw power of a superhero but struggles with emotions and the whole "love" thing—awkward!
