Suwa Midoriko is an academic with a secret ability to cleanse cursed objects by touching them. So why doesn’t it seem to work on this ritual dagger donated to the museum where she works?

It had to be removed from the exhibit, but theft wasn’t what she had in mind! Enter an infamous phantom thief–a man of many names and faces. He wants the dagger, but Midoriko won’t let him have it without putting up a fight!

“Sorry, but I can’t let you go now…You’ve seen my real face.”

After discovering that there’s more to her abilities than she previously thought, Midoriko finds herself entangled in a criminal underworld full of dangerous sorcerers. Unable to escape this fate, she has no choice but to rely on the thieving wizard who dragged her into this situation to begin with.

He may have stolen the dagger, but can he steal Midoriko's heart, too?
