Yuuna and the Haunted Hot Springs Vol. 21

After a lifetime of dealing with succubus powers, Yumesaki-sensei might have suddenly found her cure! When a gorgeous student teacher, Narushi Ruka, appears at her school, she finds out that he's her male opposite number, an incubus! His powers are stronger, and he makes her an offer she can't refuse: he'll use his hypnosis powers to seal her succubus powers away. But when she finds out his hypnosis sealed away all her affection for Kogarashi in an effort to monopolize her love, she just can't let that slide. A sexy battle ensues! Who will come out on top, the succubus or the incubus?
