I'm Giving the Disgraced Noble Lady I Rescued a Crash Course in Naughtiness manga volume 4 features story by Fukada Sametaro with art by Ichiho Katsura.

Life in the feared sorcerer Allen's mansion continues to grow more exciting with Charlotte's discovery of her hidden talent as a magical beast tamer and the addition of their newest family member, the fenrir pup Lü. The trio had just started to acclimate to their new routine when an unexpected plumbing issue unearths a secret fourth occupant of the estate with the power to kick them out of house and home. To satisfy her and secure their sanctuary, Allen and Charlotte must now pretend to be a couple deeply in love. The magic of art should never be taken lightly, however, and this foray into acting might just push them past the point of no return.
