   Hi Mommy! Let me introduce you to the first book. It features an original female character who is Muzan's daughter, and it's really good! The second book has no original characters; all characters are from the original work. It's a Tanjiro and Muzan pairing, leaning towards Tanjiro-centric.

   I recommend these books. The first one is quite good, a family-themed story; you'll laugh when you see Muzan's exasperation with his children. The second one features a protagonist who was Muzan's fiancée in his human days, but later became his subordinate after turning into a demon; he's a demon cat immune to sunlight. The third one...

   The first book is about transmigrating into Muzan, with Kokushibo as the main character; it's relatively fast-paced. The second book is about transmigrating into Muzan, without a system, and the characters' personalities blend well; it's not out of character. The third book is about becoming Muzan's older brother (warning: Muzan might be out of character). The fourth and fifth books are about transmigrating into Kokushibo, with Muzan as the main character; both are sweet stories. The sixth book is about transmigrating into Muzan, with a single male lead; it's more casual.
