    The first book is a coming-of-age story. The female lead is very powerful; she's turned into a demon by Mikoto, creates her own Snow Breathing technique, and knows the breathing techniques of Sun, Moon, Water, Wind, Fire, Lightning, and Rock. Her love interest is Shinobu Kocho (later in the story). The second book features a female lead who is both Mikoto and Yoriichi's older sister. She later becomes a demon, belonging to the third faction, the "Funniest" faction. The third book features a female lead who is the reincarnation of Shi, her love interest is Yoriichi, and she uses Sun Breathing. She becomes a demon for a period in the Sengoku period—specifically, the Taisho era. [Learned][Learned][Learned][Admiration][Admiration][Admiration]
