Itsuki Ichigohara is a married high-school teacher in her late 20's, who finds herself involved with a high school girl, her student, who is 10 years younger. The student's name is Rin Togawa. She is taller than Itsuki, with a beautiful face, mild-mannered but a little childish. She is a good girl, but she has had problems in her family life, and as Itsuki tried to counsel her, they somehow ended up kissing each other in bed. This is definitely an adulterous betrayal, not to mention a crime. How could she have got herself into so much trouble that could only lead to her own destruction? — How could I have let this happen? It is a lewd and immoral, but somehow warm relationship. A love story between a female teacher and her female student. (Source: Kadokawa, translated)

Prequel to the anime about Sakuya's introduction to The World.

There is a world where there is no end to those who seek spirits and those who hunt spirits. In this world, there was a baby who was abandoned by his real parents as a detester to black hair and black eyes. The name of this child is Wilm. Picked up by the spirits, he grew into a summoner who protects his beloved sisters and the beloved village. "I won't tolerate the guy who dares to touch my family!" The blunt and summoned beast sisters shake the world. An exhilarating summoning battle fantasy begins now!

It‘s a mysterious and haunting series about a man (?) who is tossed about in time and space, never knowing who he is or why he's fated to be a perpetual voyager. His name is Facade, and he shares his body with four other entities- Wolf Face, a male wolf who has mastered human speech; Twin, a female swan with a double pair of wings; the Professor, who is pure personality without a body of his own; Naaku, a dragon (sex evidently unknown- maybe dragons don't have them); and a fifth person who has yet to appear and about whom nothing is known. Sometimes Facade's co-tenants manifest in their own bodies, sometimes they merely change part of Facade's body into their own. This allows Facade, for instance, to fly with Twin's wings or, in one unusually happy tale in the first volume, to manifest as the god Anubis to a number of ancient Egyptians by grafting Wolf Face's head onto his own human body.
