Books by Osamu Takahashi

Souta Takatsuki and his neighbor Rikka Amanome have been like brother and sister since they were kids, but his feelings for her run much deeper. With her birthday coming up, he wants to find the perfect gift, which presents itself in the form of a book from a mysterious shop he happens across. The owner doesn't even charge him, saying he'll return to pay eventually...Souta is wholly unprepared for the insatiable passion the book inspires in Rikka, and it seems the ultimate price of this gift may be hefty indeed...

As summer break begins, Souta is drained more and more as he scrambles to satisfy the rampant sexual needs of Rikka, her friend Makoto, and now their teacher Shino. When Makoto learns of this third cursed lover, she hatches a plan to seek even greater depraved thrills. With Zepar’s help, she arranges an overnight camping trip to the beach. Trapped alone with Makoto and Shino, Souta will have no choice but to let his desires run wild…

"An occult tome turns Souta Takatsuki's life upside down when it transforms unrequited love into insatiable passion"--
